May 24th in stamps Copernicus, Queen Victoria, Brooklyn Bridge

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

1543 Died: Nicolaus Copernicus, Polish mathematician and astronomer (b. 1473)

Nicolaus Copernicus (19 February 1473 – 24 May 1543) was a Renaissance-era mathematician, astronomer, and Catholic canon who formulated a model of the universe that placed the Sun rather than Earth at the center of the universe. In all likelihood, Copernicus developed his model independently of Aristarchus of Samos, an ancient Greek astronomer who had formulated such a model some eighteen centuries earlier.

The publication of Copernicus' model in his book De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, was a major event in the history of science, triggering the Copernican Revolution and making a pioneering contribution to the Scientific Revolution.

Copernicus was born and died in Royal Prussia, a region that had been part of the Kingdom of Poland since 1466. A polyglot and polymath, he obtained a doctorate in canon law and was a mathematician, astronomer, physician, classics scholar, translator, governor, diplomat, and economist. In 1517 he derived a quantity theory of money—a key concept in economics—and in 1519 he formulated an economic principle that later came to be called Gresham's law.

1819 Born: Queen Victoria of the United Kingdom (d. 1901)

Victoria (Alexandrina Victoria; 24 May 1819 – 22 January 1901) was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death. She adopted the additional title of Empress of India on 1 May 1876. Known as the Victorian era, her reign of 63 years and seven months was longer than that of any of her predecessors. It was a period of industrial, cultural, political, scientific, and military change within the United Kingdom, and was marked by a great expansion of the British Empire.

Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn (the fourth son of King George III), and Princess Victoria of Saxe-Coburg-Saalfeld. After both the Duke and his father died in 1820, she was raised under close supervision by her mother and her comptroller, John Conroy. She inherited the throne aged 18 after her father's three elder brothers died without surviving legitimate issue. Though a constitutional monarch, privately, Victoria attempted to influence government policy and ministerial appointments; publicly, she became a national icon who was identified with strict standards of personal morality.

Victoria married her cousin Prince Albert of Saxe-Coburg and Gotha in 1840. Their children married into royal and noble families across the continent, earning Victoria the sobriquet "the grandmother of Europe" and spreading haemophilia in European royalty. After Albert's death in 1861, Victoria plunged into deep mourning and avoided public appearances. As a result of her seclusion, republicanism in the United Kingdom temporarily gained strength, but in the latter half of her reign, her popularity recovered. Her Golden and Diamond Jubilees were times of public celebration. She died on the Isle of Wight in 1901. The last British monarch of the House of Hanover, she was succeeded by her son Edward VII of the House of Saxe-Coburg and Gotha.

1883 – The Brooklyn Bridge in New York City is opened to traffic after 14 years of construction.

John Augustus Roebling (born Johann August Röbling; June 12, 1806 – July 22, 1869) was a German-born American civil engineer. He designed and built wire rope suspension bridges, in particular the Brooklyn Bridge, which has been designated as a National Historic Landmark and a National Historic Civil Engineering Landmark.

The Brooklyn Bridge is a hybrid cable-stayed/suspension bridge in New York City, spanning the East River between the boroughs of Manhattan and Brooklyn. Opened on May 24, 1883, the Brooklyn Bridge was the first fixed crossing across the East River. It was also the longest suspension bridge in the world at the time, with a main span of 1,595.5 feet (486.3 m) and a deck height of 127 ft (38.7 m) above mean high water. The span was originally called the New York and Brooklyn Bridge or the East River Bridge but was officially renamed the Brooklyn Bridge in 1915.

Proposals for a bridge connecting Manhattan and Brooklyn were first made in the early 19th century, which eventually led to the construction of the current span, designed by John A. Roebling. His son Washington Roebling oversaw the construction and contributed further design work, assisted by the latter's wife, Emily Warren Roebling. While construction started in 1870, numerous controversies and the novelty of the designed construction process caused the actual construction to be prolonged over thirteen years. Since opening, the Brooklyn Bridge has undergone several reconfigurations, having carried horse-drawn vehicles and elevated railway lines until 1950. To alleviate increasing traffic flows, additional bridges and tunnels were built across the East River. Following gradual deterioration, the Brooklyn Bridge has been renovated several times, including in the 1950s, 1980s, and 2010s.

The Brooklyn Bridge is the southernmost of four toll-free vehicular bridges connecting Manhattan Island and Long Island, with the Manhattan, Williamsburg, and Queensboro bridges to the north. Only passenger vehicles and pedestrian and bicycle traffic are permitted. A major tourist attraction since its opening, the Brooklyn Bridge has become an icon of New York City. Over the years, the bridge has been used as the location of various stunts and performances, as well as several crimes and attacks. The Brooklyn Bridge has been designated a National Historic Landmark, a New York City landmark, and a National Historic Civil Engineering Landmark.

May 23rd in stamps Carl Linnaeus, South Carolina statehood, Otto Lilienthal

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

1707 Born: Carl Linnaeus, Swedish botanist, physician, and zoologist (d. 1778)

Carl Linnaeus (23 May 1707 – 10 January 1778), also known after his ennoblement as Carl von Linné, was a Swedish botanist, zoologist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin, and his name is rendered in Latin as Carolus Linnæus (after 1761 Carolus a Linné).

Linnaeus was born in the countryside of Småland in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his Systema Naturae in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect and classify animals, plants, and minerals, while publishing several volumes. He was one of the most acclaimed scientists in Europe at the time of his death.

Philosopher Jean-Jacques Rousseau sent him the message: "Tell him I know no greater man on earth." Johann Wolfgang von Goethe wrote: "With the exception of Shakespeare and Spinoza, I know no one among the no longer living who has influenced me more strongly." Swedish author August Strindberg wrote: "Linnaeus was in reality a poet who happened to become a naturalist." Linnaeus has been called Princeps botanicorum (Prince of Botanists) and "The Pliny of the North". He is also considered as one of the founders of modern ecology.

In botany and zoology, the abbreviation L. is used to indicate Linnaeus as the authority for a species' name. In older publications, the abbreviation "Linn." is found. Linnaeus's remains comprise the type specimen for the species Homo sapiens following the International Code of Zoological Nomenclature, since the sole specimen that he is known to have examined was himself.

1788 – South Carolina ratifies the United States Constitution as the eighth American state.

South Carolina (/ˌkærəˈlaɪnə/ (About this soundlisten)) is a state in the Southeastern region of the United States. It is bordered to the north by North Carolina, to the southeast by the Atlantic Ocean, and to the southwest by Georgia across the Savannah River. South Carolina is the 40th most extensive and 23rd most populous U.S. state. In 2019 its GDP was $213.45 billion. South Carolina is composed of 46 counties. The capital is Columbia with a population of 133,273 in 2019; while its largest city is Charleston with a 2019 population of 135,257. The Greenville–Anderson–Mauldin metropolitan area is the largest in the state, with a 2018 population estimate of 906,626.

South Carolina was named in honor of King Charles I of England, who first formed the English colony, with Carolus being Latin for "Charles". South Carolina became the eighth state to ratify the U.S. Constitution on May 23, 1788. It also became the first state to vote in favor of secession from the Union on December 20, 1860. After the American Civil War, it was readmitted into the United States on June 25, 1868.

1848 Born: Otto Lilienthal, German pilot and engineer (d. 1896)

Karl Wilhelm Otto Lilienthal (23 May 1848 – 10 August 1896) was a German pioneer of aviation who became known as the "flying man". He was the first person to make well-documented, repeated, successful flights with gliders. Newspapers and magazines published photographs of Lilienthal gliding, favorably influencing public and scientific opinion about the possibility of flying machines becoming practical. On 9 August 1896, his glider stalled and he was unable to regain control. Falling from about 15 m (50 ft), he broke his neck and died the next day.

Lilienthal's greatest contribution was in the development of heavier-than-air flight. He made his flights from an artificial hill he built near Berlin and from natural hills, especially in the Rhinow region.

The filing of a U.S. Patent in 1894 by Lilienthal directed pilots to grip the "bar" for carrying and flying the hang glider. The A-frame of Percy Pilcher and Lilienthal echoes in today's control frame for hang gliders and ultralight aircraft. Working in conjunction with his brother Gustav, Lilienthal made over 2,000 flights in gliders of his design starting in 1891 with his first glider version, the Derwitzer, until his death in a gliding crash in 1896. His total flying time was five hours.

At the beginning, in 1891, Lilienthal succeeded with jumps and flights covering a distance of about 25 meters (82 ft). He could use the updraft of a 10 m/s wind against a hill to remain stationary with respect to the ground, shouting to a photographer on the ground to maneuver into the best position for a photo. In 1893, in the Rhinow Hills, he was able to achieve flight distances as long as 250 meters (820 ft). This record remained unbeaten for him or anyone else at the time of his death.

Lilienthal did research in accurately describing the flight of birds, especially storks, and used polar diagrams for describing the aerodynamics of their wings. He made many experiments in an attempt to gather reliable aeronautical data.

Here are some events that happened on May 22nd. It could be an event or a person that died or was born on that day

1762 – Trevi Fountain is officially completed and inaugurated in Rome.

The Trevi Fountain (Italian: Fontana di Trevi) is a fountain in the Trevi district in Rome, Italy, designed by Italian architect Nicola Salvi and completed by Giuseppe Pannini and several others. Standing 26.3 metres (86 ft) high and 49.15 metres (161.3 ft) wide, it is the largest Baroque fountain in the city and one of the most famous fountains in the world.

The fountain has appeared in several notable films, including Roman Holiday (1953), the eponymous Three Coins in the Fountain (1954), Federico Fellini's La Dolce Vita (1960), and The Lizzie McGuire Movie (2003).

In 1629, Pope Urban VIII, finding the earlier fountain insufficiently dramatic, asked Gian Lorenzo Bernini to sketch possible renovations, but the project was abandoned when the pope died. Though Bernini's project was never constructed, there are many Bernini touches in the fountain as it exists today. An early, influential model by Pietro da Cortona, preserved in the Albertina, Vienna, also exists, as do various early 18th century sketches, most unsigned, as well as a project attributed to Nicola Michetti one attributed to Ferdinando Fuga and a French design by Edmé Bouchardon.

Competitions had become popular during the Baroque era to design buildings, fountains, as well as the Spanish Steps. In 1730, Pope Clement XII organized a contest in which Nicola Salvi initially lost to Alessandro Galilei – but due to the outcry in Rome over a Florentine having won, Salvi was awarded the commission anyway. Work began in 1732.

Salvi died in 1751 with his work half finished, but he had made sure a barber's unsightly sign would not spoil the ensemble, hiding it behind a sculpted vase, called by Romans the asso di coppe, the "Ace of Cups", because of its resemblance to a Tarot card. Four different sculptors were hired to complete the fountain's decorations: Pietro Bracci (whose statue of Oceanus sits in the central niche), Filippo della Valle, Giovanni Grossi, and Andrea Bergondi. Giuseppe Pannini was hired as architect.

The Trevi Fountain was finished in 1762 by Pannini, who substituted the present allegories for planned sculptures of Agrippa and Trivia, the Roman virgin. It was officially opened and inaugurated on 22 May by Pope Clement XIII.

The majority of the piece is made from Travertine stone, quarried near Tivoli, about 35 kilometres (22 miles) east of Rome.

1813 Born: Richard Wagner, German composer (d. 1883)

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

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

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

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

1906 – The Wright brothers are granted U.S. patent number 821,393 for their "Flying-Machine".

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

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

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

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

1907 Born: Hergé, Belgian author and illustrator (d. 1983)

Georges Prosper Remi (22 May 1907 – 3 March 1983), known by the pen name Hergé, was a Belgian cartoonist. He is best known for creating The Adventures of Tintin, the series of comic albums which are considered one of the most popular European comics of the 20th century. He was also responsible for two other well-known series, Quick & Flupke (1930–1940) and The Adventures of Jo, Zette and Jocko (1936–1957). His works were executed in his distinct ligne claire drawing style.

Born to a lower-middle-class family in Etterbeek, Brussels, Hergé began his career by contributing illustrations to Scouting magazines, developing his first comic series, The Adventures of Totor, for Le Boy-Scout Belge in 1926. Working for the conservative Catholic newspaper Le Vingtième Siècle, he created The Adventures of Tintin in 1929 on the advice of its editor Norbert Wallez. Revolving around the actions of boy reporter Tintin and his dog Snowy, the series' early installments — Tintin in the Land of the Soviets, Tintin in the Congo, and Tintin in America — were designed as conservative propaganda for children. Domestically successful, after serialisation the stories were published in book form, with Hergé continuing the series and also developing both the Quick & Flupke and Jo, Zette and Jocko series for Le Vingtième Siècle. Influenced by his friend Zhang Chongren, from 1934 Hergé placed far greater emphasis on conducting background research for his stories, resulting in increased realism from The Blue Lotus onward. Following the German occupation of Belgium in 1940, Le Vingtième Siècle was closed, but Hergé continued his series in Le Soir, a popular newspaper controlled by the Nazi administration.

After the Allied liberation of Belgium in 1944, Le Soir was shut down and its staff — including Hergé — accused of having been collaborators. An official investigation was launched, and while no charges were brought against Hergé, in subsequent years he repeatedly faced accusations of having been a traitor and collaborator. With Raymond Leblanc he established Tintin magazine in 1946, through which he serialised new Adventures of Tintin stories. As the magazine's artistic director, he also oversaw the publication of other successful comics series, such as Edgar P. Jacobs' Blake and Mortimer. In 1950 he established Studios Hergé as a team to aid him in his ongoing projects; prominent staff members Jacques Martin and Bob de Moor greatly contributed to subsequent volumes of The Adventures of Tintin. Amid personal turmoil following the collapse of his first marriage, he produced Tintin in Tibet, his personal favourite of his works. In later years he became less prolific, and unsuccessfully attempted to establish himself as an abstract artist.

Hergé's works have been widely acclaimed for their clarity of draughtsmanship and meticulous, well-researched plots. They have been the source of a wide range of adaptations, in theatre, radio, television, cinema, and computer gaming. He remains a strong influence on the comic book medium, particularly in Europe. He is widely celebrated in Belgium: a Hergé Museum was established in Louvain-la-Neuve in 2009.

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.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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