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.

Here are some events that happened on May 20th. It could be an event or a person that died or was born on that day

1822 Born: Frédéric Passy, French economist and academic, Nobel Prize laureate (d. 1912)

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.

1901 Born: Max Euwe, Dutch chess player, mathematician, and author (d. 1981)

Machgielis "Max" Euwe (May 20, 1901 – November 26, 1981) was a Dutch chess player, mathematician, author, and chess administrator. He was the fifth player to become World Chess Champion, a title he held from 1935 until 1937. Euwe served as President of FIDE, the World Chess Federation, from 1970 to 1978.

In 1933, Max Euwe challenged Alekhine to a championship match. Alekhine accepted the challenge for October 1935. Earlier that year, Dutch radio sports journalist Han Hollander asked Capablanca for his views on the forthcoming match. In the rare archival film footage where Capablanca and Euwe both speak, Capablanca replies: "Dr. Alekhine's game is 20% bluff. Dr. Euwe's game is clear and straightforward. Dr. Euwe's game—not so strong as Alekhine's in some respects—is more evenly balanced." Then Euwe gives his assessment in Dutch, explaining that his feelings alternated from optimism to pessimism, but in the previous ten years, their score had been evenly matched at 7–7.

On December 15, 1935, after 30 games played in 13 different cities around the Netherlands over a period of 80 days, Euwe defeated Alekhine by 15½–14½, becoming the fifth World Chess Champion. Alekhine quickly went three games ahead, but from game 13 onwards Euwe won twice as many games as Alekhine. His title gave a huge boost to chess in the Netherlands. This was also the first world championship match in which the players had seconds to help them with analysis during adjournments.

Euwe's win was regarded as a major upset – he reportedly had believed that beating Alekhine was unlikely – and is sometimes attributed to Alekhine's alcoholism. But Salo Flohr, who was helping Euwe during the match, thought over-confidence was more of a problem than alcohol for Alekhine in this match, and Alekhine himself said he would win easily. Former World Champions Vasily Smyslov, Boris Spassky, Anatoly Karpov, and Garry Kasparov analysed the match and concluded that Euwe deserved to win and that the standard of play was worthy of a world championship. Former World Champion Vladimir Kramnik has said that Euwe won the 1935 match on merit and that the result was not affected by Alekhine's drinking before or during the match.

Euwe's performance in the great tournament of Nottingham 1936 (equal third, half a point behind Botvinnik and Capablanca, half a point ahead of Alekhine) indicated he was a worthy champion, even if he was not as dominant as the earlier champions. Reuben Fine wrote, "In the two years before the return match, Euwe's strength increased. Although he never enjoyed the supremacy over his rivals that his predecessors had, he had no superiors in this period."

Euwe lost the title to Alekhine in a rematch in 1937, also played in the Netherlands, by the lopsided margin of 15½–9½. Alekhine had given up alcohol and tobacco to prepare for the rematch, although he would start drinking again later. Alekhine got back to the sort of form he had shown from 1927–34, when he dominated chess. The match was a real contest initially, but Euwe's play collapsed near the end, and he lost four of the last five games. Fine, who was Euwe's second in this match, attributed the collapse to nervous tension, possibly aggravated by Euwe's attempts to maintain a calm appearance.

The two world title matches against Alekhine represent the heart of Euwe's career. Altogether, the two played 86 competitive games, and Alekhine had a +28−20=38 lead, according to chessgames.com. Many of Alekhine's wins came early in their series; he was nine years older, and had more experience during that time. The rematch was also one-sided in Alekhine's favour.

1908 Born: James Stewart, American actor (d. 1997)

James Maitland "Jimmy" Stewart (May 20, 1908 – July 2, 1997) was an American actor. Known for his distinctive drawl and everyman screen persona, Stewart's film career spanned 80 films from 1935 to 1991. With the strong morality he portrayed both on and off the screen, he epitomized the "American ideal" in the twentieth century. In 1999, the American Film Institute (AFI) ranked him third on its list of the greatest American male actors.

Born and raised in Indiana, Pennsylvania, Stewart started acting while studying at Princeton University. After graduating in 1932, he began a career as a stage actor, appearing on Broadway and in summer stock productions. In 1935, he landed his first of several supporting roles in movies and in 1938 he had his big breakthrough in Frank Capra's ensemble comedy You Can't Take It with You. The following year, Stewart garnered his first of five Academy Award nominations for his portrayal of an idealized and virtuous man who becomes a senator in Capra's Mr. Smith Goes to Washington (1939). He won his only Academy Award for Best Actor for his work in the comedy The Philadelphia Story (1940), which also starred Katharine Hepburn and Cary Grant.

A licensed amateur pilot, Stewart enlisted as a private in the Army Air Corps soon after the United States entered the Second World War in 1941. After fighting in the European theater, he attained the rank of colonel and had received several awards for his service. He remained in the U.S. Air Force Reserve and was promoted to brigadier general in 1959. He retired in 1968 and was awarded the United States Air Force Distinguished Service Medal. President Ronald Reagan would later promote Stewart to the rank of major general in the Air Force retired list, in 1985.

Stewart's first postwar role was as George Bailey in Capra's It's a Wonderful Life (1946). Although it earned him an Oscar nomination, the film was not a big success at first. It has increased in popularity since its release, and is considered a Christmas classic and one of Stewart's most famous performances. In the 1950s, Stewart played darker, more morally ambiguous characters in movies directed by Anthony Mann, including Winchester '73 (1950), The Glenn Miller Story (1954) and The Naked Spur (1953), and by Alfred Hitchcock in Rope (1948), Rear Window (1954), The Man Who Knew Too Much (1956), and Vertigo (1958). Vertigo was ignored by critics upon release, but is now recognized as an American cinematic masterpiece. His other films in the 1950s included the Broadway adaptation Harvey (1950) and the courtroom drama Anatomy of a Murder (1959), both of which landed him Academy Award nominations. He was one of the most popular film stars of the decade, with most of his films becoming box office successes.

Stewart's later Westerns included The Man Who Shot Liberty Valance (1962) and Cheyenne Autumn (1964), both directed by John Ford. He appeared in many popular family comedies during the 1960s. After a brief venture into television acting, Stewart semi-retired by the 1980s. He received many honorary awards, including an Academy Honorary Award and the Presidential Medal of Freedom, both in 1985.

Stewart remained unmarried until his 40s and was dubbed "The Great American Bachelor" by the press. In 1949, he married former model Gloria Hatrick McLean. They had twin daughters, and he adopted her two sons from her previous marriage. The marriage lasted until McLean's death in 1994; Stewart died of a pulmonary embolism three years later.

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

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.

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.

Here are some events that happened on May 18th. It could be an event or a person that died or was born on that day

1711 Born: Roger Joseph Boscovich, Ragusan physicist, astronomer, and mathematician (d. 1787)

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.

1804 – Napoleon Bonaparte is proclaimed Emperor of the French by the French Senate.

Napoleon Bonaparte (15 August 1769 – 5 May 1821), born Napoleone di Buonaparte, was a French statesman and military leader who became famous as an artillery commander during the French Revolution. He led many successful campaigns during the French Revolutionary Wars and was Emperor of the French as Napoleon I from 1804 until 1814 and again briefly in 1815 during the Hundred Days. Napoleon dominated European and global affairs for more than a decade while leading France against a series of coalitions during the Napoleonic Wars. He won many of these wars and a vast majority of his battles, building a large empire that ruled over much of continental Europe before its final collapse in 1815. He is considered one of the greatest commanders in history, and his wars and campaigns are studied at military schools worldwide. Napoleon's political and cultural legacy has made him one of the most celebrated and controversial leaders in human history.  

Napoleon's influence on the modern world brought liberal reforms to the numerous territories that he conquered and controlled, such as the Low Countries, Switzerland, and large parts of modern Italy and Germany. He implemented fundamental liberal policies in France and throughout Western Europe. His Napoleonic Code has influenced the legal systems of more than 70 nations around the world. British historian Andrew Roberts states: "The ideas that underpin our modern world—meritocracy, equality before the law, property rights, religious toleration, modern secular education, sound finances, and so on—were championed, consolidated, codified and geographically extended by Napoleon. To them he added a rational and efficient local administration, an end to rural banditry, the encouragement of science and the arts, the abolition of feudalism and the greatest codification of laws since the fall of the Roman Empire".

1860 – Abraham Lincoln wins the Republican Party presidential nomination over William H. Seward, who later becomes the United States Secretary of State.

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.

1868 Born: Nicholas II of Russia (d. 1918)

Nicholas II or Nikolai II Alexandrovich Romanov (18 May  1868 – 17 July 1918), known in the Russian Orthodox Church as Saint Nicholas the Passion-Bearer, was the last Tsar of Russia, ruling from 1 November 1894 until his forced abdication on 15 March 1917. His reign saw the fall of the Russian Empire from one of the foremost great powers of the world to economic and military collapse. His memory was reviled by Soviet historians as a weak and incompetent leader whose decisions led to military defeats and the deaths of millions of his subjects. By contrast Anglo-Russian historian Nikolai Tolstoy, leader of the International Monarchist League, says, "There were many bad things about the Tsar's regime, but he inherited an autocracy and his acts are now being seen in perspective and in comparison to the terrible crimes committed by the Soviets."

As Emperor, Nicholas gave limited support to the economic and political reforms promoted by top aides Sergei Witte and Pyotr Stolypin, but they faced too much aristocratic opposition to be fully effective. He supported modernization based on foreign loans and close ties with France, but resisted giving the new parliament (the Duma) major roles. He was criticised for the Khodynka Tragedy, antisemitic pogroms, Bloody Sunday, the violent suppression of the 1905 Russian Revolution, the repression of political opponents, and his perceived responsibility for defeat in the Russo-Japanese War (1904–1905), which saw the annihilation of the Russian Baltic Fleet at the Battle of Tsushima, the loss of Russian influence over Manchuria and Korea, and the Japanese annexation of the north of South Sakhalin Island.

Nicholas signed the Anglo-Russian Entente of 1907, which was designed to counter Germany's attempts to gain influence in the Middle East; it ended the Great Game of confrontation between Russia and the British Empire. He supported Serbia and approved the mobilization of the Russian Army on 30 July 1914. In response, Germany declared war on Russia on 1 August 1914 and its ally France on 3 August 1914, starting the First World War. The aristocracy was alarmed at the powerful influence of the despised peasant priest Grigori Rasputin over the tsar. The severe military losses led to a collapse of morale at the front and at home, leading to the fall of the House of Romanov in the February Revolution of 1917. Nicholas abdicated on behalf of himself and his son. With his family he was imprisoned by the Bolsheviks and executed in July 1918.

1922 Died: Charles Louis Alphonse Laveran, French physician and parasitologist, Nobel Prize laureate (b. 1845)

Charles Louis Alphonse Laveran (18 June 1845 – 18 May 1922) was a French physician who won the Nobel Prize in Physiology or Medicine in 1907 for his discoveries of parasitic protozoans as causative agents of infectious diseases such as malaria and trypanosomiasis. Following his father, Louis Théodore Laveran, he took up military medicine as his profession. He obtained his medical degree from University of Strasbourg in 1867.

At the outbreak of the Franco-Prussian War in 1870, he joined the French Army. At the age of 29 he became Chair of Military Diseases and Epidemics at the École de Val-de-Grâce. At the end of his tenure in 1878 he worked in Algeria, where he made his major achievements. He discovered that the protozoan parasite Plasmodium was responsible for malaria, and that Trypanosoma caused trypanosomiasis or African sleeping sickness. In 1894 he returned to France to serve in various military health services. In 1896 he joined Pasteur Institute as Chief of the Honorary Service, from where he received the Nobel Prize. He donated half of his Nobel prize money to establish the Laboratory of Tropical Medicine at the Pasteur Institute. In 1908, he founded the Société de Pathologie Exotique.

Laveran was elected to French Academy of Sciences in 1893, and was conferred Commander of the National Order of the Legion of Honour in 1912.

May 17th in stamps John Jay, Alfonso XIII of Spain, The Wonderful Wizard of Oz

Here are some events that happened on May 17th. It could be an event or a person that died or was born on that day

1829 Died: John Jay, American politician and diplomat, 1st Chief Justice of the United States (b. 1745)

John Jay (December 12, 1745 – May 17, 1829) was an American statesman, patriot, diplomat, Founding Father, abolitionist, negotiator, and signatory of the Treaty of Paris of 1783. He served as the second Governor of New York and the first Chief Justice of the United States (1789–1795). He directed U.S. foreign policy for much of the 1780s and was an important leader of the Federalist Party after the ratification of the United States Constitution in 1788.

Jay was born into a wealthy family of merchants and New York City government officials of French Huguenot and Dutch descent. He became a lawyer and joined the New York Committee of Correspondence, organizing American opposition to British policies such as the Intolerable Acts in the leadup to the American Revolution. Jay was elected to the Second Continental Congress, and served as President of the Congress. From 1779 to 1782, Jay served as the ambassador to Spain; he persuaded Spain to provide financial aid to the fledgling United States. He also served as a negotiator of the Treaty of Paris, in which Britain recognized American independence. Following the end of the war, Jay served as Secretary of Foreign Affairs, directing United States foreign policy under the Articles of Confederation government. He also served as the first Secretary of State on an interim basis.

A proponent of strong, centralized government, Jay worked to ratify the United States Constitution in New York in 1788. He was a co-author of The Federalist Papers along with Alexander Hamilton and James Madison, and wrote five of the eighty-five essays. After the establishment of the new federal government, Jay was appointed by President George Washington the first Chief Justice of the United States, serving from 1789 to 1795. The Jay Court experienced a light workload, deciding just four cases over six years. In 1794, while serving as Chief Justice, Jay negotiated the highly controversial Jay Treaty with Britain. Jay received a handful of electoral votes in three of the first four presidential elections, but never undertook a serious bid for the presidency.

Jay served as the Governor of New York from 1795 to 1801. Although he successfully passed gradual emancipation legislation as governor of the state, he himself owned five enslaved people as late as 1800. In the waning days of President John Adams's administration, Jay was confirmed by the Senate for another term as Chief Justice, but he declined the position and retired to his farm in Westchester County, New York.

1886 Born: Alfonso XIII of Spain, Spanish monarch (d. 1941)

Alfonso XIII (17 May 1886 – 28 February 1941), also known as El Africano or the African, was King of Spain from 1886 until the proclamation of the Second Republic in 1931. He was a monarch from birth as his father, Alfonso XII, had died the previous year. Alfonso's mother, Maria Christina of Austria, served as regent until he assumed full powers on his sixteenth birthday in 1902.

During Alfonso's reign of the Kingdom of Spain, the country experienced four major problems that contributed to the end of the liberal monarchy: the lack of real political representation of broad social groups; the poor situation of the popular classes, especially peasants; problems arising from the Rif War; and Catalan nationalism. The political and social turbulence that began with the Spanish–American War prevented the turnaround parties from establishing a true liberal democracy, which led to the establishment of the dictatorship of Miguel Primo de Rivera. With the political failure of the dictatorship, Alfonso impelled a return to the democratic normality with the intention of regenerating the regime. Nevertheless, it was abandoned by all political classes, as they felt betrayed by the king's support of the dictatorship of Primo de Rivera.

He left Spain voluntarily after the municipal elections of April 1931, which were taken as a plebiscite on abolishing the monarchy.

1900 – The children's novel The Wonderful Wizard of Oz, by L. Frank Baum, is first published in the United States. The first copy is given to the author's sister.

The Wonderful Wizard of Oz is an American children's novel written by author L. Frank Baum and illustrated by W.W. Denslow, originally published by the George M. Hill Company in May 1900. It has since seen several reprints, most often under the title The Wizard of Oz, which is the title of the popular 1902 Broadway musical adaptation as well as the iconic 1939 live-action film.

The story chronicles the adventures of a young farm girl named Dorothy Gale in the magical Land of Oz after she and her pet dog Toto are swept away from their home in Kansas by a cyclone. The book is one of the best-known stories in American literature and has been widely translated. The Library of Congress has declared it "America's greatest and best-loved homegrown fairytale." Its groundbreaking success, and that of the Broadway musical adapted from the novel led Baum to write thirteen additional Oz books that serve as official sequels to the first story.

In January 1901, George M. Hill Company completed printing the first edition, a total of 10,000 copies, which quickly sold out. It had sold three million copies by the time it entered the public domain in 1956.

May 16th in stamps Vauquelin, Tesla, Django Reinhardt, Tito

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

1763 Born: Louis Nicolas Vauquelin, French pharmacist and chemist (d. 1829)

Prof Louis Nicolas Vauquelin (16 May 1763 – 14 November 1829) was a French pharmacist and chemist. He was the discoverer of both chromium and beryllium.

Contributions to chemistry

At first his work appeared as that of his master and patron, then in their joint names; in 1790 he began to publish on his own, and between that year and 1833 his name is associated with 376 papers. Most of these were simple records of patient and laborious analytical operations, and it is perhaps surprising that among all the substances he analysed he only detected two new elements, beryllium in 1798 in beryl and chromium in 1797 in a red lead ore from Siberia. He also managed to get liquid ammonia at atmospheric pressure. Later with Fourcroy, he identified a metal in a platinum residue they called ‘ptène’, This name ‘ptene’ or ‘ptène’ was reported as an early synonym for osmium.

Either together or successively he held the offices of inspector of mines, professor at the School of Mines and at the Polytechnic School, assayer of gold and silver articles, professor of chemistry in the College de France and at the Jardin des Plantes, member of the Council of Industry and Commerce, commissioner on the pharmacy laws, and finally professor of chemistry to the Medical Faculty, to which he succeeded on Fourcroy's death in 1809. His lectures, which were supplemented with practical laboratory teaching, were attended by many chemists who subsequently attained distinction.

A lesser known contribution and finding of his included the study of hens fed a known amount of mineral. "Having calculated all the lime in oats fed to a hen, found still more in the shells of its eggs. Therefore, there is a creation of matter. In that way, no one knows."

Final achievements, days and legacy

From 1809 he was professor at the University of Paris. In 1816, he was elected a foreign member of the Royal Swedish Academy of Sciences. He was elected to the Chamber of Deputies in 1828. In 1806, working with asparagus, he and Pierre Jean Robiquet (future discoverer of the famous red dye alizarin, then a young chemist and his assistant) isolated the amino acid asparagine, the first one to be discovered. He also discovered pectin and malic acid in apples, and isolated camphoric acid and quinic acid. His death occurred while he was on a visit to his birthplace.

Among his best known works is "Manuel de l'essayeur" (Manual of the assayer).

The plant genus Vauquelinia is named in his honor, as is the Vauquelin, an egg white foam associated with molecular gastronomy, and the mineral vauquelinite, discovered at the same mine as the crocoite from which Vauquelin isolated chromium.

1888 – Nikola Tesla delivers a lecture describing the equipment which will allow efficient generation and use of alternating currents to transmit electric power over long distances.

Nikola Tesla (10 July 1856 – 7 January 1943) was a Serbian-American inventor, electrical engineer, mechanical engineer, and futurist who is best known for his contributions to the design of the modern alternating current (AC) electricity supply system.

Born and raised in the Austrian Empire, Tesla received an advanced education in engineering and physics in the 1870s and gained practical experience in the early 1880s working in telephony and at Continental Edison in the new electric power industry. He emigrated in 1884 to the United States, where he would become a naturalized citizen. He worked for a short time at the Edison Machine Works in New York City before he struck out on his own. With the help of partners to finance and market his ideas, Tesla set up laboratories and companies in New York to develop a range of electrical and mechanical devices. His alternating current (AC) induction motor and related polyphase AC patents, licensed by Westinghouse Electric in 1888, earned him a considerable amount of money and became the cornerstone of the polyphase system which that company would eventually market.

1953 Died: Django Reinhardt, Belgian guitarist and composer (b. 1910)

Jean Reinhardt (23 January 1910 – 16 May 1953), known to all by his Romani nickname Django, was a Belgian-born Romani-French jazz guitarist and composer. He was the first major jazz talent to emerge from Europe and remains the most significant.

With violinist Stéphane Grappelli, Reinhardt formed the Paris-based Quintette du Hot Club de France in 1934. The group was among the first to play jazz that featured the guitar as a lead instrument. Reinhardt recorded in France with many visiting American musicians, including Coleman Hawkins and Benny Carter, and briefly toured the United States with Duke Ellington's orchestra in 1946. He died suddenly of a stroke at the age of 43.

Reinhardt's most popular compositions have become standards within gypsy jazz, including "Minor Swing", "Daphne", "Belleville", "Djangology", "Swing '42", and "Nuages". Jazz guitarist Frank Vignola claims that nearly every major popular-music guitarist in the world has been influenced by Reinhardt. Over the last few decades, annual Django festivals have been held throughout Europe and the U.S., and a biography has been written about his life. In February 2017, the Berlin International Film Festival held the world premiere of the French film Django.

1974 – Josip Broz Tito is elected president for life of Yugoslavia.

Josip Broz (7 May 1892 – 4 May 1980), commonly known as Tito, was a Yugoslav communist revolutionary and statesman, serving in various roles from 1943 until his death in 1980. During World War II, he was the leader of the Partisans, often regarded as the most effective resistance movement in occupied Europe. While his presidency has been criticized as authoritarian and concerns about the repression of political opponents have been raised, Tito has traditionally been seen as a benevolent dictator.

He was a popular public figure both in Yugoslavia and abroad. Viewed as a unifying symbol, his internal policies maintained the peaceful coexistence of the nations of the Yugoslav federation. He gained further international attention as the chief leader of the Non-Aligned Movement, alongside Jawaharlal Nehru of India, Gamal Abdel Nasser of Egypt, and Kwame Nkrumah of Ghana.

Broz was born to a Croat father and Slovene mother in the village of Kumrovec, Austria-Hungary (now in Croatia). Drafted into military service, he distinguished himself, becoming the youngest sergeant major in the Austro-Hungarian Army of that time. After being seriously wounded and captured by the Imperial Russians during World War I, he was sent to a work camp in the Ural Mountains. He participated in some events of the Russian Revolution in 1917 and subsequent Civil War.

Upon his return to the Balkans in 1918, Broz entered the newly established Kingdom of Yugoslavia, where he joined the Communist Party of Yugoslavia (KPJ). He later was elected as General Secretary (later Chairman of the Presidium) of the League of Communists of Yugoslavia (1939–1980). During World War II, after the Nazi invasion of the area, he led the Yugoslav guerrilla movement, the Partisans (1941–1945).

After the war, he was selected as Prime Minister (1944–1963), and President (later President for Life) (1953–1980) of the Socialist Federal Republic of Yugoslavia (SFRY). From 1943 to his death in 1980, Tito held the rank of Marshal of Yugoslavia, serving as the supreme commander of the Yugoslav military, the Yugoslav People's Army (JNA). With a highly favourable reputation abroad in both Cold War blocs, he received some 98 foreign decorations, including the Legion of Honour and the Order of the Bath.

Tito was the chief architect of the second Yugoslavia, a socialist federation that lasted from November 1943 until April 1992. Despite being one of the founders of Cominform, he became the first Cominform member to defy Soviet hegemony in 1948. He was the only leader in Joseph Stalin's time to leave Cominform and begin with his country's own socialist program, which contained elements of market socialism. Economists active in the former Yugoslavia, including Czech-born Jaroslav Vanek and Yugoslav-born Branko Horvat, promoted a model of market socialism that was dubbed the Illyrian model. Firms were socially owned by their employees and structured on workers' self-management; they competed in open and free markets.

Tito built a very powerful cult of personality around himself, which was maintained by the League of Communists of Yugoslavia after his death.

Tito managed to keep ethnic tensions under control by delegating as much power as possible to each republic. The 1974 Yugoslav Constitution defined SFR Yugoslavia as a "federal republic of equal nations and nationalities, freely united on the principle of brotherhood and unity in achieving specific and common interest." Each republic was also given the right to self-determination and secession if done through legal channels. Lastly, Kosovo and Vojvodina, the two constituent provinces of Serbia, received substantially increased autonomy, including de facto veto power in the Serbian parliament.

Ten years after his death, Communism collapsed in Eastern Europe, and Yugoslavia descended into civil war.
