Nobel laureates 1901: Wilhelm Röntgen, Jacobus Henricus van 't Hoff, Emil Adolf von Behring, Sully Prudhomme, Henry Dunant, Frédéric Passy

The Nobel Prizes (Swedish: Nobelpriset, Norwegian: Nobelprisen) are prizes awarded annually by the Royal Swedish Academy of Sciences, the Swedish Academy, the Karolinska Institutet, and the Norwegian Nobel Committee to individuals and organizations who make outstanding contributions in the fields of chemistry, physics, literature, peace, and physiology or medicine. They were established by the 1895 will of Alfred Nobel, which dictates that the awards should be administered by the Nobel Foundation. The Nobel Memorial Prize in Economic Sciences was established in 1968 by the Sveriges Riksbank, the central bank of Sweden, for contributions to the field of economics. Each recipient, or "laureate", receives a gold medal, a diploma, and a sum of money, which is decided annually by the Nobel Foundation

Here is a list of 1901 Nobel laureates  

Physics: Wilhelm Röntgen, German physicist and academic

Wilhelm Conrad Röntgen (27 March 1845 – 10 February 1923) was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the first Nobel Prize in Physics in 1901. In honour of his accomplishments, in 2004 the International Union of Pure and Applied Chemistry (IUPAC) named element 111, roentgenium, a radioactive element with multiple unstable isotopes, after him.

Today, in Remscheid-Lennep, 40 kilometers east of Düsseldorf, the town in which Röntgen was born in 1845 is the Deutsches Röntgen-Museum.
In Würzburg, where he discovered the X-rays, a non-profit organization maintains his laboratory and provides guided tours to the Röntgen Memorial Site.

World Radiology Day: The International Day of Radiology is an annual event promoting the role of medical imaging in modern healthcare. It is celebrated on 8 November each year, coincides with the anniversary of the discovery of X-rays by Wilhelm Roentgen in 1895. It was first introduced in 2012, as a joint initiative, by the European Society of Radiology (ESR), the Radiological Society of North America (RSNA), and the American College of Radiology (ACR).

Chemistry: Jacobus Henricus van 't Hoff, Dutch chemist and academic

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.

Physiology or Medicine: Emil von Behring, German physiologist and immunologist

Emil von Behring (Emil Adolf von Behring), born Emil Adolf Behring (15 March 1854 – 31 March 1917), was a German physiologist who received the 1901 Nobel Prize in Physiology or Medicine, the first one awarded in that field, for his discovery of a diphtheria antitoxin. He was widely known as a "saviour of children," as diphtheria used to be a major cause of child death. He was honored with Prussian nobility in 1901, henceforth being known by the surname "von Behring."

In 1895 he became Professor of Hygienics within the Faculty of Medicine at the University of Marburg, a position he would hold for the rest of his life. He and the pharmacologist Hans Horst Meyer had their laboratories in the same building, and Behring stimulated Meyer's interest in the mode of action of tetanus toxin.

Behring won the first Nobel Prize in Physiology or Medicine in 1901 for the development of serum therapies against diphtheria. He was elected a Foreign Honorary Member of the American Academy of Arts and Sciences in 1902.

In 1904 he founded the Behringwerke in Marburg, a company to produce antitoxins and vaccines.

At the International Tuberculosis Congress in 1905 he announced that he had discovered "a substance proceeding from the virus of tuberculosis." This substance, which he designated "T C," plays the important part in the immunizing action of his "bovivaccine", which prevents bovine tuberculosis. He tried unsuccessfully to obtain a protective and therapeutic agents for humans.

Behring died at Marburg, Hessen-Nassau, on 31 March 1917. His name survived in the Dade Behring organisation (now part of the Siemens Healthineers), in CSL Behring, a manufacturer of plasma-derived biotherapies, in Novartis Behring and in the Emil von Behring Prize of the University of Marburg, the highest endowed medicine award in Germany.

His Nobel Prize medal is now kept on display at the International Red Cross and Red Crescent Museum in Geneva.

Literature: Sully Prudhomme, French poet and critic

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.

Peace: Henry Dunant, Swiss businessman and activist, co-founded the Red Cross

Henry Dunant (born Jean-Henri Dunant; 8 May 1828 – 30 October 1910), also known as Henri Dunant, was a Swiss humanitarian, businessman and social activist. He was the visionary, promoter and co-founder of the Red Cross.

During a business trip in 1859, Dunant was witness to the aftermath of the Battle of Solferino in modern-day Italy. He recorded his memories and experiences in the book A Memory of Solferino which inspired the creation of the International Committee of the Red Cross (ICRC) in 1863. The 1864 Geneva Convention was based on Dunant's idea for an independent organisation to care for wounded soldiers.

Dunant was the founder of the Swiss branch of the Young Men's Christian Association YMCA.

In 1901 he received the first Nobel Peace Prize together with Frédéric Passy, making Dunant the first Swiss Nobel laureate.

Peace: Frédéric Passy, French economist and academic

Frédéric Passy (20 May 1822 – 12 June 1912) was a French economist and pacifist who was a founding member of several peace societies and the Inter-Parliamentary Union. He was also an author and politician, sitting in the Chamber of Deputies from 1881 until 1889. He was a joint winner of the Nobel Peace Prize in 1901 for his work in the European peace movement.

Born in Paris to a prominent Catholic and Orléanist family, Passy was surrounded by military veterans and politicians. After training in law, he worked as an accountant and served in the National Guard. He soon left this position and began travelling around France giving lectures on economics. Following years of violent conflicts across Europe, Passy joined the peace movement in the 1850s, working with several notable activists and writers to develop journals, articles, and educational curricula.

While sitting in the Chamber of Deputies, Passy developed the Inter-parliamentary Conference (later the Inter-Parliamentary Union) with British MP William Randal Cremer. Alongside this, he founded several peace societies: the Ligue Internationale et Permanente de la Paix, the Société Française des Amis de la Paix, and the Société Française pour l'Arbitrage entre Nations. Passy's work in the peace movement continued into his later years, and in 1901, he was awarded the Nobel Peace Prize alongside Red Cross founder, Henry Dunant.

Passy died in 1912 after a long period of illness and incapacitation. Despite his economic works gaining little traction, his efforts in the peace movement resulted in him being recognised as the "dean of European peace activists".:34 His son, Paul Passy, published a memoir of his life in 1927, and his works are still being republished and translated into English in the 21st Century.

Here are some events that happened on June 27th. It could be an event or a person that died or was born on that day

1358 – The Republic of Ragusa is founded.

The Republic of Ragusa (Latin: Respublica Ragusina; Italian: Repubblica di Ragusa; Croatian: Dubrovačka Republika, lit. 'Dubrovnik Republic'; Venetian: Repùblega de Raguxa) was an aristocratic maritime republic centered on the city of Dubrovnik (Ragusa in Italian, German and Latin; Raguxa in Venetian) in Dalmatia (today in southernmost Croatia) that carried that name from 1358 until 1808. It reached its commercial peak in the 15th and the 16th centuries, before being conquered by Napoleon's French Empire and formally annexed by the Napoleonic Kingdom of Italy in 1808. It had a population of about 30,000 people, of whom 5,000 lived within the city walls. Its motto was "Non bene pro toto libertas venditur auro", which means "Liberty is not sold for all the gold in the world"

1574 Died: Giorgio Vasari, Italian historian, painter, and architect (b. 1511)

Giorgio Vasari (30 July 1511 – 27 June 1574) was an Italian painter, architect, engineer, writer, and historian, best known for his Lives of the Most Excellent Painters, Sculptors, and Architects, considered the ideological foundation of art-historical writing, and basis for biographies of several Renaissance artists including Leonardo da Vinci. Vasari designed the Tomb of Michelangelo in the Basilica of Santa Croce, Florence that was completed in 1578. Based on Vasari's text about Giotto's new manner of painting, Jules Michelet suggested for the first time the term Renaissance in his Histoire de France (1835), a term adopted by historiography and still in use today.

Aside from his career as a painter, Vasari was also successful as an architect. His loggia of the Palazzo degli Uffizi by the Arno opens up the vista at the far end of its long narrow courtyard. It is a unique piece of urban planning that functions as a public piazza, and which, if considered as a short street, is unique as a Renaissance street with a unified architectural treatment. The view of the Loggia from the Arno reveals that, with the Vasari Corridor, it is one of very few structures that line the river which are open to the river itself and appear to embrace the riverside environment.

In Florence, Vasari also built the long passage, now called Vasari Corridor, which connects the Uffizi with the Palazzo Pitti on the other side of the river. The enclosed corridor passes alongside the River Arno on an arcade, crosses the Ponte Vecchio and winds around the exterior of several buildings. It was once the home of the Mercado de Vecchio.

He also renovated the medieval churches of Santa Maria Novella and Santa Croce. At both he removed the original rood screen and loft, and remodeled the retro-choirs in the Mannerist taste of his time. In Santa Croce, he was responsible for the painting of The Adoration of the Magi which was commissioned by Pope Pius V in 1566 and completed in February 1567. It was recently restored, before being put on exhibition in 2011 in Rome and in Naples. Eventually it is planned to return it to the church of Santa Croce in Bosco Marengo (Province of Alessandria, Piedmont).

In 1562 Vasari built the octagonal dome on the Basilica of Our Lady of Humility in Pistoia, an important example of high Renaissance architecture.

In Rome, Vasari worked with Giacomo Barozzi da Vignola and Bartolomeo Ammannati at Pope Julius III's Villa Giulia.

1831 Died: Sophie Germain, French mathematician and physicist (b. 1776)

Marie-Sophie Germain (1 April 1776 – 27 June 1831) was a French mathematician, physicist, and philosopher. Despite initial opposition from her parents and difficulties presented by society, she gained education from books in her father's library, including ones by Leonhard Euler, and from correspondence with famous mathematicians such as Lagrange, Legendre, and Gauss (under the pseudonym of «Monsieur LeBlanc»). One of the pioneers of elasticity theory, she won the grand prize from the Paris Academy of Sciences for her essay on the subject. Her work on Fermat's Last Theorem provided a foundation for mathematicians exploring the subject for hundreds of years after. Because of prejudice against her sex, she was unable to make a career out of mathematics, but she worked independently throughout her life. Before her death, Gauss had recommended that she be awarded an honorary degree, but that never occurred. On 27 June 1831, she died from breast cancer. At the centenary of her life, a street and a girls’ school were named after her. The Academy of Sciences established the Sophie Germain Prize in her honor

Here are some events that happened on June 19th. It could be an event or a person that died or was born on that day

1623 Born: Blaise Pascal, French mathematician and physicist (d. 1662)

Blaise Pascal (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, writer and Catholic theologian. He was a child prodigy who was educated by his father, a tax collector in Rouen. Pascal's earliest work was in the natural and applied sciences, where he made important contributions to the study of fluids, and clarified the concepts of pressure and vacuum by generalising the work of Evangelista Torricelli. Pascal also wrote in defence of the scientific method.

In 1642, while still a teenager, he started some pioneering work on calculating machines. After three years of effort and 50 prototypes, he built 20 finished machines (called Pascal's calculators and later Pascalines) over the following 10 years, establishing him as one of the first two inventors of the mechanical calculator.

Pascal was an important mathematician, helping create two major new areas of research: he wrote a significant treatise on the subject of projective geometry at the age of 16, and later corresponded with Pierre de Fermat on probability theory, strongly influencing the development of modern economics and social science. Following Galileo Galilei and Torricelli, in 1647, he rebutted Aristotle's followers who insisted that nature abhors a vacuum. Pascal's results caused many disputes before being accepted.

In 1646, he and his sister Jacqueline identified with the religious movement within Catholicism known by its detractors as Jansenism. Following a religious experience in late 1654, he began writing influential works on philosophy and theology. His two most famous works date from this period: the Lettres provinciales and the Pensées, the former set in the conflict between Jansenists and Jesuits. In that year, he also wrote an important treatise on the arithmetical triangle. Between 1658 and 1659, he wrote on the cycloid and its use in calculating the volume of solids.

Throughout his life, Pascal was in frail health, especially after the age of 18; he died just two months after his 39th birthday.

1867 – Maximilian I of the Second Mexican Empire is executed by a firing squad in Querétaro, Querétaro.

Maximilian I (Spanish: Fernando Maximiliano José María de Habsburgo-Lorena; 6 July 1832 – 19 June 1867) was the only monarch of the Second Mexican Empire. He was a younger brother of the Austrian emperor Franz Joseph I. After a distinguished career in the Austrian Navy as its commander, he accepted an offer by Napoleon III of France to rule Mexico, conditional on a national plebiscite in his favour.

1778 Died: Voltaire, French philosopher and author (b. 1694)

François-Marie Arouet (21 November 1694 – 30 May 1778), known by his nom de plume Voltaire , was a French Enlightenment writer, historian, and philosopher famous for his wit, his criticism of Christianity—especially the Roman Catholic Church—as well as his advocacy of freedom of speech, freedom of religion, and separation of church and state.

Voltaire was a versatile and prolific writer, producing works in almost every literary form, including plays, poems, novels, essays, histories, and scientific expositions. He wrote more than 20,000 letters and 2,000 books and pamphlets. He was one of the first authors to become renowned and commercially successful internationally. He was an outspoken advocate of civil liberties, and he was at constant risk from the strict censorship laws of the Catholic French monarchy. His polemics witheringly satirized intolerance, religious dogma, and the French institutions of his day.

François-Marie Arouet was born in Paris, the youngest of the five children of François Arouet (1649–1722), a lawyer who was a minor treasury official, and his wife, Marie Marguerite Daumard (c. 1660–1701), whose family was on the lowest rank of the French nobility. Some speculation surrounds Voltaire's date of birth, because he claimed he was born on 20 February 1694 as the illegitimate son of a nobleman, Guérin de Rochebrune or Roquebrune. Two of his older brothers—Armand-François and Robert—died in infancy, and his surviving brother Armand and sister Marguerite-Catherine were nine and seven years older, respectively. Nicknamed "Zozo" by his family, Voltaire was baptized on 22 November 1694, with François de Castagnère, abbé de Châteauneuf, and Marie Daumard, the wife of his mother's cousin, standing as godparents. He was educated by the Jesuits at the Collège Louis-le-Grand (1704–1711), where he was taught Latin, theology, and rhetoric; later in life he became fluent in Italian, Spanish, and English.

By the time he left school, Voltaire had decided he wanted to be a writer, against the wishes of his father, who wanted him to become a lawyer. Voltaire, pretending to work in Paris as an assistant to a notary, spent much of his time writing poetry. When his father found out, he sent Voltaire to study law, this time in Caen, Normandy. But the young man continued to write, producing essays and historical studies. Voltaire's wit made him popular among some of the aristocratic families with whom he mixed. In 1713, his father obtained a job for him as a secretary to the new French ambassador in the Netherlands, the marquis de Châteauneuf, the brother of Voltaire's godfather. At The Hague, Voltaire fell in love with a French Protestant refugee named Catherine Olympe Dunoyer (known as 'Pimpette'). Their affair, considered scandalous, was discovered by de Châteauneuf and Voltaire was forced to return to France by the end of the year.

Voltaire was imprisoned in the Bastille from 16 May 1717 to 15 April 1718 in a windowless cell with ten-foot-thick walls.

Most of Voltaire's early life revolved around Paris. From early on, Voltaire had trouble with the authorities for critiques of the government. As a result, he was twice sentenced to prison and once to temporary exile to England. One satirical verse, in which Voltaire accused the Régent of incest with his daughter, resulted in an eleven-month imprisonment in the Bastille. The Comédie-Française had agreed in January 1717 to stage his debut play, Œdipe, and it opened in mid-November 1718, seven months after his release. Its immediate critical and financial success established his reputation. Both the Régent and King George I of Great Britain presented Voltaire with medals as a mark of their appreciation.

He mainly argued for religious tolerance and freedom of thought. He campaigned to eradicate priestly and aristo-monarchical authority, and supported a constitutional monarchy that protects people's rights.

Voltaire's best-known histories are History of Charles XII (1731), The Age of Louis XIV (1751), and his Essay on the Customs and the Spirit of the Nations (1756). He broke from the tradition of narrating diplomatic and military events, and emphasized customs, social history and achievements in the arts and sciences. The Essay on Customs traced the progress of world civilization in a universal context, rejecting both nationalism and the traditional Christian frame of reference. Influenced by Bossuet's Discourse on Universal History (1682), he was the first scholar to attempt seriously a history of the world, eliminating theological frameworks, and emphasizing economics, culture and political history. He treated Europe as a whole rather than a collection of nations. He was the first to emphasize the debt of medieval culture to Middle Eastern civilization, but otherwise was weak on the Middle Ages. Although he repeatedly warned against political bias on the part of the historian, he did not miss many opportunities to expose the intolerance and frauds of the church over the ages. Voltaire advised scholars that anything contradicting the normal course of nature was not to be believed. Although he found evil in the historical record, he fervently believed reason and expanding literacy would lead to progress.

Voltaire explains his view of historiography in his article on "History" in Diderot's Encyclopédie: "One demands of modern historians more details, better ascertained facts, precise dates, more attention to customs, laws, mores, commerce, finance, agriculture, population." Voltaire's histories imposed the values of the Enlightenment on the past, but at the same time he helped free historiography from antiquarianism, Eurocentrism, religious intolerance and a concentration on great men, diplomacy, and warfare. Yale professor Peter Gay says Voltaire wrote "very good history", citing his "scrupulous concern for truths", "careful sifting of evidence", "intelligent selection of what is important", "keen sense of drama", and "grasp of the fact that a whole civilization is a unit of study"

From an early age, Voltaire displayed a talent for writing verse, and his first published work was poetry. He wrote two book-long epic poems, including the first ever written in French, the Henriade, and later, The Maid of Orleans, besides many other smaller pieces.

The Henriade was written in imitation of Virgil, using the alexandrine couplet reformed and rendered monotonous for modern readers but it was a huge success in the 18th and early 19th century, with sixty-five editions and translations into several languages. The epic poem transformed French King Henry IV into a national hero for his attempts at instituting tolerance with his Edict of Nantes. La Pucelle, on the other hand, is a burlesque on the legend of Joan of Arc.

1806 – Future U.S. President Andrew Jackson kills Charles Dickinson in a duel.

Andrew Jackson (March 15, 1767 – June 8, 1845) was an American soldier and statesman who served as the seventh president of the United States from 1829 to 1837. Before being elected to the presidency, Jackson gained fame as a general in the United States Army and served in both houses of the U.S. Congress. As president, Jackson sought to advance the rights of the "common man" against a "corrupt aristocracy" and to preserve the Union.

Born in the colonial Carolinas to a Scotch-Irish family in the decade before the American Revolutionary War, Jackson became a frontier lawyer and married Rachel Donelson Robards. He served briefly in the United States House of Representatives and the United States Senate, representing Tennessee. After resigning, he served as a justice on the Tennessee Supreme Court from 1798 until 1804. Jackson purchased a property later known as The Hermitage, and became a wealthy, slaveowning planter. In 1801, he was appointed colonel of the Tennessee militia and was elected its commander the following year. He led troops during the Creek War of 1813–1814, winning the Battle of Horseshoe Bend. The subsequent Treaty of Fort Jackson required the Creek surrender of vast lands in present-day Alabama and Georgia. In the concurrent war against the British, Jackson's victory in 1815 at the Battle of New Orleans made him a national hero. Jackson then led U.S. forces in the First Seminole War, which led to the annexation of Florida from Spain. Jackson briefly served as Florida's first territorial governor before returning to the Senate. He ran for president in 1824, winning a plurality of the popular and electoral vote. As no candidate won an electoral majority, the House of Representatives elected John Quincy Adams in a contingent election. In reaction to the alleged "corrupt bargain" between Adams and Henry Clay and the ambitious agenda of President Adams, Jackson's supporters founded the Democratic Party.

Jackson ran again in 1828, defeating Adams in a landslide. Jackson faced the threat of secession by South Carolina over what opponents called the "Tariff of Abominations." The crisis was defused when the tariff was amended, and Jackson threatened the use of military force if South Carolina attempted to secede. In Congress, Henry Clay led the effort to reauthorize the Second Bank of the United States. Jackson, regarding the Bank as a corrupt institution, vetoed the renewal of its charter. After a lengthy struggle, Jackson and his allies thoroughly dismantled the Bank. In 1835, Jackson became the only president to completely pay off the national debt, fulfilling a longtime goal. His presidency marked the beginning of the ascendancy of the party "spoils system" in American politics. In 1830, Jackson signed the Indian Removal Act, which forcibly relocated most members of the Native American tribes in the South to Indian Territory. The relocation process dispossessed the Indians and resulted in widespread death and disease. Jackson opposed the abolitionist movement, which grew stronger in his second term. In foreign affairs, Jackson's administration concluded a "most favored nation" treaty with Great Britain, settled claims of damages against France from the Napoleonic Wars, and recognized the Republic of Texas. In January 1835, he survived the first assassination attempt on a sitting president.

In his retirement, Jackson remained active in Democratic Party politics, supporting the presidencies of Martin Van Buren and James K. Polk. Though fearful of its effects on the slavery debate, Jackson advocated the annexation of Texas, which was accomplished shortly before his death. Jackson has been widely revered in the United States as an advocate for democracy and the common man. Many of his actions proved divisive, garnering both fervent support and strong opposition from many in the country. His reputation has suffered since the 1970s, largely due to his role in Native American removal. Surveys of historians and scholars have ranked Jackson favorably among U.S. presidents.

1912 Died: Wilbur Wright, American pilot and businessman, co-founded the Wright Company (b. 1867)

The Wright brothers—Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912)—were two American aviation pioneers generally credited with inventing, building, and flying the world's first successful motor-operated airplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, 4 mi (6 km) south of Kitty Hawk, North Carolina. In 1904–05, the brothers developed their flying machine to make longer-running and more aerodynamic flights with the Wright Flyer II, followed by the first truly practical fixed-wing aircraft, the Wright Flyer III. The Wright brothers were also the first to invent aircraft controls that made fixed-wing powered flight possible.

The brothers' breakthrough was their creation of a three-axis control system, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium. This method remains standard on fixed-wing aircraft of all kinds.  From the beginning of their aeronautical work, the Wright brothers focused on developing a reliable method of pilot control as the key to solving "the flying problem". This approach differed significantly from other experimenters of the time who put more emphasis on developing powerful engines. Using a small home-built wind tunnel, the Wrights also collected more accurate data than any before, enabling them to design more efficient wings and propellers.  Their first U.S. patent did not claim invention of a flying machine, but a system of aerodynamic control that manipulated a flying machine's surfaces. 

The brothers gained the mechanical skills essential to their success by working for years in their Dayton, Ohio-based shop with printing presses, bicycles, motors, and other machinery. Their work with bicycles, in particular, influenced their belief that an unstable vehicle such as a flying machine could be controlled and balanced with practice. From 1900 until their first powered flights in late 1903, they conducted extensive glider tests that also developed their skills as pilots. Their shop employee Charlie Taylor became an important part of the team, building their first airplane engine in close collaboration with the brothers.

The Wright brothers' status as inventors of the airplane has been subject to counter-claims by various parties. Much controversy persists over the many competing claims of early aviators. Edward Roach, historian for the Dayton Aviation Heritage National Historical Park, argues that they were excellent self-taught engineers who could run a small company, but they did not have the business skills or temperament to dominate the growing aviation industry.

Here are some events that happened on May 21st. It could be an event or a person that died or was born on that day

1471 Born: Albrecht Dürer, German painter, engraver, and mathematician (d. 1528)

Albrecht Dürer (21 May 1471 – 6 April 1528), sometimes spelt in English as Durer or Duerer, without umlaut, was a German painter, printmaker, and theorist of the German Renaissance. Born in Nuremberg, Dürer established his reputation and influence across Europe when he was in his twenties due to his high-quality woodcut prints. He was in communication with the major Italian artists of his time, including Raphael, Giovanni Bellini and Leonardo da Vinci, and from 1512 he was patronized by Emperor Maximilian I. Dürer is commemorated by both the Lutheran and Episcopal Churches.

Dürer's vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts, such as the Apocalypse series (1498), are more Gothic than the rest of his work. His well-known engravings include the Knight, Death and the Devil (1513), Saint Jerome in his Study (1514) and Melencolia I (1514), which has been the subject of extensive analysis and interpretation. His watercolours also mark him as one of the first European landscape artists, while his ambitious woodcuts revolutionized the potential of that medium.

Dürer's introduction of classical motifs into Northern art, through his knowledge of Italian artists and German humanists, has secured his reputation as one of the most important figures of the Northern Renaissance. This is reinforced by his theoretical treatises, which involve principles of mathematics, perspective, and ideal proportions.

Albrecht Dürer has been credited with inventing the basic principle of ray tracing, a technique used in modern computer graphics.

1647 Died: Pieter Corneliszoon Hooft, Dutch poet and playwright (b. 1581)

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.

1686 Died: Otto von Guericke, German physicist and inventor of the Magdeburg Hemispheres (b. 1602)

Otto von Guericke (November 20, 1602 – May 11, 1686 [Julian calendar]; November 30, 1602 – May 21, 1686 [Gregorian calendar]) was a German scientist, inventor, and politician. His major scientific achievements were the establishment of the physics of vacuums, the discovery of an experimental method for clearly demonstrating electrostatic repulsion, and his advocacy for the reality of "action at a distance" and of "absolute space".

He was also a very spiritual man in the Dionysiac tradition, as were many scientists of the Enlightenment, and connected the vacuum of space to an infinite divinity. Von Guericke described this duality "as something that ‘contains all things’ and is ‘more precious than gold...more joyous that the perception of bountiful light’ and ‘comparable to the heavens’."

1703 – Daniel Defoe is imprisoned on charges of seditious libel

Daniel Defoe (born Daniel Foe; c. 1660 – 24 April 1731) was an English trader, writer, journalist, pamphleteer and spy. He is most famous for his novel Robinson Crusoe, published in 1719, which is claimed to be second only to the Bible in its number of translations. He has been seen as one of the earliest proponents of the English novel, and helped to popularize the form in Britain with others such as Aphra Behn and Samuel Richardson. Defoe wrote many political tracts and was often in trouble with the authorities, and spent a period in prison. Intellectuals and political leaders paid attention to his fresh ideas and sometimes consulted with him.

Defoe was a prolific and versatile writer, producing more than three hundred works—books, pamphlets, and journals—on diverse topics, including politics, crime, religion, marriage, psychology, and the supernatural. He was also a pioneer of business journalism and economic journalism.

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

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.

1844 Born: Henri Rousseau, French painter (d. 1910)

Henri Julien Félix Rousseau (21 May 1844 – 2 September 1910) was a French post-impressionist painter in the Naïve or Primitive manner. He was also known as Le Douanier (the customs officer), a humorous description of his occupation as a toll and tax collector. He started painting seriously in his early forties; by age 49, he retired from his job to work on his art full-time.

Ridiculed during his lifetime by critics, he came to be recognized as a self-taught genius whose works are of high artistic quality.[5][6] Rousseau's work exerted an extensive influence on several generations of avant-garde artists

At his funeral, seven friends stood at his grave: the painters Paul Signac and Manuel Ortiz de Zárate, the artist couple Robert Delaunay and Sonia Terk, the sculptor Brâncuși, Rousseau's landlord Armand Queval, and Guillaume Apollinaire who wrote the epitaph Brâncuși put on the tombstone:

We salute you Gentle Rousseau you can hear us.
Delaunay, his wife, Monsieur Queval and myself.
Let our luggage pass duty free through the gates of heaven.
We will bring you brushes paints and canvas.
That you may spend your sacred leisure in the
light and Truth of Painting.
As you once did my portrait facing the stars, lion and the gypsy.

May 19th in stamps Mustafa Kemal Atatürk, Ho Chi Minh, Jacques Cartier

Here are some events that happened on May 19th. It could be an event or a person that died or was born on that day

1535 – French explorer Jacques Cartier sets sail on his second voyage to North America with three ships, 110 men, and Chief Donnacona's two sons (whom Cartier had kidnapped during his first voyage).

Jacques Cartier (December 31, 1491 – September 1, 1557) was a Breton explorer who claimed what is now Canada for France. Jacques Cartier was the first European to describe and map the Gulf of Saint Lawrence and the shores of the Saint Lawrence River, which he named "The Country of Canadas", after the Iroquois names for the two big settlements he saw at Stadacona (Quebec City) and at Hochelaga (Montreal Island).

1881 Born: Mustafa Kemal Atatürk (official birthday), Turkish field marshal and statesman, 1st President of Turkey (d. 1938)

Kemal Atatürk (or alternatively written as Kamâl Atatürk, Mustafa Kemal Pasha until 1934, commonly referred to as Mustafa Kemal Atatürk; c. 1881 – 10 November 1938) was a Turkish field marshal, revolutionary statesman, author, and the founding father of the Republic of Turkey, serving as its first president from 1923 until his death in 1938. He undertook sweeping progressive reforms, which modernized Turkey into a secular, industrial nation. Ideologically a secularist and nationalist, his policies and theories became known as Kemalism. Due to his military and political accomplishments, Atatürk is regarded as one of the most important political leaders of the 20th century.

Atatürk came to prominence for his role in securing the Ottoman Turkish victory at the Battle of Gallipoli (1915) during World War I. Following the defeat and dissolution of the Ottoman Empire, he led the Turkish National Movement, which resisted mainland Turkey's partition among the victorious Allied powers. Establishing a provisional government in the present-day Turkish capital Ankara (known in English at the time as Angora), he defeated the forces sent by the Allies, thus emerging victorious from what was later referred to as the Turkish War of Independence. He subsequently proceeded to abolish the decrepit Ottoman Empire and proclaimed the foundation of the Turkish Republic in its place.

As the president of the newly formed Turkish Republic, Atatürk initiated a rigorous program of political, economic, and cultural reforms with the ultimate aim of building a modern, progressive and secular nation-state. He made primary education free and compulsory, opening thousands of new schools all over the country. He also introduced the Latin-based Turkish alphabet, replacing the old Ottoman Turkish alphabet. Turkish women received equal civil and political rights during Atatürk's presidency. In particular, women were given voting rights in local elections by Act no. 1580 on 3 April 1930 and a few years later, in 1934, full universal suffrage.

His government carried out a policy of Turkification, trying to create a homogeneous and unified nation. Under Atatürk, non-Turkish minorities were pressured to speak Turkish in public; non-Turkish toponyms and last names of minorities had to be changed to Turkish renditions. The Turkish Parliament granted him the surname Atatürk in 1934, which means "Father of the Turks", in recognition of the role he played in building the modern Turkish Republic. He died on 10 November 1938 at Dolmabahçe Palace in Istanbul, at the age of 57; he was succeeded as President by his long-time Prime Minister İsmet İnönü and was honored with a state funeral. His iconic mausoleum in Ankara, built and opened in 1953, is surrounded by a park called the Peace Park in honor of his famous expression "Peace at Home, Peace in the World".

In 1981, the centennial of Atatürk's birth, his memory was honored by the United Nations and UNESCO, which declared it The Atatürk Year in the World and adopted the Resolution on the Atatürk Centennial, describing him as "the leader of the first struggle given against colonialism and imperialism" and a "remarkable promoter of the sense of understanding between peoples and durable peace between the nations of the world and that he worked all his life for the development of harmony and cooperation between peoples without distinction". Atatürk is commemorated by many memorials and places named in his honor in Turkey and throughout the world.

1890 Born: Ho Chi Minh, Vietnamese politician, 1st President of Vietnam (d. 1969)

Hồ Chí Minh (19 May 1890 – 2 September 1969), born Nguyễn Sinh Cung, also known as Nguyễn Tất Thành, Nguyễn Ái Quốc, Bác Hồ, or simply Bác ('Uncle'), was a Vietnamese revolutionary and politician. He served as Prime Minister of North Vietnam from 1945 to 1955 and President from 1945 until his death in 1969. Ideologically a Marxist–Leninist, he served as Chairman and First Secretary of the Workers' Party of Vietnam.

Hồ Chí Minh led the Việt Minh independence movement from 1941 onward, establishing the Communist-ruled Democratic Republic of Vietnam in 1945 and defeating the French Union in 1954 at the Battle of Điện Biên Phủ, ending the First Indochina War. He was a key figure in the People's Army of Vietnam and the Việt Cộng during the Vietnam War, which lasted from 1955 to 1975. The Democratic Republic of Vietnam was victorious against the Republic of Vietnam and its allies, and was officially reunified with the Republic of South Vietnam in 1976. Saigon, the former capital of South Vietnam, was renamed Ho Chi Minh City in his honor. Ho officially stepped down from power in 1965 due to health problems, and died in 1969.

The details of Hồ Chí Minh's life before he came to power in Vietnam are uncertain. He is known to have used between 50 and 200 pseudonyms. Information on his birth and early life is ambiguous and subject to academic debate. At least four existing official biographies vary on names, dates, places and other hard facts while unofficial biographies vary even more widely.

Aside from being a politician, Ho was also a writer, a poet and a journalist. He wrote several books, articles and poems in French, Chinese and Vietnamese.
