Here are some events that happened on March 1st. It could be an event or a person that died or was born on that day


1872 – Yellowstone National Park is established as the world's first national park.

Yellowstone National Park is an American national park located mostly in Wyoming, with small sections in Montana and Idaho. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular features. It has many types of ecosystem, but the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.

Native Americans have lived in the Yellowstone region for at least 11,000 years. Aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park originally fell under the jurisdiction of the Secretary of the Interior, the first being Columbus Delano. However, the U.S. Army was subsequently commissioned to oversee management of Yellowstone for a 30-year period between 1886 and 1916. In 1917, administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than a thousand archaeological sites.

Yellowstone National Park spans an area of 3,468.4 square miles (8,983 km2), comprising lakes, canyons, rivers and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered a dormant volcano. It has erupted with tremendous force several times in the last two million years. Half of the world's geysers and hydrothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth's northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.

Hundreds of species of mammals, birds, fish, and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous megafauna location in the contiguous United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one third of the park was burnt. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.

1896 – Henri Becquerel discovers radioactive decay.

Antoine Henri Becquerel (15 December 1852 – 25 August 1908) was a French engineer, physicist, Nobel laureate, and the first person to discover evidence of radioactivity. For work in this field he, along with Marie Skłodowska-Curie (Marie Curie) and Pierre Curie, received the 1903 Nobel Prize in Physics. The SI unit for radioactivity, the becquerel (Bq), is named after him.

1911 Died: Jacobus Henricus van 't Hoff, Dutch chemist and academic, Nobel Prize laureate (b. 1852)

Jacobus Henricus "Henry" van 't Hoff Jr. (30 August 1852 – 1 March 1911) was a Dutch physical chemist. A highly influential theoretical chemist of his time, Van 't Hoff was the first winner of the Nobel Prize in Chemistry. His pioneering work helped found the modern theory of chemical affinity, chemical equilibrium, chemical kinetics, and chemical thermodynamics. In his 1874 pamphlet Van 't Hoff formulated the theory of the tetrahedral carbon atom and laid the foundations of stereochemistry. In 1875, he predicted the correct structures of allenes and cumulenes as well as their axial chirality. He is also widely considered one of the founders of physical chemistry as the discipline is known today.

Van 't Hoff earned his earliest reputation in the field of organic chemistry. In 1874, he accounted for the phenomenon of optical activity by assuming that the chemical bonds between carbon atoms and their neighbors were directed towards the corners of a regular tetrahedron. This three-dimensional structure accounted for the isomers found in nature. He shares credit for this with the French chemist Joseph Le Bel, who independently came up with the same idea.

Three months before his doctoral degree was awarded, Van 't Hoff published this theory, which today is regarded as the foundation of stereochemistry, first in a Dutch pamphlet in the fall of 1874, and then in the following May in a small French book entitled La chimie dans l'espace. A German translation appeared in 1877, at a time when the only job Van 't Hoff could find was at the Veterinary School in Utrecht. In these early years his theory was largely ignored by the scientific community, and was sharply criticized by one prominent chemist.

In 1884, Van 't Hoff published his research on chemical kinetics, titled Études de Dynamique chimique ("Studies in Chemical Dynamics"), in which he described a new method for determining the order of a reaction using graphics and applied the laws of thermodynamics to chemical equilibria. He also introduced the modern concept of chemical affinity. In 1886, he showed a similarity between the behaviour of dilute solutions and gases. In 1887, he and German chemist Wilhelm Ostwald founded an influential scientific magazine named Zeitschrift für physikalische Chemie ("Journal of Physical Chemistry"). He worked on Svante Arrhenius's theory of the dissociation of electrolytes and in 1889 provided physical justification for the Arrhenius equation. In 1896, he became a professor at the Prussian Academy of Sciences in Berlin. His studies of the salt deposits at Stassfurt were an important contribution to Prussia's chemical industry.

Van 't Hoff became a lecturer in chemistry and physics at the Veterinary College in Utrecht. He then worked as a professor of chemistry, mineralogy, and geology at the University of Amsterdam for almost 18 years before eventually becoming the chairman of the chemistry department. In 1896, Van 't Hoff moved to Germany, where he finished his career at the University of Berlin in 1911. In 1901, he received the first Nobel Prize in Chemistry for his work with solutions. His work showed that very dilute solutions follow mathematical laws that closely resemble the laws describing the behavior of gases.

1936 – The Hoover Dam is completed.

Hoover Dam is a concrete arch-gravity dam in the Black Canyon of the Colorado River, on the border between the U.S. states of Nevada and Arizona. It was constructed between 1931 and 1936 during the Great Depression and was dedicated on September 30, 1935, by President Franklin D. Roosevelt. Its construction was the result of a massive effort involving thousands of workers, and cost over one hundred lives. Originally known as Boulder Dam from 1933, it was officially renamed Hoover Dam, for President Herbert Hoover, by a joint resolution of Congress in 1947.

Since about 1900, the Black Canyon and nearby Boulder Canyon had been investigated for their potential to support a dam that would control floods, provide irrigation water and produce hydroelectric power. In 1928, Congress authorized the project. The winning bid to build the dam was submitted by a consortium called Six Companies, Inc., which began construction of the dam in early 1931. Such a large concrete structure had never been built before, and some of the techniques were unproven. The torrid summer weather and lack of facilities near the site also presented difficulties. Nevertheless, Six Companies turned the dam over to the federal government on March 1, 1936, more than two years ahead of schedule.

Hoover Dam impounds Lake Mead, the largest reservoir in the United States by volume (when it is full). The dam is located near Boulder City, Nevada, a municipality originally constructed for workers on the construction project, about 30 mi (48 km) southeast of Las Vegas, Nevada. The dam's generators provide power for public and private utilities in Nevada, Arizona, and California. Hoover Dam is a major tourist attraction; nearly a million people tour the dam each year. The heavily traveled U.S. Route 93 (US 93) ran along the dam's crest until October 2010, when the Hoover Dam Bypass opened.

1938 Died: Gabriele D'Annunzio, Italian journalist and politician (b. 1863)

General Gabriele D'Annunzio, Prince of Montenevoso, Duke of Gallese (12 March 1863 – 1 March 1938), sometimes spelled d'Annunzio, was an Italian poet, journalist, playwright and soldier during World War I. He occupied a prominent place in Italian literature from 1889 to 1910 and later political life from 1914 to 1924. He was often referred to under the epithets Il Vate ("the Poet") or Il Profeta ("the Prophet").

D'Annunzio was associated with the Decadent movement in his literary works, which interplayed closely with French Symbolism and British Aestheticism. Such works represented a turn against the naturalism of the preceding romantics and was both sensuous and mystical. He came under the influence of Friedrich Nietzsche which would find outlets in his literary and later political contributions. His affairs with several women, including Eleonora Duse and Luisa Casati, received public attention.

During the First World War, perception of D'Annunzio in Italy transformed from literary figure into a national war hero. He was associated with the elite Arditi storm troops of the Italian Army and took part in actions such as the Flight over Vienna. As part of an Italian nationalist reaction against the Paris Peace Conference, he set up the short-lived Italian Regency of Carnaro in Fiume with himself as Duce. The constitution made "music" the fundamental principle of the state and was corporatist in nature. Though D'Annunzio never declared himself a fascist, he has been described as the forerunner of Italian fascism as his ideas and aesthetics influenced it and the style of Benito Mussolini.

Here are some events that happened on February 13th. It could be an event or a person that died or was born on that day


1633 – Galileo Galilei arrives in Rome for his trial before the Inquisition.

Galileo di Vincenzo Bonaulti de Galilei (15 February 1564 – 8 January 1642) was an Italian astronomer, physicist and engineer, sometimes described as a polymath, from Pisa. Galileo has been called the "father of observational astronomy", the "father of modern physics", the "father of the scientific method", and the "father of modern science".

Galileo studied speed and velocity, gravity and free fall, the principle of relativity, inertia, projectile motion and also worked in applied science and technology, describing the properties of pendulums and "hydrostatic balances", inventing the thermoscope and various military compasses, and using the telescope for scientific observations of celestial objects. His contributions to observational astronomy include the telescopic confirmation of the phases of Venus, the observation of the four largest satellites of Jupiter, the observation of Saturn's rings, and the analysis of sunspots.

Galileo's championing of heliocentrism and Copernicanism was controversial during his lifetime, when most subscribed to geocentric models such as the Tychonic system. He met with opposition from astronomers, who doubted heliocentrism because of the absence of an observed stellar parallax. The matter was investigated by the Roman Inquisition in 1615, which concluded that heliocentrism was "foolish and absurd in philosophy, and formally heretical since it explicitly contradicts in many places the sense of Holy Scripture".

Galileo later defended his views in Dialogue Concerning the Two Chief World Systems (1632), which appeared to attack Pope Urban VIII and thus alienated him and the Jesuits, who had both supported Galileo up until this point. He was tried by the Inquisition, found "vehemently suspect of heresy", and forced to recant. He spent the rest of his life under house arrest. While under house arrest, he wrote Two New Sciences, in which he summarized work he had done some forty years earlier on the two sciences now called kinematics and strength of materials.

1787 Died: Roger Joseph Boscovich, Croatian physicist, astronomer, mathematician, and philosopher (b. 1711)

Roger Joseph Boscovich (18 May 1711 – 13 February 1787) was a physicist, astronomer, mathematician, philosopher, diplomat, poet, theologian, Jesuit priest, and a polymath from the Republic of Ragusa (modern-day Dubrovnik, Croatia). He studied and lived in Italy and France where he also published many of his works.

Boscovich produced a precursor of atomic theory and made many contributions to astronomy, including the first geometric procedure for determining the equator of a rotating planet from three observations of a surface feature and for computing the orbit of a planet from three observations of its position. In 1753 he also discovered the absence of atmosphere on the Moon.

1883 Died: Richard Wagner, German composer (b. 1813)

Wilhelm Richard Wagner (22 May 1813 – 13 February 1883) was a German composer, theatre director, polemicist, and conductor who is chiefly known for his operas (or, as some of his mature works were later known, "music dramas"). Unlike most opera composers, Wagner wrote both the libretto and the music for each of his stage works. Initially establishing his reputation as a composer of works in the romantic vein of Carl Maria von Weber and Giacomo Meyerbeer, Wagner revolutionised opera through his concept of the Gesamtkunstwerk ("total work of art"), by which he sought to synthesise the poetic, visual, musical and dramatic arts, with music subsidiary to drama. He described this vision in a series of essays published between 1849 and 1852. Wagner realised these ideas most fully in the first half of the four-opera cycle Der Ring des Nibelungen (The Ring of the Nibelung).

His compositions, particularly those of his later period, are notable for their complex textures, rich harmonies and orchestration, and the elaborate use of leitmotifs—musical phrases associated with individual characters, places, ideas, or plot elements. His advances in musical language, such as extreme chromaticism and quickly shifting tonal centres, greatly influenced the development of classical music. His Tristan und Isolde is sometimes described as marking the start of modern music.

Wagner had his own opera house built, the Bayreuth Festspielhaus, which embodied many novel design features. The Ring and Parsifal were premiered here and his most important stage works continue to be performed at the annual Bayreuth Festival, run by his descendants. His thoughts on the relative contributions of music and drama in opera were to change again, and he reintroduced some traditional forms into his last few stage works, including Die Meistersinger von Nürnberg (The Mastersingers of Nuremberg).

Until his final years, Wagner's life was characterised by political exile, turbulent love affairs, poverty and repeated flight from his creditors. His controversial writings on music, drama and politics have attracted extensive comment, notably, since the late 20th century, where they express antisemitic sentiments. The effect of his ideas can be traced in many of the arts throughout the 20th century; his influence spread beyond composition into conducting, philosophy, literature, the visual arts and theatre.

1990 – German reunification: An agreement is reached on a two-stage plan to reunite Germany.

German reunification (German: Deutsche Wiedervereinigung) was the process in 1990 in which the German Democratic Republic became part of the Federal Republic of Germany to form the reunited nation of Germany, as provided by Article 23 of the Federal Republic of Germany's then constitution (Grundgesetz). The end of the unification process is officially referred to as German unity (German: Deutsche Einheit), celebrated each year on 3 October as German Unity Day (German: Tag der deutschen Einheit). Berlin was reunited into a single city, and was once again designated as the capital of united Germany.

The East German government started to falter in May 1989, when the removal of Hungary's border fence with Austria opened a hole in the Iron Curtain. It caused an exodus of thousands of East Germans fleeing to West Germany and Austria via Hungary. The Peaceful Revolution, a series of protests by East Germans, led to the GDR's first free elections on 18 March 1990, and to the negotiations between the GDR and FRG that culminated in a Unification Treaty. Other negotiations between the GDR and FRG and the four occupying powers produced the so-called "Two Plus Four Treaty" (Treaty on the Final Settlement with Respect to Germany) granting full sovereignty to a unified German state, whose two parts were previously bound by a number of limitations stemming from their post-World War II status as occupied regions.

The 1945 Potsdam Agreement had specified that a full peace treaty concluding World War II, including the exact delimitation of Germany's postwar boundaries, required to be "accepted by the Government of Germany when a government adequate for the purpose is established." The Federal Republic had always maintained that no such government could be said to have been established until East and West Germany had been united within a free democratic state; but in 1990 a range of opinions continued to be maintained over whether a unified West Germany, East Germany, and Berlin could be said to represent "Germany as a whole" for this purpose. The key question was whether a Germany that remained bounded to the east by the Oder–Neisse line could act as a "united Germany" in signing the peace treaty without qualification. Under the "Two Plus Four Treaty" both the Federal Republic and the Democratic Republic committed themselves and their unified continuation to the principle that their joint pre-1990 boundaries constituted the entire territory that could be claimed by a Government of Germany, and hence that there were no further lands outside those boundaries that were parts of Germany as a whole.

The post-1990 united Germany is not a successor state, but an enlarged continuation of the former West Germany. As such, the enlarged Federal Republic of Germany retained the West German seats in international organizations including the European Community (later the European Union) and NATO, while relinquishing membership in the Warsaw Pact and other international organizations to which only East Germany belonged. It also maintains the United Nations membership of the old West Germany.

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


1763 Died: Pierre de Marivaux, French author and playwright (b. 1688)

Pierre Carlet de Chamblain de Marivaux (4 February 1688 – 12 February 1763), commonly referred to as Marivaux, was a French novelist and dramatist.

He is considered one of the most important French playwrights of the 18th century, writing numerous comedies for the Comédie-Française and the Comédie-Italienne of Paris. His most important works are Le Triomphe de l'amour, Le Jeu de l'amour et du hasard and Les Fausses Confidences. He also published a number of essays and two important but unfinished novels, La Vie de Marianne and Le Paysan parvenu.

1809 Born: Charles Darwin, English geologist and theorist (d. 1882)

Charles Robert Darwin (12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species. By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact. However, many favoured competing explanations which gave only a minor role to natural selection, and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.

Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. Studies at the University of Cambridge (Christ's College) encouraged his passion for natural science. His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's conception of gradual geological change, and publication of his journal of the voyage made him famous as a popular author.

Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations, and in 1838 conceived his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay that described the same idea, prompting immediate joint publication of both of their theories. Darwin's work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature. In 1871 he examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex, followed by The Expression of the Emotions in Man and Animals (1872). His research on plants was published in a series of books, and in his final book, The Formation of Vegetable Mould, through the Actions of Worms (1881), he examined earthworms and their effect on soil.

1809 Born: Abraham Lincoln, American lawyer and politician, 16th President of the United States (assassinated in 1865)

Abraham Lincoln (February 12, 1809 – April 15, 1865) was an American statesman and lawyer who served as the 16th president of the United States from March 1861 until his assassination in April 1865. Lincoln led the nation through the American Civil War, its bloodiest war and its greatest moral, constitutional, and political crisis. He preserved the Union, abolished slavery, strengthened the federal government, and modernized the U.S. economy.

Born in Kentucky, Lincoln grew up on the frontier in a poor family. Self-educated, he became a lawyer, Whig Party leader, Illinois state legislator and Congressman. In 1849, he left government to resume his law practice, but angered by the success of Democrats in opening the prairie lands to slavery, reentered politics in 1854. He became a leader in the new Republican Party and gained national attention in 1858 for debating national Democratic leader Stephen A. Douglas in the 1858 Illinois Senate campaign. He then ran for President in 1860, sweeping the North and winning. Southern pro-slavery elements took his win as proof that the North was rejecting the constitutional rights of Southern states to practice slavery. They began the process of seceding from the union. To secure its independence, the new Confederate States of America fired on Fort Sumter, one of the few U.S. forts in the South. Lincoln called up volunteers and militia to suppress the rebellion and restore the Union.

As the leader of the moderate faction of the Republican Party, Lincoln confronted Radical Republicans, who demanded harsher treatment of the South; War Democrats, who rallied a large faction of former opponents into his camp; anti-war Democrats (called Copperheads), who despised him; and irreconcilable secessionists, who plotted his assassination. Lincoln fought the factions by pitting them against each other, by carefully distributing political patronage, and by appealing to the American people. His Gettysburg Address became an iconic call for nationalism, republicanism, equal rights, liberty, and democracy. He suspended habeas corpus, and he averted British intervention by defusing the Trent Affair. Lincoln closely supervised the war effort, including the selection of generals and the naval blockade that shut down the South's trade. As the war progressed, he maneuvered to end slavery, issuing the Emancipation Proclamation of 1863; ordering the Army to protect escaped slaves, encouraging border states to outlaw slavery, and pushing through Congress the Thirteenth Amendment to the United States Constitution, which outlawed slavery across the country.

Lincoln managed his own re-election campaign. He sought to reconcile his damaged nation by avoiding retribution against the secessionists. A few days after the Battle of Appomattox Court House, he was shot by John Wilkes Booth, an actor and Confederate sympathizer, on April 14, 1865, and died the following day. Abraham Lincoln is remembered as the United States' martyr hero. He is consistently ranked both by scholars and the public as among the greatest U.S. presidents.

1877 Born: Louis Renault, French engineer and businessman, co-founded Renault (d. 1944)

Louis Renault (12 February 1877 – 24 October 1944) was a French industrialist, one of the founders of Renault and a pioneer of the automobile industry.

Renault built one of France's largest automobile manufacturing concerns, which bears his name to this day. During World War I his factories contributed massively to the war effort notably so by the creation and manufacture of the first effective tank: the Renault FT tank.

Accused of collaborating with the Germans during World War II, he died while awaiting trial in liberated France toward the end of 1944 under uncertain circumstances. His company was seized and nationalized by the provisional government of France although he died before he could be tried. His factories were the only ones permanently expropriated by the French government.

In 1956, Time Magazine described Renault as "rich, powerful and famous, cantankerous, brilliant, often brutal, the little Napoleon of an automaking empire — vulgar, loud, domineering, impatient, he was a terror to associates, a friend to practically none," adding that to the French working man, Renault became known as "the ogre of Billancourt."

1915 – In Washington, D.C., the first stone of the Lincoln Memorial is put into place.

The Lincoln Memorial is an American national memorial built to honor the 16th President of the United States, Abraham Lincoln. It is located on the western end of the National Mall in Washington, D.C., across from the Washington Monument. The architect was Henry Bacon; the designer of the primary statue – Abraham Lincoln, 1920 – was Daniel Chester French; the Lincoln statue was carved by the Piccirilli Brothers; and the painter of the interior murals was Jules Guerin. Dedicated in May 1922, it is one of several memorials built to honor an American president. It has always been a major tourist attraction and since the 1930s has been a symbolic center focused on race relations.

The building is in the form of a Greek Doric temple and contains a large seated sculpture of Abraham Lincoln and inscriptions of two well-known speeches by Lincoln, The Gettysburg Address and his second inaugural address. The memorial has been the site of many famous speeches, including Martin Luther King Jr.'s "I Have a Dream" speech, delivered on August 28, 1963, during the rally at the end of the March on Washington for Jobs and Freedom.

Like other monuments on the National Mall – including the nearby Vietnam Veterans Memorial, Korean War Veterans Memorial, and National World War II Memorial – the memorial is administered by the National Park Service under its National Mall and Memorial Parks group. It has been listed on the National Register of Historic Places since October 15, 1966, and was ranked seventh on the American Institute of Architects 2007 list of America's Favorite Architecture. The memorial is open to the public 24 hours a day, and more than seven million people visit it annually.

Here are some events that happened on February 11th. It could be an event or a person that died or was born on that day


1650 Died: René Descartes, French mathematician and philosopher (b. 1596)

René Descartes (31 March 1596 – 11 February 1650) was a French philosopher, mathematician, and scientist. A native of the Kingdom of France, he spent about 20 years (1629–1649) of his life in the Dutch Republic after serving for a while in the Dutch States Army of Maurice of Nassau, Prince of Orange and the Stadtholder of the United Provinces. One of the most notable intellectual figures of the Dutch Golden Age, Descartes is also widely regarded as one of the founders of modern philosophy.

Many elements of Descartes' philosophy have precedents in late Aristotelianism, the revived Stoicism of the 16th century, or in earlier philosophers like Augustine. In his natural philosophy, he differed from the schools on two major points: first, he rejected the splitting of corporeal substance into matter and form; second, he rejected any appeal to final ends, divine or natural, in explaining natural phenomena. In his theology, he insists on the absolute freedom of God's act of creation. Refusing to accept the authority of previous philosophers, Descartes frequently set his views apart from the philosophers who preceded him. In the opening section of the Passions of the Soul, an early modern treatise on emotions, Descartes goes so far as to assert that he will write on this topic "as if no one had written on these matters before". His best known philosophical statement is "I think, therefore I am" (French: Je pense, donc je suis; Latin: cogito, ergo sum), found in Discourse on the Method (1637; written in French and Latin) and Principles of Philosophy (1644; written in Latin).

Descartes laid the foundation for 17th-century continental rationalism, later advocated by Spinoza and Leibniz, and was later opposed by the empiricist school of thought consisting of Hobbes, Locke, Berkeley, and Hume. Leibniz, Spinoza, and Descartes were all well-versed in mathematics as well as philosophy, and Descartes and Leibniz contributed greatly to science as well. Descartes' Meditations on First Philosophy (1641) continues to be a standard text at most university philosophy departments. Descartes' influence in mathematics is equally apparent; the Cartesian coordinate system was named after him. He is credited as the father of analytical geometry, the bridge between algebra and geometry—used in the discovery of infinitesimal calculus and analysis. Descartes was also one of the key figures in the Scientific Revolution.

1795 Died: Carl Michael Bellman, Swedish poet and composer (b. 1740)

Carl Michael Bellman (4 February 1740 – 11 February 1795) was a Swedish songwriter, composer, musician, poet and entertainer. He is a central figure in the Swedish song tradition and remains a powerful influence in Swedish music, as well as in Scandinavian literature, to this day. He has been compared to Shakespeare, Beethoven, Mozart, and Hogarth, but his gift, using elegantly rococo classical references in comic contrast to sordid drinking and prostitution—at once regretted and celebrated in song—is unique.

Bellman is best known for two collections of poems set to music, Fredman's songs (Fredmans sånger) and Fredman's epistles (Fredmans epistlar). Each consists of about 70 songs. The general theme is drinking, but the songs "most ingeniously" combine words and music to express feelings and moods ranging from humorous to elegiac, romantic to satirical.

Bellman's patrons included King Gustav III of Sweden, who called him a master improviser. Bellman's songs continue to be performed and recorded by musicians from Scandinavia and in other languages, including English, French, German, Italian and Russian. Several of his songs including Gubben Noak and Fjäriln vingad are known by heart by many Swedes. His legacy further includes a museum in Stockholm and a society that fosters interest in him and his work.

1847 Born: Thomas Edison, American engineer and businessman, invented the light bulb and phonograph (d. 1931)

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who has been described as America's greatest inventor. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory.

Edison was raised in the American Midwest; early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanic laboratory in Fort Myers, Florida in collaboration with businessmen Henry Ford and Harvey S. Firestone, and a laboratory in West Orange, New Jersey that featured the world's first film studio, the Black Maria.

1868 Died: Léon Foucault, French physicist and academic (b. 1819 )

Jean Bernard Léon Foucault (18 September 1819 – 11 February 1868) was a French physicist best known for his demonstration of the Foucault pendulum, a device demonstrating the effect of the Earth's rotation. He also made an early measurement of the speed of light, discovered eddy currents, and is credited with naming the gyroscope.

Foucault died of what was probably a rapidly developing case of multiple sclerosis on 11 February 1868 in Paris and was buried in the Montmartre Cemetery.

The asteroid 5668 Foucault was named for him.[10] His is one of the 72 names inscribed on the Eiffel Tower.

1901 Died: Milan I of Serbia (b. 1855)

Milan Obrenović (22 August 1854 – 11 February 1901) was the ruler of Serbia from 1868 to 1889, first as prince (1868-1882), subsequently as king (1882-1889).

Milan Obrenović was born in 1854 in Mărășești, Moldavia where his family lived in exile ever since the 1842 return of the rival House of Karađorđević to the Serbian throne when they managed to depose Milan's cousin Prince Mihailo Obrenović III.

Milan was the son of Miloš Obrenović (1829–1861) and his Moldavian wife Marija Obrenović (née Elena Maria Catargiu). Milan's paternal grandfather (Miloš's father) was Jevrem Obrenović (1790–1856), brother of Miloš Obrenović I, Prince of Serbia. Milan was therefore Prince Miloš's grandnephew. He had only one sibling — sister Tomanija.

Shortly after Milan's birth, his parents divorced. Several years later on 20 November 1861, at the age of seven, Milan's father Miloš died fighting the Turks near Bucharest as a foreign mercenary in the Romanian Army, meaning that his mother Marija got a legal custody. Marija, however, lived a lavish aristocratic lifestyle, soon becoming Romanian ruler Alexandru Ioan Cuza's mistress and bearing him two sons — Alexandru Al. Ioan Cuza (nicknamed Sașa) and Dimitrie. As a result, she showed little interest in her children from the previous marriage with Miloš. Therefore, an agreement was reached for young Milan to get legally adopted by his cousin Mihailo Obrenović. who in the meantime, following the 1858 expulsion of the Karađorđevićs, had returned to Serbia where he became the ruling prince in 1860.

On 10 June 1868, when Milan was only fourteen years of age, Prince Mihailo Obrenović III was assassinated. As the late prince did not have any male heirs, the question of who was to succeed him on the Serbian throne became a pressing one. In the post-assassination chaos and the resulting power vacuum, influential senior statesman Ilija Garašanin re-emerged in Serbian political life, despite only eight months earlier being removed by the late prince from the post of Prime Minister of Serbia and replaced with Jovan Ristić. While consolidating forces within the state to prevent the conspirators from taking over the power, Garašanin also reportedly contemplated solving the throne issue by starting a third royal dynasty. General political consensus was that the new ruler should be selected by the Visoka narodna skupština (Grand National Council). However, cabinet minister Milivoje Petrović Blaznavac was rapidly increasing his power and influence. He had managed to consolidate his control over the army and stage a coup d'état. So when Blaznavac suggested the young Milan as the successor to Prince Mihailo, Garašanin had no choice but to yield to the more powerful authority.

On 22 August 1872, Milan was declared of age, and he took government into his own hands. He soon demonstrated great intellectual capacity, coupled with a passionate headstrong character. Eugene Schuyler, who observed him about this time, found him to be a very remarkable, singularly intelligent and well-informed young man. The Principality of Serbia was still a de jure part of the Ottoman Empire though in reality it already had long functioned as a semi-independent state whose politics and economy was much more dependent on other Great Powers, particularly Austria-Hungary and Russian Empire, than on its formal ruler, the declining Ottomans. Milan carefully manoeuvred between the Austrian and Russian geopolitical interests in Serbia, with a judicious leaning towards the former.

On 3 January 1889, Milan adopted a new constitution much more liberal than the existing one of 1869. Two months later, on 6 March, thirty-four-year-old Milan suddenly abdicated the throne, handing it over to his twelve-year-old son. No satisfactory reason was assigned for this step. Milan settled in Paris as a private individual.
