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 April 29th. It could be an event or a person that died or was born on that day

1676 Died: Michiel de Ruyter, Dutch admiral (b. 1607)

Michiel Adriaenszoon de Ruyter (24 March 1607 – 29 April 1676) was a Dutch admiral. Widely celebrated and regarded as one of the most skilled admirals in history, De Ruyter is arguably most famous for his achievements with the Dutch Navy during the Anglo-Dutch Wars. He fought the English and French forces and scored several critical victories, with the Raid on the Medway being the most famous among them.

Often dubbed a Dutch folk hero, De Ruyter is one of a few select officers in the history of the Dutch navy to hold the title of the lieutenant admiral (Dutch: luitenant-admiraal). Reportedly beloved by his subordinates and seamen, De Ruyter was commonly nicknamed Bestevaêr (Middle Dutch for "grandfather") during his service, a nickname that is sometimes still used to refer to him in Dutch media.

1770 – James Cook arrives in Australia at Botany Bay, which he names.

Captain James Cook (7 November 1728 – 14 February 1779) was a British explorer, navigator, cartographer, and captain in the Royal Navy. He made detailed maps of Newfoundland prior to making three voyages to the Pacific Ocean, during which he achieved the first recorded European contact with the eastern coastline of Australia and the Hawaiian Islands, and the first recorded circumnavigation of New Zealand.

Cook joined the British merchant navy as a teenager and joined the Royal Navy in 1755. He saw action in the Seven Years' War and subsequently surveyed and mapped much of the entrance to the Saint Lawrence River during the siege of Quebec, which brought him to the attention of the Admiralty and Royal Society. This acclaim came at a crucial moment in his career and the direction of British overseas exploration, and led to his commission in 1766 as commander of HM Bark Endeavour for the first of three Pacific voyages.

In these voyages, Cook sailed thousands of miles across largely uncharted areas of the globe. He mapped lands from New Zealand to Hawaii in the Pacific Ocean in greater detail and on a scale not previously charted by Western explorers. He surveyed and named features, and recorded islands and coastlines on European maps for the first time. He displayed a combination of seamanship, superior surveying and cartographic skills, physical courage, and an ability to lead men in adverse conditions.

Cook was attacked and killed in 1779 during his third exploratory voyage in the Pacific while attempting to kidnap the Island of Hawaii's monarch, Kalaniʻōpuʻu, in order to reclaim a cutter stolen from one of his ships. He left a legacy of scientific and geographical knowledge that influenced his successors well into the 20th century, and numerous memorials worldwide have been dedicated to him.

1818 Born: Alexander II of Russia (d. 1881)

Alexander II (29 April 1818 – 13 March 1881) was the emperor of Russia from 2 March 1855 until his assassination on 13 March 1881. He was also the king of Poland and the grand duke of Finland.

Alexander's most significant reform as emperor was emancipation of Russia's serfs in 1861, for which he is known as Alexander the Liberator. The tsar was responsible for other reforms, including reorganizing the judicial system, setting up elected local judges, abolishing corporal punishment, promoting local self-government through the zemstvo system, imposing universal military service, ending some privileges of the nobility, and promoting university education. After an assassination attempt in 1866, Alexander adopted a somewhat more reactionary stance until his death.

Alexander pivoted towards foreign policy and sold Alaska to the United States in 1867, fearing the remote colony would fall into British hands if there were another war. He sought peace, moved away from bellicose France when Napoleon III fell in 1871, and in 1872 joined with Germany and Austria in the League of the Three Emperors that stabilized the European situation. Despite his otherwise pacifist foreign policy, he fought a brief war with the Ottoman Empire in 1877–78, pursued further expansion into Siberia and the Caucasus, and conquered Turkestan. Although disappointed by the results of the Congress of Berlin in 1878, Alexander abided by that agreement. Among his greatest domestic challenges was an uprising in Poland in 1863, to which he responded by stripping that land of its separate constitution and incorporating it directly into Russia. Alexander was proposing additional parliamentary reforms to counter the rise of nascent revolutionary and anarchistic movements when he was assassinated in 1881.

Here are some events that happened on April 24th. It could be an event or a person that died or was born on that day

1533 Born: William I of Orange, founding father of the Netherlands (d. 1584)

William the Silent (24 April 1533 – 10 July 1584), also known as William the Taciturn (translated from Dutch: Willem de Zwijger), or William of Orange (Dutch: Willem van Oranje), was the main leader of the Dutch Revolt against the Spanish Habsburgs that set off the Eighty Years' War (1568–1648) and resulted in the formal independence of the United Provinces in 1581. Born into the House of Nassau, he became Prince of Orange in 1544 and is thereby the founder of the Orange-Nassau branch and the ancestor of the monarchy of the Netherlands. In the Netherlands, he is also known as Father of the Fatherland (Pater Patriae) (Dutch: Vader des Vaderlands).

A wealthy nobleman, William originally served the Habsburgs as a member of the court of Margaret of Parma, governor of the Spanish Netherlands. Unhappy with the centralisation of political power away from the local estates and with the Spanish persecution of Dutch Protestants, William joined the Dutch uprising and turned against his former masters. The most influential and politically capable of the rebels, he led the Dutch to several successes in the fight against the Spanish. Declared an outlaw by the Spanish king in 1580, he was assassinated by Balthasar Gérard (also written as "Gerardts") in Delft in 1584.

1731 Died: Daniel Defoe, English journalist, novelist, and spy (b. 1660)

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.

1953 – Winston Churchill is knighted by Queen Elizabeth II.

Sir Winston Leonard Spencer Churchill (30 November 1874 – 24 January 1965) was a British statesman, army officer, and writer. He was Prime Minister of the United Kingdom from 1940 to 1945, when he led the country to victory in the Second World War, and again from 1951 to 1955. Apart from two years between 1922 and 1924, Churchill was a Member of Parliament (MP) from 1900 to 1964 and represented a total of five constituencies. Ideologically an economic liberal and imperialist, he was for most of his career a member of the Conservative Party, as leader from 1940 to 1955. He was a member of the Liberal Party from 1904 to 1924.

Of mixed English and American parentage, Churchill was born in Oxfordshire to a wealthy, aristocratic family. He joined the British Army in 1895 and saw action in British India, the Anglo-Sudan War, and the Second Boer War, gaining fame as a war correspondent and writing books about his campaigns. Elected a Conservative MP in 1900, he defected to the Liberals in 1904. In H. H. Asquith's Liberal government, Churchill served as President of the Board of Trade and Home Secretary, championing prison reform and workers' social security. As First Lord of the Admiralty during the First World War, he oversaw the Gallipoli Campaign but, after it proved a disaster, he was demoted to Chancellor of the Duchy of Lancaster. He resigned in November 1915 and joined the Royal Scots Fusiliers on the Western Front for six months. In 1917, he returned to government under David Lloyd George and served successively as Minister of Munitions, Secretary of State for War, Secretary of State for Air, and Secretary of State for the Colonies, overseeing the Anglo-Irish Treaty and British foreign policy in the Middle East. After two years out of Parliament, he served as Chancellor of the Exchequer in Stanley Baldwin's Conservative government, returning the pound sterling in 1925 to the gold standard at its pre-war parity, a move widely seen as creating deflationary pressure and depressing the UK economy.

Out of office during the 1930s, Churchill took the lead in calling for British rearmament to counter the growing threat of militarism in Nazi Germany. At the outbreak of the Second World War he was re-appointed First Lord of the Admiralty. In May 1940, he became Prime Minister, replacing Neville Chamberlain. Churchill oversaw British involvement in the Allied war effort against the Axis powers, resulting in victory in 1945. After the Conservatives' defeat in the 1945 general election, he became Leader of the Opposition. Amid the developing Cold War with the Soviet Union, he publicly warned of an "iron curtain" of Soviet influence in Europe and promoted European unity. Re-elected Prime Minister in 1951, his second term was preoccupied with foreign affairs, especially Anglo-American relations and, despite ongoing decolonisation, preservation of the British Empire. Domestically, his government emphasised house-building and developed a nuclear weapon. In declining health, Churchill resigned as Prime Minister in 1955, although he remained an MP until 1964. Upon his death in 1965, he was given a state funeral.

Widely considered one of the 20th century's most significant figures, Churchill remains popular in the UK and Western world, where he is seen as a victorious wartime leader who played an important role in defending Europe's liberal democracy against the spread of fascism. Also praised as a social reformer and writer, among his many awards was the Nobel Prize in Literature. Conversely, he has been criticised for some wartime events, notably the 1945 bombing of Dresden, and for his imperialist views and comments on race.

April 23rd in stamps Maarten Tromp, Shakespeare, Max Planck

Here are some events that happened on April 23rd. It could be an event or a person that died or was born on that day

1598 Born: Maarten Tromp, Dutch admiral (d. 1653)

Maarten Harpertszoon Tromp (also written as Maerten Tromp; 23 April 1598 – 10 August 1653) was a Dutch army general and admiral in the Dutch navy.

In 1637, Tromp was promoted from captain to Lieutenant-Admiral of Holland and West Frisia in 1637, following the dismissal of Lieutenant-Admiral Philips van Dorp, Vice-Admiral Jasper Liefhebber, and other flag officers due to incompetence. Although formally ranking under the Admiral-General Frederick Henry of Orange, he was the de facto supreme commander of the Dutch fleet, as the stadtholders never fought at sea. Tromp was mostly occupied with blockading the privateer port of Dunkirk. Both Tromp and Witte de With, who was named as Vice-Admiral, had been born in Den Briel and served as flag captains of Piet Heyn.

In 1639, during the Dutch struggle for independence from Spain, Tromp defeated a large Spanish fleet bound for Flanders at the Battle of the Downs, marking the end of Spanish naval power. In a preliminary battle, the Action of 18 September 1639, Tromp was the first fleet commander known for the deliberate use of line of battle tactics. His flagship in this period was the Aemilia.

In 1643 the subject was the center of a parliamentary investigation of naval intrigue with the Queen of England and the Prince of Orange who had allegedly instructed the Vice-Admiral to allow passage of two frigates purchased by English royalists in Dunkirk.

In the First Anglo-Dutch War of 1652 to 1653, Tromp commanded the Dutch fleet in the battles of Dover, Dungeness, Portland, the Gabbard and Scheveningen. In the latter, he was killed by a sharpshooter in the rigging of William Penn's ship. His acting flag captain, Egbert Bartholomeusz Kortenaer, on the Brederode kept up fleet morale by not lowering Tromp's standard, pretending Tromp was still alive.

Tromp's death was a severe blow to the Dutch navy but also to the Orangists, who sought the defeat of the Commonwealth of England and the restoration of the Stuart monarchy. Republican influence strengthened after Scheveningen, which led to peace negotiations with the Commonwealth, culminating in the Treaty of Westminster.

During his career, his main rival was Vice-Admiral Witte de With, who also served the Admiralty of Rotterdam (de Maze) from 1637. De With temporarily replaced him as supreme commander for the Battle of Kentish Knock. Tromp's successor was Lieutenant-Admiral Jacob van Wassenaer Obdam.

1616 Died: William Shakespeare, English playwright and poet (b. 1564)

William Shakespeare (bapt. 26 April 1564 – 23 April 1616) was an English playwright, poet, and actor, widely regarded as the greatest writer in the English language and the world's greatest dramatist. He is often called England's national poet and the "Bard of Avon" (or simply "the Bard"). His extant works, including collaborations, consist of some 39 plays, 154 sonnets, three long narrative poems, and a few other verses, some of uncertain authorship. His plays have been translated into every major living language and are performed more often than those of any other playwright. They also continue to be studied and reinterpreted.

Shakespeare was born and raised in Stratford-upon-Avon, Warwickshire. At the age of 18, he married Anne Hathaway, with whom he had three children: Susanna and twins Hamnet and Judith. Sometime between 1585 and 1592, he began a successful career in London as an actor, writer, and part-owner of a playing company called the Lord Chamberlain's Men, later known as the King's Men. At age 49 (around 1613), he appears to have retired to Stratford, where he died three years later. Few records of Shakespeare's private life survive; this has stimulated considerable speculation about such matters as his physical appearance, his sexuality, his religious beliefs, and whether the works attributed to him were written by others.

Shakespeare produced most of his known works between 1589 and 1613. His early plays were primarily comedies and histories and are regarded as some of the best work produced in these genres. He then wrote mainly tragedies until 1608, among them Hamlet, Romeo and Juliet, Othello, King Lear, and Macbeth, all considered to be among the finest works in the English language. In the last phase of his life, he wrote tragicomedies (also known as romances) and collaborated with other playwrights.

Many of Shakespeare's plays were published in editions of varying quality and accuracy in his lifetime. However, in 1623, two fellow actors and friends of Shakespeare's, John Heminges and Henry Condell, published a more definitive text known as the First Folio, a posthumous collected edition of Shakespeare's dramatic works that included all but two of his plays. The volume was prefaced with a poem by Ben Jonson, in which Jonson presciently hailed Shakespeare in a now-famous quote as "not of an age, but for all time".

1858 Born: Max Planck, German physicist and academic, Nobel Prize laureate (d. 1947)

Max Karl Ernst Ludwig Planck (23 April 1858 – 4 October 1947) was a German theoretical physicist whose discovery of energy quanta won him the Nobel Prize in Physics in 1918.

Planck made many contributions to theoretical physics, but his fame as a physicist rests primarily on his role as the originator of quantum theory, which revolutionized human understanding of atomic and subatomic processes. In 1948, the German scientific institution the Kaiser Wilhelm Society (of which Planck was twice president) was renamed the Max Planck Society (MPS). The MPS now includes 83 institutions representing a wide range of scientific directions.

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

1521 – Trial of Martin Luther over his teachings begins during the assembly of the Diet of Worms. Initially intimidated, he asks for time to reflect before answering and is given a stay of one day.

Martin Luther (10 November 1483 – 18 February 1546) was a German professor of theology, composer, priest, monk, and a seminal figure in the Protestant Reformation.

Luther was ordained to the priesthood in 1507. He came to reject several teachings and practices of the Roman Catholic Church; in particular, he disputed the view on indulgences. Luther proposed an academic discussion of the practice and efficacy of indulgences in his Ninety-five Theses of 1517. His refusal to renounce all of his writings at the demand of Pope Leo X in 1520 and the Holy Roman Emperor Charles V at the Diet of Worms in 1521 resulted in his excommunication by the pope and condemnation as an outlaw by the Holy Roman Emperor.

Luther taught that salvation and, consequently, eternal life are not earned by good deeds but are received only as the free gift of God's grace through the believer's faith in Jesus Christ as redeemer from sin. His theology challenged the authority and office of the Pope by teaching that the Bible is the only source of divinely revealed knowledge, and opposed sacerdotalism by considering all baptized Christians to be a holy priesthood. Those who identify with these, and all of Luther's wider teachings, are called Lutherans, though Luther insisted on Christian or Evangelical (German: evangelisch) as the only acceptable names for individuals who professed Christ.

His translation of the Bible into the German vernacular (instead of Latin) made it more accessible to the laity, an event that had a tremendous impact on both the church and German culture. It fostered the development of a standard version of the German language, added several principles to the art of translation, and influenced the writing of an English translation, the Tyndale Bible. His hymns influenced the development of singing in Protestant churches. His marriage to Katharina von Bora, a former nun, set a model for the practice of clerical marriage, allowing Protestant clergy to marry.

In two of his later works, Luther expressed antagonistic views towards Jews. His rhetoric was not directed at Jews alone, but also towards Roman Catholics, Anabaptists, and nontrinitarian Christians. Luther died in 1546 with Pope Leo X's excommunication still effective.

1524 – Giovanni da Verrazzano reaches New York harbor.

Giovanni da Verrazzano (1485–1528) was a Florentine explorer of North America, in the service of King Francis I of France.

He is renowned as the first European to explore the Atlantic coast of North America between Florida and New Brunswick in 1524, including New York Bay and Narragansett Bay.

Despite his discoveries, Verrazzano's reputation did not proliferate as much as other explorers of that era. For example, Verrazzano gave the European name Francesca to the new land that he had seen, in accordance with contemporary practices, after the French king in whose name he sailed. That and other names that he bestowed on features that he discovered have not survived. He had the misfortune of making major discoveries in the same three years (1519 to 1521) that the dramatic Conquest of Mexico and Ferdinand Magellan's circumnavigation of the world occurred. Magellan himself did not complete his voyage, but his publicist Antonio Pigafetta did so, and Spanish publicity outweighed the news of the French voyage.

In the 19th and the early 20th centuries, there was a great debate in the United States about the authenticity of the letters that he wrote to Francis I to describe the geography, flora, fauna, and native population of the east coast of North America. Others thought that they were authentic, almost universally the current opinion, particularly after the discovery of a letter signed by Francis I, which referred to Verrazzano's letter.

Verrazzano's reputation was particularly obscure in New York City, where the 1609 voyage of Henry Hudson on behalf of the Dutch Republic came to be regarded as the de facto start of European exploration of New York. It was only by a great effort in the 1950s and 1960s that Verrazzano's name and reputation were re-established as the European discoverer of the harbor, during an effort to name the newly built Narrows bridge after him.

1790 Died: Benjamin Franklin, American inventor, publisher, and politician, 6th President of Pennsylvania (b. 1706)

Benjamin Franklin (January 17, 1706 - April 17, 1790) was a British American polymath and one of the Founding Fathers of the United States. Franklin was a leading writer, printer, political philosopher, politician, Freemason, postmaster, scientist, inventor, humorist, civic activist, statesman, and diplomat. As a scientist, he was a major figure in the American Enlightenment and the history of physics for his discoveries and theories regarding electricity. As an inventor, he is known for the lightning rod, bifocals, and the Franklin stove, among other inventions. He founded many civic organizations, including the Library Company, Philadelphia's first fire department, and the University of Pennsylvania.

Franklin earned the title of "The First American" for his early and indefatigable campaigning for colonial unity, initially as an author and spokesman in London for several colonies. As the first United States ambassador to France, he exemplified the emerging American nation. Franklin was foundational in defining the American ethos as a marriage of the practical values of thrift, hard work, education, community spirit, self-governing institutions, and opposition to authoritarianism both political and religious, with the scientific and tolerant values of the Enlightenment. In the words of historian Henry Steele Commager, "In a Franklin could be merged the virtues of Puritanism without its defects, the illumination of the Enlightenment without its heat." To Walter Isaacson, this makes Franklin "the most accomplished American of his age and the most influential in inventing the type of society America would become."

Franklin became a successful newspaper editor and printer in Philadelphia, the leading city in the colonies, publishing the Pennsylvania Gazette at the age of 23. He became wealthy publishing this and Poor Richard's Almanack, which he authored under the pseudonym "Richard Saunders". After 1767, he was associated with the Pennsylvania Chronicle, a newspaper that was known for its revolutionary sentiments and criticisms of the policies of the British Parliament and the Crown.

He pioneered and was the first president of Academy and College of Philadelphia which opened in 1751 and later became the University of Pennsylvania. He organized and was the first secretary of the American Philosophical Society and was elected president in 1769. Franklin became a national hero in America as an agent for several colonies when he spearheaded an effort in London to have the Parliament of Great Britain repeal the unpopular Stamp Act. An accomplished diplomat, he was widely admired among the French as American minister to Paris and was a major figure in the development of positive Franco–American relations. His efforts proved vital for the American Revolution in securing shipments of crucial munitions from France.

He was promoted to deputy postmaster-general for the British colonies on August 10, 1753, having been Philadelphia postmaster for many years, and this enabled him to set up the first national communications network. During the revolution, he became the first United States postmaster general. He was active in community affairs and colonial and state politics, as well as national and international affairs. From 1785 to 1788, he served as governor of Pennsylvania. He initially owned and dealt in slaves but, by the late 1750s, he began arguing against slavery, became an abolitionist, and promoted education and the integration of blacks in American Society.

His life and legacy of scientific and political achievement, and his status as one of America's most influential Founding Fathers, have seen Franklin honored more than two centuries after his death on the fifty-cent piece, the $100 bill, warships, and the names of many towns, counties, educational institutions, and corporations, as well as numerous cultural references.

1907 – The Ellis Island immigration center processes 11,747 people, more than on any other day.

Ellis Island is a federally owned island in New York Harbor that was the United States' busiest immigrant inspection station. From 1892 to 1924, approximately 12 million immigrants arriving at the Port of New York and New Jersey were processed there under federal law. Today, it is part of the Statue of Liberty National Monument, accessible to the public only by ferry. The north side of the island is the site of the main building, now a national museum of immigration. The south side of the island, including the Ellis Island Immigrant Hospital, is only open to the public through guided tours.

In the 19th century, Ellis Island was the site of Fort Gibson and later became a naval magazine. The first inspection station opened in 1892 and was destroyed by fire in 1897. The second station opened in 1900 and housed facilities for medical quarantines as well as processing immigrants. After 1924, Ellis Island was used primarily as a detention center for migrants. During both World War I and World War II its facilities were also used by the United States military to detain prisoners of war. Following the immigration station's closure, the buildings languished for several years until they partially reopened in 1976. The main building and adjacent structures were completely renovated in 1990.

The 27.5-acre (11.1 ha) island was greatly expanded by land reclamation between the late 1890s and the 1930s. Jurisdictional disputes between New Jersey and New York persisted until the 1998 U.S. Supreme Court ruling in New Jersey v. New York.

1942 Died: Jean Baptiste Perrin, French-American physicist and chemist, Nobel Prize laureate (b. 1870)

Jean Baptiste Perrin  (30 September 1870 – 17 April 1942) was a French physicist who, in his studies of the Brownian motion of minute particles suspended in liquids, verified Albert Einstein’s explanation of this phenomenon and thereby confirmed the atomic nature of matter (sedimentation equilibrium). For this achievement he was honoured with the Nobel Prize for Physics in 1926.

In 1895, Perrin showed that cathode rays were of negative electric charge in nature. He determined Avogadro's number (now known as the Avogadro constant) by several methods. He explained solar energy as due to the thermonuclear reactions of hydrogen.

After Albert Einstein published (1905) his theoretical explanation of Brownian motion in terms of atoms, Perrin did the experimental work to test and verify Einstein's predictions, thereby settling the century-long dispute about John Dalton's atomic theory. Carl Benedicks argued Perrin should receive the Nobel Prize in Physics; Perrin received the award in 1926 for this and other work on the discontinuous structure of matter, which put a definite end to the long struggle regarding the question of the physical reality of molecules.

Perrin was the author of a number of books and dissertations. Most notable of his publications were: "Rayons cathodiques et rayons X"; "Les Principes"; "Electrisation de contact"; "Réalité moléculaire"; "Matière et Lumière"; "Lumière et Reaction chimique".

Perrin was also the recipient of numerous prestigious awards including the Joule Prize of the Royal Society in 1896 and the La Caze Prize of the French Academy of Sciences. He was twice appointed a member of the Solvay Committee at Brussels in 1911 and in 1921. He also held memberships with the Royal Society of London and with the Academies of Sciences of Belgium, Sweden, Turin, Prague, Romania and China. He became a Commander of the Legion of Honour in 1926 and was made Commander of the Order of Léopold (Belgium).

In 1919, Perrin proposed that nuclear reactions can provide the source of energy in stars. He realized that the mass of a helium atom is less than that of four atoms of hydrogen, and that the mass-energy equivalence of Einstein implies that the nuclear fusion (4 H → He) could liberate sufficient energy to make stars shine for billions of years. A similar theory was first proposed by American chemist William Draper Harkins in 1915. It remained for Hans Bethe and Carl Friedrich von Weizsäcker to determine the detailed mechanism of stellar nucleosynthesis during the 1930s.

In 1927, he founded the Institut de Biologie Physico-Chimique together with chemist André Job and physiologist André Mayer. Funding was provided by Edmond James de Rothschild. In 1937, Perrin established the Palais de la Découverte, a science museum in Paris.

Perrin is considered the founding father of the National Centre for Scientific Research (Centre National de la Recherche Scientifique (CNRS)). Following a petition by Perrin signed by over 80 scientists, among them eight Nobel Prize laureates, the French education minister set up the Conseil Supérieur de la Recherche Scientifique (French National Research Council) in April 1933. In 1936, Perrin, now an undersecretary for research, founded the Service Central de la Recherche Scientifique (French Central Agency for Scientific Research). Both institutions were merged under the CNRS umbrella on October 19, 1939.

His notable students include Pierre Victor Auger. Jean Perrin was the father of Francis Perrin, also a physicist.

Here are some events that happened on March 30th. It could be an event or a person that died or was born on that day

1432 Born: Mehmed the Conqueror, Ottoman sultan (d. 1481)

Mehmed II (30 March 1432 – 3 May 1481), commonly known as Mehmed the Conqueror (Turkish: Fatih Sultan Mehmet), was an Ottoman Sultan who ruled from August 1444 to September 1446, and then later from February 1451 to May 1481. In Mehmed II's first reign, he defeated the crusade led by John Hunyadi after the Hungarian incursions into his country broke the conditions of the truce Peace of Szeged. When Mehmed II ascended the throne again in 1451 he strengthened the Ottoman navy and made preparations to attack Constantinople.

At the age of 21, he conquered Constantinople (modern-day Istanbul) and brought an end to the Byzantine Empire. After the conquest Mehmed claimed the title "Caesar" of the Roman Empire (Qayser-i Rûm), based on the fact that Constantinople had been the seat and capital of the surviving Eastern Roman Empire since its consecration in 330 AD by Emperor Constantine I. The claim was only recognized by the Patriarchate of Constantinople. Nonetheless, Mehmed II viewed the Ottoman state as a continuation of the Roman Empire for the remainder of his life, seeing himself as "continuing" the Empire rather than "replacing" it. This assertion was eventually abandoned by his successors.

Mehmed continued his conquests in Anatolia with its reunification and in Southeast Europe as far west as Bosnia. At home he made many political and social reforms, encouraged the arts and sciences, and by the end of his reign, his rebuilding program had changed the city into a thriving imperial capital. He is considered a hero in modern-day Turkey and parts of the wider Muslim world. Among other things, Istanbul's Fatih district, Fatih Sultan Mehmet Bridge and Fatih Mosque are named after him.

1853 Born: Vincent van Gogh, Dutch-French painter and illustrator (d. 1890)

Vincent Willem van Gogh (30 March 1853 – 29 July 1890) was a Dutch post-impressionist painter who is among the most famous and influential figures in the history of Western art. In just over a decade he created about 2,100 artworks, including around 860 oil paintings, most of them in the last two years of his life. They include landscapes, still lifes, portraits and self-portraits, and are characterised by bold colours and dramatic, impulsive and expressive brushwork that contributed to the foundations of modern art. He was not commercially successful, and his suicide at 37 followed years of mental illness and poverty


On 27 July 1890, aged 37, Van Gogh shot himself in the chest with a 7mm Lefaucheux à broche revolver. There were no witnesses and he died 30 hours after the incident. The shooting may have taken place in the wheat field in which he had been painting, or a local barn. The bullet was deflected by a rib and passed through his chest without doing apparent damage to internal organs – probably stopped by his spine. He was able to walk back to the Auberge Ravoux, where he was attended to by two doctors, but without a surgeon present the bullet could not be removed. The doctors tended to him as best they could, then left him alone in his room, smoking his pipe. The following morning Theo rushed to his brother's side, finding him in good spirits. But within hours Vincent began to fail, suffering from an untreated infection resulting from the wound. He died in the early hours of 29 July. According to Theo, Vincent's last words were: "The sadness will last forever"

1863 – Danish prince Wilhelm Georg is chosen as King George of Greece.

George I (24 December 1845 – 18 March 1913) was King of Greece from 30 March 1863 until his assassination in 1913.

Originally a Danish prince, he was born in Copenhagen, and seemed destined for a career in the Royal Danish Navy. He was only 17 years old when he was elected king by the Greek National Assembly, which had deposed the unpopular Otto. His nomination was both suggested and supported by the Great Powers: the United Kingdom of Great Britain and Ireland, the Second French Empire and the Russian Empire. He married Grand Duchess Olga Constantinovna of Russia in 1867, and became the first monarch of a new Greek dynasty. Two of his sisters, Alexandra and Dagmar, married into the British and Russian royal families. Edward VII of the United Kingdom and Alexander III of Russia were his brothers-in-law, and George V, Nicholas II, Christian X of Denmark and Haakon VII of Norway were his nephews.

George's reign of almost 50 years (the longest in modern Greek history) was characterized by territorial gains as Greece established its place in pre-World War I Europe. Britain ceded the Ionian Islands peacefully in 1864, while Thessaly was annexed from the Ottoman Empire after the Russo-Turkish War (1877–1878). Greece was not always successful in its territorial ambitions; it was defeated in the Greco-Turkish War (1897). During the First Balkan War, after Greek troops had captured much of Greek Macedonia, George was assassinated in Thessaloniki. Compared with his own long tenure, the reigns of his successors Constantine I, Alexander, and George II proved short and insecure.

1867 – Alaska is purchased from Russia for $7.2 million, about 2-cent/acre ($4.19/km2), by United States Secretary of State William H. Seward. 

The Alaska Purchase (Russian: Продажа Аляски, romanized: Prodazha Aliaski, meaning "Sale of Alaska") was the United States' acquisition of Alaska from the Russian Empire. Alaska was formally transferred to the United States on October 18, 1867, through a treaty ratified by the United States Senate.

Russia had established a presence in North America during the first half of the 18th century, but few Russians ever settled in Alaska. In the aftermath of the Crimean War, Russian Tzar Alexander II began exploring the possibility of selling Alaska, which would be difficult to defend in any future war from being conquered by Russia's main archrival, the United Kingdom. Following the end of the American Civil War, U.S. Secretary of State William Seward entered into negotiations with Russian minister Eduard de Stoeckl for the purchase of Alaska. Seward and Stoeckl agreed to a treaty on March 30, 1867, and the treaty was ratified by the United States Senate by a wide margin.

The purchase added 586,412 square miles (1,518,800 km2) of new territory to the United States for the cost of $7.2 million 1867 dollars (2 cents per acre). In modern terms, the cost was equivalent to $132 million in 2019 dollars or $0.37 per acre. Reactions to the purchase in the United States were mostly positive, as many believed possession of Alaska would serve as a base to expand American trade in Asia. Some opponents labeled the purchase as "Seward's Folly", or "Seward's Icebox", as they contended that the United States had acquired useless land. Nearly all Russian settlers left Alaska in the aftermath of the purchase; Alaska would remain sparsely populated until the Klondike Gold Rush began in 1896. Originally organized as the Department of Alaska, the area was renamed the District of Alaska (1884) and the Alaska Territory (1912) before becoming the modern State of Alaska in 1959.

1912 Died: Karl May, German author (b. 1842)

Karl Friedrich May (25 February 1842 – 30 March 1912) was a German author. He is best known for his travel novels set on one hand in the American Old West with Winnetou and Old Shatterhand as main protagonists and on the other hand in the Orient and Middle East with Kara Ben Nemsi and Hadschi Halef Omar. May also wrote novels set in Latin America and Germany, poetry, a play, and composed music; he was a proficient player of several musical instruments. Many of his works were adapted for film, stage, audio dramas and comics. Later in his career, May turned to philosophical and spiritual genres. He is one of the best-selling German writers of all time, with about 200,000,000 copies worldwide.
