Here are some events that happened on June 7th. It could be an event or a person that died or was born on that day


1826 Died: Joseph von Fraunhofer, German optician, physicist, and astronomer (b. 1787)

Joseph Ritter von Fraunhofer (6 March 1787 – 7 June 1826) was a Bavarian physicist and optical lens manufacturer. He made optical glass and achromatic telescope objective lenses, invented the spectroscope, and developed diffraction grating. In 1814, he discovered and studied the dark absorption lines in the spectrum of the sun now known as Fraunhofer lines.

One of the most difficult operations of practical optics during the time period of Fraunhofer's life was accurately polishing the spherical surfaces of large object glasses. Fraunhofer invented the machine which rendered the surface more accurately than conventional grinding. He also invented other grinding and polishing machines and introduced many improvements into the manufacture of the different kinds of glass used for optical instruments, which he always found to have flaws and irregularities of various sorts

By 1814, Fraunhofer had invented the modern spectroscope. In the course of his experiments, he discovered a bright fixed line which appears in the orange color of the spectrum when it is produced by the light of fire. This line enabled him afterward to determine the absolute power of refraction in different substances. Experiments to ascertain whether the solar spectrum contained the same bright line in orange as the line produced by the orange of fire light led him to the discovery of 574 dark fixed lines in the solar spectrum. Today, millions of such fixed absorption lines are now known.

Continuing to investigate, Fraunhofer detected dark lines also appearing in the spectra of several bright stars, but in slightly different arrangements. He ruled out the possibility that the lines were produced as the light passes through the Earth’s atmosphere. If that were the case they would not appear in different arrangements. He concluded that the lines originate in the nature of the stars and sun and carry information about the source of light, regardless of how far away that source is. He found that the spectra of Sirius and other first-magnitude stars differed from the sun and from each other, thus founding stellar spectroscopy. 

These dark fixed lines were later shown to be atomic absorption lines, as explained by Kirchhoff and Bunsen in 1859. These lines are still called Fraunhofer lines in his honor; his discovery had gone far beyond the half-dozen apparent divisions in the solar spectrum that had previously been noted by Wollaston in 1802.

The German research organization Fraunhofer Society is named after him and is Europe's biggest Society for the Advancement of Applied Research.

1862 Born: Philipp Lenard, Slovak-German physicist and academic, Nobel Prize laureate (d. 1947)

Philipp Eduard Anton von Lenard (7 June 1862– 20 May 1947) was a Hungarian-born German physicist and the winner of the Nobel Prize for Physics in 1905 for his work on cathode rays and the discovery of many of their properties. One of his most important contributions was the experimental realization of the photoelectric effect. He discovered that the energy (speed) of the electrons ejected from a cathode depends only on the wavelength, and not the intensity, of the incident light.

Lenard was a nationalist and anti-Semite; as an active proponent of the Nazi ideology, he supported Adolf Hitler in the 1920s and was an important role model for the "Deutsche Physik" movement during the Nazi period. Notably, he labeled Albert Einstein's contributions to science as "Jewish physics".

As a physicist, Lenard's major contributions were in the study of cathode rays, which he began in 1888. Prior to his work, cathode rays were produced in primitive, partially evacuated glass tubes that had metallic electrodes in them, across which a high voltage could be placed. Cathode rays were difficult to study using this arrangement, because they were inside sealed glass tubes, difficult to access, and because the rays were in the presence of air molecules. Lenard overcame these problems by devising a method of making small metallic windows in the glass that were thick enough to be able to withstand the pressure differences, but thin enough to allow passage of the rays. Having made a window for the rays, he could pass them out into the laboratory, or, alternatively, into another chamber that was completely evacuated. These windows have come to be known as Lenard windows. He was able to conveniently detect the rays and measure their intensity by means of paper sheets coated with phosphorescent materials.

Lenard observed that the absorption of cathode rays was, to first order, proportional to the density of the material they were made to pass through. This appeared to contradict the idea that they were some sort of electromagnetic radiation. He also showed that the rays could pass through some inches of air of a normal density, and appeared to be scattered by it, implying that they must be particles that were even smaller than the molecules in air. He confirmed some of J. J. Thomson's work, which eventually arrived at the understanding that cathode rays were streams of negatively charged energetic particles. He called them quanta of electricity or for short quanta, after Helmholtz, while Thomson proposed the name corpuscles, but eventually electrons became the everyday term. In conjunction with his and other earlier experiments on the absorption of the rays in metals, the general realization that electrons were constituent parts of the atom enabled Lenard to claim correctly that for the most part atoms consist of empty space. He proposed that every atom consists of empty space and electrically neutral corpuscules called "dynamids", each consisting of an electron and an equal positive charge.

As a result of his Crookes tube investigations, he showed that the rays produced by irradiating metals in a vacuum with ultraviolet light were similar in many respects to cathode rays. His most important observations were that the energy of the rays was independent of the light intensity, but was greater for shorter wavelengths of light.

These latter observations were explained by Albert Einstein as a quantum effect. This theory predicted that the plot of the cathode ray energy versus the frequency would be a straight line with a slope equal to Planck's constant, h. This was shown to be the case some years later. The photo-electric quantum theory was the work cited when Einstein was awarded the Nobel Prize in Physics in 1921. Suspicious of the general adulation of Einstein, Lenard became a prominent skeptic of relativity and of Einstein's theories generally; he did not, however, dispute Einstein's explanation of the photoelectric effect. Lenard grew extremely resentful of the credit accorded to Wilhelm Röntgen, who received the first Nobel Prize in physics in 1901, for the discovery of the X-ray, despite the fact that Röntgen was German and a non-Jew. Lenard wrote that he, not Roentgen, was the “mother of the X-rays,” since he had invented the apparatus used to produce them. Lenard likened Röntgen’s role to that of a “midwife” who merely assists with the birth.

Lenard received the 1905 Nobel Prize for Physics in recognition of this work.

1879 Born: Knud Rasmussen, Danish anthropologist and explorer (d. 1933)

Knud Johan Victor Rasmussen (7 June 1879 – 21 December 1933) was a Greenlandic–Danish polar explorer and anthropologist. He has been called the "father of Eskimology" and was the first European to cross the Northwest Passage via dog sled. He remains well known in Greenland, Denmark and among Canadian Inuit.

He went on his first expedition in 1902–1904, known as The Danish Literary Expedition, with Jørgen Brønlund, Harald Moltke and Ludvig Mylius-Erichsen, to examine Inuit culture. After returning home he went on a lecture circuit and wrote The People of the Polar North (1908), a combination travel journal and scholarly account of Inuit folklore. In 1908, he married Dagmar Andersen.

In 1910, Rasmussen and friend Peter Freuchen established the Thule Trading Station at Cape York (Qaanaaq), Greenland, as a trading base. The name Thule was chosen because it was the most northerly trading post in the world, literally the "Ultima Thule". Thule Trading Station became the home base for a series of seven expeditions, known as the Thule Expeditions, between 1912 and 1933.

The First Thule Expedition (1912, Rasmussen and Freuchen) aimed to test Robert Peary's claim that a channel divided Peary Land from Greenland. They proved this was not the case in a remarkable 1,000 kilometres (620 mi) journey across the inland ice that almost killed them. Clements Markham, president of the Royal Geographical Society, called the journey the "finest ever performed by dogs." Freuchen wrote personal accounts of this journey (and others) in Vagrant Viking (1953) and I Sailed with Rasmussen (1958).

The Second Thule Expedition (1916–1918) was larger with a team of seven men, which set out to map a little-known area of Greenland's north coast. This journey was documented in Rasmussen's account Greenland by the Polar Sea (1921). The trip was beset with two fatalities, the only in Rasmussen's career, namely Thorild Wulff and Hendrik Olsen. The Third Thule Expedition (1919) was depot-laying for Roald Amundsen's polar drift in Maud. The Fourth Thule Expedition (1919–1920) was in east Greenland where Rasmussen spent several months collecting ethnographic data near Angmagssalik.

Rasmussen's "greatest achievement" was the massive Fifth Thule Expedition (1921–1924) which was designed to "attack the great primary problem of the origin of the Eskimo race." A ten volume account (The Fifth Thule Expedition 1921–1924 (1946)) of ethnographic, archaeological and biological data was collected, and many artifacts are still on display in museums in Denmark. The team of seven first went to eastern Arctic Canada where they began collecting specimens, taking interviews (including the shaman Aua, who told him of Uvavnuk), and excavating sites.

Rasmussen left the team and traveled for 16 months with two Inuit hunters by dog sled across North America to Nome, Alaska – he tried to continue to Russia but his visa was refused. He was the first European to cross the Northwest Passage via dog sled. His journey is recounted in Across Arctic America (1927), considered today a classic of polar expedition literature. This trip has also been called the "Great Sled Journey" and was dramatized in the Canadian film The Journals of Knud Rasmussen (2006).

For the next seven years Rasmussen traveled between Greenland and Denmark giving lectures and writing. In 1931, he went on the Sixth Thule Expedition, designed to consolidate Denmark's claim on a portion of eastern Greenland that was contested by Norway.

The Seventh Thule Expedition (1933) was meant to continue the work of the sixth, but Rasmussen contracted pneumonia after an episode of food poisoning attributed to eating kiviaq, dying a few weeks later in Copenhagen at the age of 54.

1954 Died: Alan Turing, English mathematician and computer scientist (b. 1912)

Alan Mathison Turing (23 June 1912 – 7 June 1954) was an English mathematician, computer scientist, logician, cryptanalyst, philosopher, and theoretical biologist. Turing was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general-purpose computer. Turing is widely considered to be the father of theoretical computer science and artificial intelligence. Despite these accomplishments, he was not fully recognised in his home country during his lifetime, due to his homosexuality, and because much of his work was covered by the Official Secrets Act.

During the Second World War, Turing worked for the Government Code and Cypher School (GC&CS) at Bletchley Park, Britain's codebreaking centre that produced Ultra intelligence. For a time he led Hut 8, the section that was responsible for German naval cryptanalysis. Here, he devised a number of techniques for speeding the breaking of German ciphers, including improvements to the pre-war Polish bombe method, an electromechanical machine that could find settings for the Enigma machine.

Turing played a crucial role in cracking intercepted coded messages that enabled the Allies to defeat the Nazis in many crucial engagements, including the Battle of the Atlantic, and in so doing helped win the war. Due to the problems of counterfactual history, it is hard to estimate the precise effect Ultra intelligence had on the war, but at the upper end it has been estimated that this work shortened the war in Europe by more than two years and saved over 14 million lives.

After the war Turing worked at the National Physical Laboratory, where he designed the Automatic Computing Engine. The Automatic Computing Engine was one of the first designs for a stored-program computer. In 1948, Turing joined Max Newman's Computing Machine Laboratory, at the Victoria University of Manchester, where he helped develop the Manchester computers and became interested in mathematical biology. He wrote a paper on the chemical basis of morphogenesis and predicted oscillating chemical reactions such as the Belousov–Zhabotinsky reaction, first observed in the 1960s.

Turing was prosecuted in 1952 for homosexual acts; the Labouchere Amendment of 1885 had mandated that "gross indecency" was a criminal offence in the UK. He accepted chemical castration treatment, with DES, as an alternative to prison. Turing died in 1954, 16 days before his 42nd birthday, from cyanide poisoning. An inquest determined his death as a suicide, but it has been noted that the known evidence is also consistent with accidental poisoning.

In 2009, following an Internet campaign, British Prime Minister Gordon Brown made an official public apology on behalf of the British government for "the appalling way he was treated". Queen Elizabeth II granted Turing a posthumous pardon in 2013. The "Alan Turing law" is now an informal term for a 2017 law in the United Kingdom that retroactively pardoned men cautioned or convicted under historical legislation that outlawed homosexual acts.

Here are some events that happened on March 16th. It could be an event or a person that died or was born on that day

1581 Born: Pieter Corneliszoon Hooft, Dutch historian and poet (d. 1647)

Pieter Corneliszoon Hooft (16 March 1581 in Amsterdam – 21 May 1647 in The Hague) - Knight in the Order of Saint Michael - was a Dutch historian, poet and playwright who lived during the Dutch Golden Age.

Pieter Corneliszoon Hooft, often abbreviated to P.C. Hooft, was born in Amsterdam as the son of the then mayor, Cornelis Hooft. Hooft was also uncle to Cornelis and Andries de Graeff.

In 1598, in preparation for his career as a merchant, his father sent him to France and Italy, but Pieter Corneliszoon Hooft was more interested in art and was deeply impressed by the Italian renaissance.

Hooft was a prolific writer of plays, poems and letters, but from 1618 onwards he concentrated on writing a history of the Netherlands (Nederduytsche Historiën), inspired by Roman historian Tacitus. His focus was primarily on the Eighty Years' War between the Netherlands and Spain and though he tried to be as impartial as possible, he did succeed.

As a poet, he was influenced by his Renaissance contemporaries in France and Italy.

1751 Born: James Madison, American academic and politician, 4th President of the United States (d. 1836)

James Madison Jr. (March 16, 1751 – June 28, 1836) was an American statesman, lawyer, diplomat, philosopher and Founding Father who served as the fourth president of the United States from 1809 to 1817. He is hailed as the "Father of the Constitution" for his pivotal role in drafting and promoting the Constitution of the United States and the United States Bill of Rights. He co-wrote The Federalist Papers, co-founded the Democratic-Republican Party, and served as the fifth United States secretary of State from 1801 to 1809.

Born into a prominent Virginia planter family, Madison served as a member of the Virginia House of Delegates and the Continental Congress during and after the American Revolutionary War. He became dissatisfied with the weak national government established by the Articles of Confederation and helped organize the Constitutional Convention, which produced a new constitution to supplant the Articles of Confederation. Madison's Virginia Plan served as the basis for the Constitutional Convention's deliberations, and he was one of the most influential individuals at the convention. Madison became one of the leaders in the movement to ratify the Constitution, and he joined with Alexander Hamilton and John Jay in writing The Federalist Papers, a series of pro-ratification essays that was one of the most influential works of political science in American history.

After the ratification of the Constitution, Madison emerged as an important leader in the United States House of Representatives and served as a close adviser to President George Washington. He was the main force behind the ratification of the United States Bill of Rights, which enshrines guarantees of personal freedoms and rights within the Constitution. During the early 1790s, Madison came to oppose the economic program and accompanying centralization of power favored by Secretary of the Treasury Alexander Hamilton. Along with Thomas Jefferson, Madison organized the Democratic-Republican Party, which was, alongside Hamilton's Federalist Party, one of the nation's first major political parties. After Jefferson won the 1800 presidential election, Madison served as secretary of State from 1801 to 1809. In that position, he supervised the Louisiana Purchase, which doubled the size of the United States.

Madison succeeded Jefferson with a victory in the 1808 presidential election. After diplomatic protests and a trade embargo failed to end British attacks against American shipping, he led the United States into the War of 1812. The war was an administrative morass and ended inconclusively, but many Americans saw it as a successful "second war of independence" against Britain. The war convinced Madison of the necessity of a stronger federal government, and he presided over the creation of the Second Bank of the United States and the enactment of the protective Tariff of 1816. He retired from public office in 1817 and died in 1836. Madison is considered to be one of the most important Founding Fathers of the United States, and historians have generally ranked him as an above-average president.

1815 – Prince Willem proclaims himself King of the United Kingdom of the Netherlands, the first constitutional monarch in the Netherlands.

The United Kingdom of the Netherlands (Dutch: Verenigd Koninkrijk der Nederlanden; French: Royaume-Uni des Pays-Bas) is the unofficial name given to the Kingdom of the Netherlands as it existed between 1815 and 1839. The United Netherlands was created in the aftermath of the Napoleonic Wars through the fusion of territories that had belonged to the former Dutch Republic, Austrian Netherlands, and Prince-Bishopric of Liège. The polity was a constitutional monarchy, ruled by William I of the House of Orange-Nassau.

The polity collapsed in 1830 with the outbreak of the Belgian Revolution. With the de facto secession of Belgium, the Netherlands was left as a rump state and refused to recognize Belgian independence until 1839 when the Treaty of London was signed, fixing the border between the two states and guaranteeing Belgian independence and neutrality as the Kingdom of Belgium.

1914 Died: Charles Albert Gobat, Swiss lawyer and politician, Nobel Prize laureate (b. 1843)

Charles Albert Gobat (21 May 1843 – 16 March 1914) was a Swiss lawyer, educational administrator, and politician who jointly received the Nobel Peace Prize with Élie Ducommun in 1902 for their leadership of the Permanent International Peace Bureau.

After completing his Ph.D, Gobat began his practicing law in Bern and also lectured on French civil law at Bern University. He then opened an office in Delémont in the canton of Bern, which soon became the leading legal firm of the district.

After practicing law for fifteen years, he became involved in politics and education. In 1882, he was appointed superintendent of public instruction for the canton of Bern, a position he held for thirty years. He was a progressive in educational philosophy and he made many important reforms in the education system. He reformed the system of primary training, obtained increased budgetary support to improve the teacher-pupil ratio, supported the study of living languages, and provided pupils with an alternative to the traditionally narrow classical education by establishing curricula in vocational & professional training.

He won acclaim for his erudite République de Berne et la France pendant les guerres de religion, which was published in 1891 and also widespread recognition for A People's History of Switzerland, which was published in 1900.

He also pursued a career in politics. He was elected to many important positions. He was elected to the Grand Council of Bern in 1882. From 1884 to 1890, he was a member of the Council of States of Switzerland and from 1890 until his death in 1914, he was a member of the National Council, the other chamber of the central Swiss legislative body. In both politics and education, he was a liberal reformer. In 1902, he sponsored several legislation which applied the principle of arbitration to commercial treaties. Gobat worked with the Inter-Parliamentary Union, which was founded by William Randal Cremer, the winner of the Nobel Peace Prize in 1903, in 1889. In 1892 he became the president of the union's fourth conference, which was held in Bern and which founded the Bureau Interparlementaire. He served as general secretary of the bureau, an information office dealing with peace movements, international conciliation, and communication among national parliamentary bodies. The third conference of the union, held in Rome in 1891, established the International Peace Bureau, of which Gobat was director when it was awarded the Nobel peace prize in 1910.

1930 Born: Sully Prudhomme, French poet and critic, Nobel Prize laureate (d. 1907)

René François Armand (Sully) Prudhomme (16 March 1839 – 6 September 1907) was a French poet and essayist. He was the first winner of the Nobel Prize in Literature in 1901.

Born in Paris, Prudhomme originally studied to be an engineer, but turned to philosophy and later to poetry; he declared it as his intention to create scientific poetry for modern times. In character sincere and melancholic, he was linked to the Parnassus school, although, at the same time, his work displays characteristics of its own.

His first collection, Stances et Poèmes ("Stanzas and Poems", 1865), was praised by Sainte-Beuve. It included his most famous poem, Le vase brisé. He published more poetry before the outbreak of the Franco-Prussian War. This war, which he discussed in Impressions de la guerre (1872) and La France (1874), permanently damaged his health.

During his career, Prudhomme gradually shifted from the sentimental style of his first books towards a more personal style which unified the formality of the Parnassus school with his interest in philosophical and scientific subjects. One of his inspirations was clearly Lucretius's De rerum natura, whose first book he translated into verse. His philosophy was expressed in La Justice (1878) and Le Bonheur (1888). The extreme economy of means employed in these poems has, however, usually been judged as compromising their poetical quality without advancing their claims as works of philosophy. He was elected to the Académie française in 1881. Another distinction, Chevalier de la Légion d’honneur, was to follow in 1895.

After, Le Bonheur, Prudhomme turned from poetry to write essays on aesthetics and philosophy. He published two important essays: L'Expression dans les beaux-arts (1884) and Réflexions sur l'art des vers (1892), a series of articles on Blaise Pascal in La Revue des Deux Mondes (1890), and an article on free will (La Psychologie du Libre-Arbitre, 1906) in the Revue de métaphysique et de morale.

At the end of his life, his poor health (which had troubled him ever since 1870) forced him to live almost as a recluse at Châtenay-Malabry, suffering attacks of paralysis while continuing to work on essays. He died suddenly on 6 September 1907, and was buried at Père-Lachaise in Paris.

Here are some events that happened on December 7th. It could be an event or a person that died or was born on that day


1598 Born: Gian Lorenzo Bernini, Italian sculptor and painter (d. 1680)

Gian Lorenzo (or Gianlorenzo) Bernini (7 December 1598 – 28 November 1680) was an Italian sculptor and architect. While a major figure in the world of architecture, he was, also and even more prominently, the leading sculptor of his age, credited with creating the Baroque style of sculpture. As one scholar has commented, "What Shakespeare is to drama, Bernini may be to sculpture: the first pan-European sculptor whose name is instantaneously identifiable with a particular manner and vision, and whose influence was inordinately powerful...." In addition, he was a painter (mostly small canvases in oil) and a man of the theater: he wrote, directed and acted in plays (mostly Carnival satires), for which he designed stage sets and theatrical machinery. He produced designs as well for a wide variety of decorative art objects including lamps, tables, mirrors, and even coaches.

As architect and city planner, he designed secular buildings, churches, chapels, and public squares, as well as massive works combining both architecture and sculpture, especially elaborate public fountains and funerary monuments and a whole series of temporary structures (in stucco and wood) for funerals and festivals. His broad technical versatility, boundless compositional inventiveness and sheer skill in manipulating marble ensured that he would be considered a worthy successor of Michelangelo, far outshining other sculptors of his generation. His talent extended beyond the confines of sculpture to a consideration of the setting in which it would be situated; his ability to synthesize sculpture, painting, and architecture into a coherent conceptual and visual whole has been termed by the late art historian Irving Lavin the "unity of the visual arts".

1732 – The Royal Opera House opens at Covent Garden, London, England.

The Royal Opera House (ROH) is an opera house and major performing arts venue in Covent Garden, central London. The large building is often referred to as simply "Covent Garden", after a previous use of the site of the opera house's original construction in 1732. It is the home of The Royal Opera, The Royal Ballet, and the Orchestra of the Royal Opera House. Originally called the Theatre Royal, it served primarily as a playhouse for the first hundred years of its history. In 1734, the first ballet was presented. A year later, Handel's first season of operas began. Many of his operas and oratorios were specifically written for Covent Garden and had their premieres there.

The current building is the third theatre on the site following disastrous fires in 1808 and 1856. The façade, foyer, and auditorium date from 1858, but almost every other element of the present complex dates from an extensive reconstruction in the 1990s. The main auditorium seats 2,256 people, making it the third largest in London, and consists of four tiers of boxes and balconies and the amphitheatre gallery. The proscenium is 12.20 m wide and 14.80 m high. The main auditorium is a Grade I listed building.

1776 – Gilbert du Motier, Marquis de Lafayette, arranges to enter the American military as a major general.

Marie-Joseph Paul Yves Roch Gilbert du Motier, Marquis de Lafayette (6 September 1757 – 20 May 1834), known in the United States simply as Lafayette, was a French aristocrat and military officer who fought in the American Revolutionary War, commanding American troops in several battles, including the Siege of Yorktown. After returning to France, he was a key figure in the French Revolution of 1789 and the July Revolution of 1830.

Lafayette was born into a wealthy land-owning family in Chavaniac in the province of Auvergne in south central France. He followed the family's martial tradition and was commissioned an officer at age 13. He became convinced that the American revolutionary cause was noble, and he traveled to the New World seeking glory in it. He was made a major general at age 19, but he was initially not given American troops to command. He was wounded during the Battle of Brandywine but still managed to organize an orderly retreat, and he served with distinction in the Battle of Rhode Island. In the middle of the war, he sailed for home to lobby for an increase in French support. He returned to America in 1780 and was given senior positions in the Continental Army. In 1781, troops under his command in Virginia blocked forces led by Cornwallis until other American and French forces could position themselves for the decisive Siege of Yorktown.

Lafayette returned to France and was appointed to the Assembly of Notables in 1787, convened in response to the fiscal crisis. He was elected a member of the Estates General of 1789, where representatives met from the three traditional orders of French society: the clergy, the nobility, and the commoners. After forming the National Constituent Assembly, he helped to write the Declaration of the Rights of Man and of the Citizen with Thomas Jefferson's assistance. This document was inspired by the United States Declaration of Independence and invoked natural law to establish basic principles of the democratic nation-state. He also advocated the end of slavery, in keeping with the philosophy of natural liberty. After the storming of the Bastille, he was appointed commander-in-chief of France's National Guard and tried to steer a middle course through the years of revolution. In August 1792, radical factions ordered his arrest, and he fled into the Austrian Netherlands. He was captured by Austrian troops and spent more than five years in prison.

Lafayette returned to France after Napoleon Bonaparte secured his release in 1797, though he refused to participate in Napoleon's government. After the Bourbon Restoration of 1814, he became a liberal member of the Chamber of Deputies, a position which he held for most of the remainder of his life. In 1824, President James Monroe invited him to the United States as the nation's guest, and he visited all 24 states in the union and met a rapturous reception. During France's July Revolution of 1830, he declined an offer to become the French dictator. Instead, he supported Louis-Philippe as king, but turned against him when the monarch became autocratic. He died on 20 May 1834 and is buried in Picpus Cemetery in Paris, under soil from Bunker Hill. He is sometimes known as "The Hero of the Two Worlds" for his accomplishments in the service of both France and the United States.

1905 Born: Gerard Kuiper, Dutch-American astronomer and academic (d. 1973)

Gerard Peter Kuiper (born Gerrit Pieter Kuiper; December 7, 1905 – December 23, 1973) was a Dutch astronomer, planetary scientist, selenographer, author and professor. He is the eponymous namesake of the Kuiper belt. Kuiper is considered by many to be the father of modern planetary science. As professor at the University of Chicago, he was dissertation advisor to Carl Sagan. In 1958, the two worked on the classified military Project A119, the secret Air Force plan to detonate a nuclear warhead on the Moon.

Kuiper discovered two natural satellites of planets in the Solar System, namely Uranus's satellite Miranda and Neptune's satellite Nereid. In addition, he discovered carbon dioxide in the atmosphere of Mars and the existence of a methane-laced atmosphere above Saturn's satellite Titan in 1944. Kuiper also pioneered airborne infrared observing using a Convair 990 aircraft in the 1960s.

Kuiper spent most of his career at the University of Chicago, but moved to Tucson, Arizona, in 1960 to found the Lunar and Planetary Laboratory at the University of Arizona. Kuiper was the laboratory's director until his death in 1973: while on vacation with his wife in Mexico he had a heart attack. One of the three buildings at Arizona that makes up the LPL is named in his honor.

In the 1950s Kuiper's interdisciplinary collaboration with the geochemist and Nobel Laureate Harold C. Urey to understand the Moon's thermal evolution descended into acrimony, as the two engaged in what became known as the “Hot Moon Cold Moon” controversy. Their falling out, in part a scientific dispute, also reflected the challenge of maintaining professional relationships across overlapping but distinct scientific disciplines.

In the 1960s, Kuiper helped identify landing sites on the Moon for the Apollo program. His earlier work on the Moon included the secret Project A119, the secret Air Force plan to detonate a nuclear warhead on the Moon. Another scientist in the group was Carl Sagan, who was Kuiper's PhD student at the time of the project.

Kuiper discovered several binary stars which received "Kuiper numbers" to identify them, such as KUI 79.

1906 Died: Élie Ducommun, Swiss journalist and educator, Nobel Prize laureate (b. 1833)

Élie Ducommun (19 February 1833, Geneva – 7 December 1906, Bern) was a Swiss peace activist. He was a Nobel laureate, awarded the 1902 Nobel Peace Prize, which he shared with Charles Albert Gobat.

Born in Geneva, he worked as a tutor, language teacher, journalist and a translator for the Swiss federal Chancellery (1869–1873).

In 1867 he helped to found the Ligue de la paix et de la liberté (League of Peace and Freedom), though he continued working at other positions, including secretary for the Jura-Simplon Steel Company from 1873 to 1891. That year, he was appointed director of the newly formed Bureau international de la paix (International Peace Office), the first non-governmental international peace organization, based in Bern. He refused to accept a salary for the position, stating that he wished to serve in this capacity solely for reasons of idealism.

His keen organizational skills ensured the group's success. He was awarded in the Nobel Peace Prize in 1902, and served as director of the organization until his death in 1906.

Here are some events that happened on November 12th. It could be an event or a person that died or was born on that day

1729 Born: Louis Antoine de Bougainville, French admiral and explorer (d. 1811)

Louis-Antoine, Comte de Bougainville (12 November 1729 – 31 August 1811) was a French admiral and explorer. A contemporary of the British explorer James Cook, he took part in the Seven Years' War in North America and the American Revolutionary War against Britain. Bougainville later gained fame for his expeditions, including circumnavigation of the globe in a scientific expedition in 1763, the first recorded settlement on the Falkland Islands, and voyages into the Pacific Ocean. Bougainville Island of Papua New Guinea as well as the Bougainvillea flower were named after him.

In 1771, Bougainville published his travel log from the expedition under the title Le voyage autour du monde, par la frégate La Boudeuse, et la flûte L'Étoile (a.k.a. Voyage autour du monde and A Voyage Around the World). The book describes the geography, biology and anthropology of Argentina (then a Spanish colony), Patagonia, Tahiti and Indonesia (then a Dutch colony). The book was a sensation, especially the description of Tahitian society. Bougainville described it as an earthly paradise where men and women lived in blissful innocence, far from the corruption of civilization.

After an interval of several years, Bougainville again accepted a naval command and saw much active service between 1779 and 1782 during the American Revolutionary War, when France was as an ally of the rebels. He played a crucial part in the French victory at the Battle of the Chesapeake, which led to the eventual defeat of Great Britain.

Returning to Paris, he was one of the founding members of the Bureau des Longitudes. In 1799, the Consul Napoleon made him a senator. He died in Paris on 31 August 1811.

1842 Born: John William Strutt, 3rd Baron Rayleigh, English physicist and academic, Nobel Prize laureate (d. 1919)

John William Strutt, 3rd Baron Rayleigh(12 November 1842 – 30 June 1919), was a British scientist who made extensive contributions to both theoretical and experimental physics. He spent all of his academic career at the University of Cambridge. Among many honors, he received the 1904 Nobel Prize in Physics "for his investigations of the densities of the most important gases and for his discovery of argon in connection with these studies." He served as President of the Royal Society from 1905 to 1908 and as Chancellor of the University of Cambridge from 1908 to 1919.

Rayleigh provided the first theoretical treatment of the elastic scattering of light by particles much smaller than the light's wavelength, a phenomenon now known as "Rayleigh scattering", which notably explains why the sky is blue. He studied and described transverse surface waves in solids, now known as "Rayleigh waves". He contributed extensively to fluid dynamics, with concepts such as the Rayleigh number (a dimensionless number associated with natural convection), Rayleigh flow, the Rayleigh–Taylor instability, and Rayleigh's criterion for the stability of Taylor–Couette flow. He also formulated the circulation theory of aerodynamic lift. In optics, Rayleigh proposed a well known criterion for angular resolution. His derivation of the Rayleigh–Jeans law for classical black-body radiation later played an important role in the birth of quantum mechanics (see Ultraviolet catastrophe). Rayleigh's textbook The Theory of Sound (1877) is still used today by acousticians and engineers.

1955 Died: Tin Ujevic, Croatian poet and translator (b. 1891)

Augustin Josip "Tin" Ujević (5 July 1891 – 12 November 1955) was a Croatian poet, considered by many to be the greatest poet in 20th century Croatian literature.

From 1921, he ceased to sign his name as Augustin, thereafter using the signature Tin Ujević

In addition to his poetry, Tin Ujević also wrote essays, short stories, serials (feuilletons), studies on foreign and domestic authors, and he translated philosophical discussions from many foreign languages. He translated numerous works of poetry, novels and short stories into Croatian (Edgar Allan Poe, Walt Whitman, Marcel Proust, Joseph Conrad, Benvenuto Cellini, George Meredith, Emile Verhaeren, Arthur Rimbaud, André Gide, among others).

He wrote more than ten books of essays, poetry in prose and meditations — but his enduring strength lies chiefly in his poetic works. At first a follower of Silvije Strahimir Kranjčević and more especially A.G. Matoš, Ujević soon moved on and developed his own independent voice.

He preferred the French and American modernists such as Charles Baudelaire, Arthur Rimbaud and Walt Whitman, whose work he translated. His first collections Lelek sebra, and Kolajna, inspired by his years in Paris, are considered the peak of modern Croatian lyrical poetry.

From those original first books grew a body of work that is a classic of Croatian literature, and according to the British poet Clive Wilmer, "Tin Ujević was one of the last masters of European Symbolism". Poet and writer Anne Stevenson says his "melancholy, turn-of-the-century lyricism" is comparable to that of Thomas Hardy, of Edward Thomas, and of early Yeats".

British poet Richard Berengarten, who has translated some of Ujević's best works into English, writes

"Although Tin's major achievement is as a lyricist, his oeuvre is much broader than lyric alone. He was a writer of profound and discerning intellect, broad and capacious interests, inquisitive appetite and eclectic range."


Ujević died on 12 November 1955 and is buried at Mirogoj Cemetery in Zagreb.

1918 – Austria becomes a republic. After the proclamation, a coup attempt by the communist Red Guard was defeated by the social-democratic Volkswehr.

The First Austrian Republic (German: Republik Österreich) was created after the signing of the Treaty of Saint-Germain-en-Laye on 10 September 1919—the settlement after the end of World War I which ended the Habsburg rump state of Republic of German-Austria—and ended with the establishment of the Austrofascist Federal State of Austria based upon a dictatorship of Engelbert Dollfuss and the Fatherland's Front in 1934. The Republic's constitution was enacted in 1 October 1920 and amended on 7 December 1929. The republican period was increasingly marked by violent strife between those with left-wing and right-wing views, leading to the July Revolt of 1927 and the Austrian Civil War of 1934.

On 11 November 1918, Emperor Charles I in all but name abdicated, by relinquishing his right to take part in Austrian affairs of state.

The next day, 12 November, the National Assembly officially declared German-Austria a republic and named Social Democrat Karl Renner as provisional chancellor. On the same day it drafted a provisional constitution that stated that "German-Austria is a democratic republic" and "German-Austria is an integral part of the German republic"  The latter provision reflected the deputies' view that felt that Austria would lose so much territory in any peace settlement that it would no longer be economically and politically viable as a separate state, and the only course was union with Germany. This was enforced by the refusal of Hungary to sell grain and of Czechoslovakia to sell coal to Austria-Germany.

As the Empire collapsed and a ceasefire was announced, the Provisional Assembly sought to forestall socialist revolution by organizing a coalition government led by the minority Social Democrats. Karl Renner became Chancellor and Victor Adler became Foreign Minister. The Social Democrats co-opted newly created soldier and worker councils and used their control over labor unions to implement social policies that blunted the socialist appeal.

October 9 in stamps Restauration, Alexander I of Yugoslavia, astronomical clock, Schindler,Zeeman, Hermann Emil Fischer

Here are some events that happened on October 9th. It could be an event or a person that died or was born on that day


1410 – The first known mention of the Prague astronomical clock.

The Prague Astronomical Clock, or Prague Orloj (Czech: Pražský orloj [praʃskiː orloj]), is a medieval astronomical clock located in Prague, the capital of the Czech Republic.

The clock was first installed in 1410, making it the third-oldest astronomical clock in the world and the oldest clock still operating.

The oldest part of the Orloj, the mechanical clock and astronomical dial, dates back to 1410 when it was made by clockmaker Mikuláš of Kadaň and Jan Šindel, then later a professor of mathematics and astronomy at Charles University. The first recorded mention of the clock was on 9 October 1410. Later, presumably around 1490, the calendar dial was added and the clock facade was decorated with gothic sculptures.

Formerly, it was believed that the Orloj was constructed in 1490 by clockmaster Jan Růže (also called Hanuš); this is now known to be a historical mistake. A legend, recounted by Alois Jirásek, has it that the clockmaker Hanuš was blinded on the order of the Prague Councillors so that he could not repeat his work; in turn, he disabled the clock, and no one was able to repair it for the next hundred years.

In 1552 it was repaired by Jan Taborský (ca 1500–1572), master clockmaker of Klokotská Hora, who also wrote a report of the clock where he mentioned Hanuš as the maker of this clock. This mistake, corrected by Zdeněk Horský, was due to an incorrect interpretation of records from the period. The mistaken assumption that Hanuš was the maker is probably connected with his reconstruction of the Old Town Hall in the years 1470–1473. The clock stopped working many times in the centuries after 1552, and was repaired many times. The legend was used as the main plot in the animated movie Goat story - The Old Prague Legends

In 1629 or 1659 wooden statues were added, and figures of the Apostles were added after a major repair in 1787–1791. During the next major repair in the years 1865–1866 the golden figure of a crowing rooster was added.

1825 – Restauration arrives in New York Harbor from Norway, the first organized immigration from Norway to the United States.

On what is considered the first organized emigration from Norway to the United States, Restauration set sail from Stavanger on July 4, 1825, with 52 people aboard, many of them Norwegian Quakers. Probably many of this group belonged to a similar local movement, the Haugeans, a Lutheran sect which derived its name from Hans Nielsen Hauge. The group, led by Cleng Peerson, landed in New York City on October 9, 1825, after a three-month voyage. The voyage is described in Ole Rynning's Amerika-boka (The America Book, 1838).

For a vessel of her size Restauration had far more passengers on board than were allowed by American law. This resulted in a severe fine, confiscation of the ship and the arrest of the captain, L. O. Helland. The situation was solved when President John Quincy Adams pardoned the captain on 15 November, released him and the ship, and rescinded the fine. The people who made this voyage, who are sometimes referred to as the "Sloopers," moved onward to their first settlement in Kendall, Orleans County, New York

The United States Post Office issued two stamps commemorate the 1825 arrival. The 2-cent stamp has for its central design a ship representing Restauration. The illustration on the two cent stamp is an artist's rendition of what Restauration probably looked like based on a drawing of its sister ship.

The 5-cent stamp has for its central design a Viking ship. This design is from a photograph of Viking which sailed from Norway to Chicago for the Columbian Exposition of 1893. The design on the 5-cent stamp was from a photograph of an exact size replica of Viking. A flag of the United States is seen waving from the bow of the ship. That ship was a replica of the Gokstad ship on display in the Viking Ship Museum in Oslo.

In 1975, in honor of the sesquicentennial of the arrival of Restauration, Cleng Peerson was depicted on a Norwegian NOK 1.40 postage stamp.

1852  Born: Hermann Emil Fischer, German chemist and academic, Nobel Prize laureate (d. 1919)

Hermann Emil Louis Fischer (9 October 1852 – 15 July 1919) was a German chemist and 1902 recipient of the Nobel Prize in Chemistry. He discovered the Fischer esterification. He also developed the Fischer projection, a symbolic way of drawing asymmetric carbon atoms. He also hypothesized lock and key mechanism of enzyme action. He never used his first given name, and was known throughout his life simply as Emil Fischer.

In 1875, the year following his engagement with von Baeyer, he published his discovery of the organic derivatives of a new compound of hydrogen and nitrogen, hydrazine. He investigated their derivatives, establishing their relation to the diazo compounds, and he noted the readiness with which they entered into combination with other substances, giving origin to a wealth of hitherto unknown compounds. Of such condensation products undoubtedly the most important are the hydrazones, which result from the interaction with aldehydes and ketones. His observations, published in 1886, that such hydrazones, by treatment with hydrochloric acid or zinc chloride, yielded derivatives of indole, the parent substance of indigo, were a confirmation of the views advanced by von Baeyer on the subject of indigo and the many substances related to it.

He next turned to the fuchsine (then called "rosaniline") magenta dyes, and in collaboration with his cousin Otto Fischer, he published papers in 1878 and 1879 which established that these dyes were derivatives of triphenylmethane. Emil Fischer's next research was concerned with compounds related to uric acid. Here the ground had been broken by von Baeyer, but Fischer greatly advanced the field of knowledge of the purines. In 1881 and 1882 he published papers which established the formulae of uric acid, xanthine, caffeine (achieving the first synthesis), theobromine and some other compounds of this group. After purine itself was isolated, a variety of derivatives were prepared, some of which were patented in view of possible therapeutical applications.

Fischer is particularly noted for his work on sugars. Among his early discoveries related to hydrazine was that phenylhydrazine reacted with sugars to form substances which he named osazones, and which, being highly crystalline and readily formed, served to identify such carbohydrates more definitely than had been previously possible. Later, among other work, he is noted for the organic synthesis of D-(+)-glucose. He showed how to deduce the formulae of the 16 stereoisomeric glucoses, and prepared several stereoisomerides, helping to confirm the Le Bel–Van 't Hoff rule of the asymmetric carbon atom.

In the field of enzymology, Fischer is known for his proposal of "the lock and key" model as a mechanism of substrate binding.

Fischer was also instrumental in the discovery of barbiturates, a class of sedative drugs used for insomnia, epilepsy, anxiety, and anesthesia. Along with the physician Josef von Mering, he helped to launch the first barbiturate sedative, barbital, in 1904. He next carried out pioneering work on proteins. By the introduction of new methods, he succeeded in breaking down the complex albumins into amino acids and other nitrogenous compounds, the constitutions of most of which were known, and by bringing about the recombination of these units, he prepared synthetic peptides which approximated to the natural products. His researches made from 1899 to 1906 were published in 1907 with the title Untersuchungen über Aminosauren, Polypeptides und Proteine.

In 1897 he put forward the idea to create the International Atomic Weights Commission. Fischer was elected a Foreign Member of the Royal Society (ForMemRS) in 1899. He was awarded the 1902 Nobel Prize in chemistry "in recognition of the extraordinary services he has rendered by his work on sugar and purine syntheses."

Many names of chemical reactions and concepts are named after him:

• Fischer indole synthesis
• Fischer projection
• Fischer oxazole synthesis
• Fischer peptide synthesis
• Fischer phenylhydrazine and oxazone reaction
• Fischer–Speier esterification
• Fischer glycosidation
• Kiliani–Fischer synthesis

1934 Died: Alexander I of Yugoslavia, King of Yugoslavia also known as Alexander the Unifier (b. 1888)

Alexander I (16 December 1888 – 9 October 1934), also known as Alexander the Unifier served as a prince regent of the Kingdom of Serbia from 1914 and later became King of Yugoslavia from 1921 to 1934 (prior to 1929 the state was known as the Kingdom of Serbs, Croats and Slovenes). He was assassinated in Marseille, France, by Bulgarian terrorist Vlado Chernozemski during a state visit.

1953 Died: Pieter Zeeman, Dutch physicist and academic, Nobel Prize laureate (b. 1865 )

Pieter Zeeman (25 May 1865 – 9 October 1943) was a Dutch physicist who shared the 1902 Nobel Prize in Physics with Hendrik Lorentz for his discovery of the Zeeman effect

After Zeeman passed the qualification exams in 1885, he studied physics at the University of Leiden under Kamerlingh Onnes and Hendrik Lorentz. In 1890, even before finishing his thesis, he became Lorentz's assistant. This allowed him to participate in a research programme on the Kerr effect. In 1893 he submitted his doctoral thesis on the Kerr effect, the reflection of polarized light on a magnetized surface. After obtaining his doctorate he went for half a year to Friedrich Kohlrausch's institute in Strasbourg. In 1895, after returning from Strasbourg, Zeeman became Privatdozent in mathematics and physics in Leiden. The same year he married Johanna Elisabeth Lebret (1873–1962); they had three daughters and one son.

In 1896, shortly before moving from Leiden to Amsterdam, he measured the splitting of spectral lines by a strong magnetic field, a discovery now known as the Zeeman effect, for which he won the 1902 Nobel Prize in Physics. This research involved an investigation of the effect of magnetic fields on a light source. He discovered that a spectral line is split into several components in the presence of a magnetic field. Lorentz first heard about Zeeman's observations on Saturday 31 October 1896 at the meeting of the Royal Netherlands Academy of Arts and Sciences in Amsterdam, where these results were communicated by Kamerlingh Onnes. The next Monday, Lorentz called Zeeman into his office and presented him with an explanation of his observations, based on Lorentz's theory of electromagnetic radiation.

The importance of Zeeman's discovery soon became apparent. It confirmed Lorentz's prediction about the polarization of light emitted in the presence of a magnetic field. Thanks to Zeeman's work it became clear that the oscillating particles that according to Lorentz were the source of light emission were negatively charged, and were a thousandfold lighter than the hydrogen atom. This conclusion was reached well before J. J. Thomson's discovery of the electron. The Zeeman effect thus became an important tool for elucidating the structure of the atom.

In 1898 Zeeman was elected to membership of the Royal Netherlands Academy of Arts and Sciences in Amsterdam, and he served as its secretary from 1912 to 1920. He won the Henry Draper Medal in 1921, and several other awards and Honorary degrees. Zeeman was elected a Foreign member of the Royal Society (ForMemRS) in 1921. He retired as a professor in 1935.

Zeeman died on 9 October 1943 in Amsterdam, and was buried in Haarlem.

1974 Died: Oskar Schindler, Czech-German businessman (b. 1908)

Oskar Schindler (28 April 1908 – 9 October 1974) was a German industrialist and a member of the Nazi Party who is credited with saving the lives of 1,200 Jews during the Holocaust by employing them in his enamelware and ammunitions factories in occupied Poland and the Protectorate of Bohemia and Moravia. He is the subject of the 1982 novel Schindler's Ark and its 1993 film adaptation, Schindler's List, which reflected his life as an opportunist initially motivated by profit, who came to show extraordinary initiative, tenacity, courage, and dedication to save the lives of his Jewish employees.

In 1939, Schindler acquired an enamelware factory in Kraków, Poland, which employed at the factory's peak in 1944 about 1,750 workers, of whom 1,000 were Jews. His Abwehr connections helped Schindler protect his Jewish workers from deportation and death in the Nazi concentration camps. As time went on, Schindler had to give Nazi officials ever larger bribes and gifts of luxury items obtainable only on the black market to keep his workers safe.

Schindler moved to West Germany after the war, where he was supported by assistance payments from Jewish relief organisations. After receiving a partial reimbursement for his wartime expenses, he moved with his wife Emilie to Argentina, where they took up farming. When he went bankrupt in 1958, Schindler left his wife and returned to Germany, where he failed at several business ventures and relied on financial support from Schindlerjuden ("Schindler Jews")—the people whose lives he had saved during the war. He died on 9 October 1974 in Hildesheim, Germany, and was buried in Jerusalem on Mount Zion, the only member of the Nazi Party to be honoured in this way. He and his wife Emilie were named Righteous Among the Nations by the Israeli government in 1993.
