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


1832 Died: Georges Cuvier, French zoologist and academic (b. 1769)

Jean Léopold Nicolas Frédéric, Baron Cuvier (23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French naturalist and zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils.

Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his Essay on the Theory of the Earth (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophic flooding events. In this way, Cuvier became the most influential proponent of catastrophism in geology in the early 19th century. His study of the strata of the Paris basin with Alexandre Brongniart established the basic principles of biostratigraphy.

Among his other accomplishments, Cuvier established that elephant-like bones found in the USA belonged to an extinct animal he later would name as a mastodon, and that a large skeleton dug up in Paraguay was of Megatherium, a giant, prehistoric ground sloth. He named the pterosaur Pterodactylus, described (but did not discover or name) the aquatic reptile Mosasaurus, and was one of the first people to suggest the earth had been dominated by reptiles, rather than mammals, in prehistoric times.

His most famous work is Le Règne Animal (1817; English: The Animal Kingdom). In 1819, he was created a peer for life in honor of his scientific contributions. Thereafter, he was known as Baron Cuvier. He died in Paris during an epidemic of cholera. Some of Cuvier's most influential followers were Louis Agassiz on the continent and in the United States, and Richard Owen in Britain. His name is one of the 72 names inscribed on the Eiffel Tower.

1857 Born: Ronald Ross, Indian-English physician and mathematician, Nobel Prize laureate (d. 1932)

Sir Ronald Ross (13 May 1857 – 16 September 1932) was a British medical doctor who received the Nobel Prize for Physiology or Medicine in 1902 for his work on the transmission of malaria, becoming the first British Nobel laureate, and the first born outside Europe. His discovery of the malarial parasite in the gastrointestinal tract of a mosquito in 1897 proved that malaria was transmitted by mosquitoes, and laid the foundation for the method of combating the disease. He was a polymath, writing a number of poems, published several novels, and composed songs. He was also an amateur artist and natural mathematician. He worked in the Indian Medical Service for 25 years. It was during his service that he made the groundbreaking medical discovery. After resigning from his service in India, he joined the faculty of Liverpool School of Tropical Medicine, and continued as Professor and Chairman of Tropical Medicine of the institute for 10 years. In 1926 he became Director-in-Chief of the Ross Institute and Hospital for Tropical Diseases, which was established in honour of his works. He remained there until his death.

1909 – The first Giro d'Italia starts from Milan. Italian cyclist Luigi Ganna will be the winner.

The Giro d'Italia (English: Tour of Italy; also known as the Giro) is an annual multiple-stage bicycle race primarily held in Italy, while also starting in, or passing through, other countries. The first race was organized in 1909 to increase sales of the newspaper La Gazzetta dello Sport; and is still run by a subsidiary of that paper's owner. The race has been held annually since its first edition in 1909, except during the two world wars and the 2020 coronavirus pandemic. As the Giro gained prominence and popularity the race was lengthened, and the peloton expanded from primarily Italian participation to riders from all over the world. The Giro is a UCI World Tour event, which means that the teams that compete in the race are mostly UCI WorldTeams, with some additional teams invited as 'wild cards'.

Along with the Tour de France and Vuelta a España, the Giro is one of cycling's prestigious three-week-long Grand Tours. The Giro is usually held during May, sometimes continuing into early June. While the route changes each year, the format of the race stays the same, with at least two time trials, and a passage through the mountains of the Alps, including the Dolomites. Like the other Grand Tours, the modern editions of the Giro d'Italia normally consist of 21 stages over a 23 or 24 day period that includes two or three rest days.

The rider with the lowest aggregate time is the leader of the general classification and wears the pink jersey. While the general classification gathers the most attention, stages wins are prestigious of themselves, and there are other contests held within the Giro: the points classification, the mountains classification for the climbers, young rider classification for the riders under the age of 25, and the team classification.

Here are some events that happened on March 14th. It could be an event or a person that died or was born on that day

1804 – Johann Strauss I, Austrian composer and conductor (d. 1849)

Johann Strauss I (March 14, 1804 – September 25, 1849) was an Austrian Romantic composer. He was famous for his waltzes, and he popularized them alongside Joseph Lanner, thereby setting the foundations for his sons to carry on his musical dynasty. He is perhaps best known for his composition of the Radetzky March (named after Joseph Radetzky von Radetz).

Strauss became deputy conductor of the orchestra to assist Lanner in commissions after it became so popular during the Fasching of 1824 and Strauss was soon placed in command of a second smaller orchestra which was formed as a result of the success of the parent orchestra. In 1825, he decided to form his own band and began to write music (chiefly, dance music) for it to play after he realized that he could also possibly emulate the success of Lanner in addition to putting an end to his financial struggles. By so doing, he would have made Lanner a serious rival although the rivalry did not entail hostile consequences as the musical competition was very productive for the development of the waltz as well as other dance music in Vienna.

He soon became one of the best-known and well loved dance composers in Vienna. During the carnival of 1826, Strauss inaugurated his long line of triumphs by introducing his band to the public of Vienna at the Schwan in the suburb of Roßau where his Täuberln-Walzer (Op. 1) at once established his reputation. He toured with his band to Germany, the Netherlands, Belgium and Britain. The conducting reins and management of this Strauss Orchestra would eventually be passed on to the hands of his sons until its disbandment by Eduard Strauss in 1901.

On a trip to France in 1837 he heard the quadrille and began to compose them himself, becoming largely responsible for introducing that dance to Austria in the 1840 Fasching, where it became very popular. It was this very trip (in 1837) which has proved Strauss' popularity with audiences from different social backgrounds and this paved the way to forming an ambitious plan to perform his music in England for the coronation of Queen Victoria in 1838. Strauss also adapted various popular melodies of his day into his works so as to ensure a wider audience, as evidenced in the incorporation of the Oberon overture into his early waltz, "Wiener Carneval", Op. 3, and also the French national anthem "La Marseillaise" into his "Paris-Walzer", Op. 101.

1820 Born: Victor Emmanuel II of Italy (d. 1878)

Victor Emmanuel II (14 March 1820 – 9 January 1878) was King of Sardinia from 1849 until 17 March 1861, when he assumed the title of King of Italy and became the first king of a united Italy since the 6th century, a title he held until his death in 1878. Borrowing from the old Latin title Pater Patriae of the Roman emperors, the Italians gave him the epithet of Father of the Fatherland (Italian: Padre della Patria).

Born in Turin as the eldest son of Charles Albert, Prince of Carignano, and Maria Theresa of Austria, he fought in the First Italian War of Independence (1848-49) before being made King of Piedmont-Sardinia following his father's abdication. He appointed Camillo Benso, Count of Cavour, as his Prime Minister, and he consolidated his position by suppressing the republican left. In 1855, he sent an expeditionary corps to side with French and British forces during the Crimean War; the deployment of Italian troops to the Crimea, and the gallantry shown by them in the Battle of the Chernaya (16 August 1855) and in the siege of Sevastopol led the Kingdom of Sardinia to be among the participants at the peace conference at the end of the war, where it could address the issue of the Italian unification to other European powers. This allowed Victor Emmanuel to ally himself with Napoleon III, Emperor of France. France had supported Sardinia in the Second Italian War of Independence, resulting in liberating Lombardy from Austrian rule.

Victor Emmanuel supported the Expedition of the Thousand (1860–1861) led by Giuseppe Garibaldi, which resulted in the rapid fall of the Kingdom of the Two Sicilies in southern Italy. However, Victor Emmanuel halted Garibaldi when he appeared ready to attack Rome, still under the Papal States, as it was under French protection. In 1860, Tuscany, Modena, Parma and Romagna decided to side with Sardinia-Piedmont, and Victor Emmanuel then marched victoriously in the Marche and Umbria after the victorious battle of Castelfidardo over the Papal forces. He subsequently met Garibaldi at Teano, receiving from him the control of southern Italy and becoming the first King of Italy on 17 March 1861.

In 1866, the Third Italian War of Independence allowed Italy to annex Veneto. In 1870, Victor Emmanuel also took advantage of the Prussian victory over France in the Franco-Prussian War to taking over the Papal States after the French withdrew. He entered Rome on 20 September 1870 and set up the new capital there on 2 July 1871. He died in Rome in 1878, and was buried in the Pantheon.

The Italian national monument Altare della Patria (or Vittoriano) in Rome was built in his honor.

1844 Born: Umberto I of Italy (d. 1900)

Umberto I (14 March 1844 – 29 July 1900), nicknamed the Good (Italian: il Buono), was the King of Italy from 9 January 1878 until his assassination on 29 July 1900.
Umberto's reign saw Italy attempt colonial expansion into the Horn of Africa, successfully gaining Eritrea and Somalia despite being defeated by Abyssinia at the Battle of Adwa in 1896. In 1882, he approved the Triple Alliance with the German Empire and Austria-Hungary.

He was deeply loathed in leftist circles because of his conservatism and support of the Bava-Beccaris massacre in Milan. He was especially hated by anarchists, who attempted to assassinate him during the first year of his reign. He was killed by another anarchist, Gaetano Bresci, two years after the Bava-Beccaris massacre.

1854 Born: Paul Ehrlich, German physician and academic, Nobel Prize laureate (d. 1915)

Paul Ehrlich (14 March 1854 – 20 August 1915) was a Nobel prize-winning German physician and scientist who worked in the fields of hematology, immunology, and antimicrobial chemotherapy. He is credited with finding a cure for syphilis in 1909. He invented the precursor technique to Gram staining bacteria. The methods he developed for staining tissue made it possible to distinguish between different types of blood cells, which led to the capability to diagnose numerous blood diseases.

His laboratory discovered arsphenamine (Salvarsan), the first effective medicinal treatment for syphilis, thereby initiating and also naming the concept of chemotherapy. Ehrlich popularized the concept of a magic bullet. He also made a decisive contribution to the development of an antiserum to combat diphtheria and conceived a method for standardizing therapeutic serums. 

In 1908, he received the Nobel Prize in Physiology or Medicine for his contributions to immunology. He was the founder and first director of what is now known as the Paul Ehrlich Institute.

1879 Born: Albert Einstein, German-American physicist, engineer, and academic, Nobel Prize laureate (d. 1955)

Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics). His work is also known for its influence on the philosophy of science. He is best known to the general public for his mass–energy equivalence formula E = mc2, which has been dubbed "the world's most famous equation". He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory.

The son of a salesman who later operated an electrochemical factory, Einstein was born in the German Empire but moved to Switzerland in 1895 and renounced his German citizenship in 1896. Specializing in physics and mathematics, he received his academic teaching diploma from the Swiss Federal Polytechnic School (German: eidgenössische polytechnische Schule) in Zürich in 1900. The following year, he acquired Swiss citizenship, which he kept for his entire life. After initially struggling to find work, from 1902 to 1909 he was employed as a patent examiner at the Swiss Patent Office in Bern.

Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led him to develop his special theory of relativity during his time at the Swiss Patent Office. In 1905, called his annus mirabilis (miracle year), he published four groundbreaking papers, which attracted the attention of the academic world; the first outlined the theory of the photoelectric effect, the second paper explained Brownian motion, the third paper introduced special relativity, and the fourth mass-energy equivalence. That year, at the age of 26, he was awarded a PhD by the University of Zurich.

Although initially treated with skepticism from many in the scientific community, Einstein's works gradually came to be recognised as significant advancements. He was invited to teach theoretical physics at the University of Bern in 1908 and the following year moved to the University of Zurich, then in 1911 to Charles University in Prague before returning to ETH (the newly renamed Federal Polytechnic School) in Zürich in 1912. In 1914, he was elected to the Prussian Academy of Sciences in Berlin, where he remained for 19 years. Soon after publishing his work on special relativity, Einstein began working to extend the theory to gravitational fields; he then published a paper on general relativity in 1916, introducing his theory of gravitation. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated the thermal properties of light and the quantum theory of radiation, the basis of the laser, which laid the foundation of the photon theory of light. In 1917, he applied the general theory of relativity to model the structure of the universe.

In 1933, while Einstein was visiting the United States, Adolf Hitler came to power. Because of his Jewish background, Einstein did not return to Germany. He settled in the United States and became an American citizen in 1940. On the eve of World War II, he endorsed a letter to President Franklin D. Roosevelt alerting FDR to the potential development of "extremely powerful bombs of a new type" and recommending that the US begin similar research. This eventually led to the Manhattan Project. Einstein supported the Allies, but he generally denounced the idea of using nuclear fission as a weapon. He signed the Russell–Einstein Manifesto with British philosopher Bertrand Russell, which highlighted the danger of nuclear weapons. He was affiliated with the Institute for Advanced Study in Princeton, New Jersey, until his death in 1955.

He published more than 300 scientific papers and more than 150 non-scientific works. His intellectual achievements and originality have made the word "Einstein" synonymous with "genius". Eugene Wigner compared him to his contemporaries, writing that "Einstein's understanding was deeper even than Jancsi von Neumann's. His mind was both more penetrating and more original".

1883 Died: Karl Marx, German philosopher, sociologist, and journalist (b. 1818)

Karl Heinrich Marx (5 May 1818 – 14 March 1883) was a German philosopher, economist, historian, sociologist, political theorist, journalist and socialist revolutionary.

Born in Trier, Germany, Marx studied law and philosophy at university. He married Jenny von Westphalen in 1843. Due to his political publications, Marx became stateless and lived in exile with his wife and children in London for decades, where he continued to develop his thought in collaboration with German thinker Friedrich Engels and publish his writings, researching in the reading room of the British Museum. His best-known titles are the 1848 pamphlet, The Communist Manifesto, and the three-volume Das Kapital. His political and philosophical thought had enormous influence on subsequent intellectual, economic and political history, and his name has been used as an adjective, a noun and a school of social theory.

Marx's critical theories about society, economics and politics – collectively understood as Marxism – hold that human societies develop through class struggle. In capitalism, this manifests itself in the conflict between the ruling classes (known as the bourgeoisie) that control the means of production and the working classes (known as the proletariat) that enable these means by selling their labour power in return for wages. Employing a critical approach known as historical materialism, Marx predicted that, like previous socio-economic systems, capitalism produced internal tensions which would lead to its self-destruction and replacement by a new system known as socialism.

For Marx, class antagonisms under capitalism, owing in part to its instability and crisis-prone nature, would eventuate the working class' development of class consciousness, leading to their conquest of political power and eventually the establishment of a classless, communist society constituted by a free association of producers. Marx actively pressed for its implementation, arguing that the working class should carry out organised revolutionary action to topple capitalism and bring about socio-economic emancipation.

Marx has been described as one of the most influential figures in human history, and his work has been both lauded and criticised. His work in economics laid the basis for much of the current understanding of labour and its relation to capital, and subsequent economic thought. Many intellectuals, labour unions, artists and political parties worldwide have been influenced by Marx's work, with many modifying or adapting his ideas. Marx is typically cited as one of the principal architects of modern social science.

1920 – About 80 % of the population in Zone II votes to remain part of Weimar Germany in the 1920 Schleswig plebiscites

The Schleswig plebiscites were two plebiscites, organized according to section XII, articles 100 to 115 of the Treaty of Versailles of 28 June 1919, in order to determine the future border between Denmark and Germany through the former duchy of Schleswig. The process was monitored by a commission with representatives from France, the United Kingdom, Norway and Sweden.

The plebiscites were held on 10 February and 14 March 1920, and the result was that the larger northern portion (Zone I) voted to join Denmark, while the smaller southern portion (Zone II) voted to remain part of Germany.

Here are some events that happened on February 8th. It could be an event or a person that died or was born on that day


1591 Born:  Guercino, Italian painter (d. 1666)

Giovanni Francesco Barbieri (February 8, 1591 – December 22, 1666), better known as Guercino, or il Guercino, was an Italian Baroque painter and draftsman from Cento in the Emilia region, who was active in Rome and Bologna. The vigorous naturalism of his early manner contrasts with the classical equilibrium of his later works. His many drawings are noted for their luminosity and lively style.

Guercino was remarkable for the extreme rapidity of his executions: he completed no fewer than 106 large altarpieces for churches, and his other paintings amount to about 144. He was also a prolific draftsman. His production includes many drawings, usually in ink, washed ink, or red chalk. Most of them were made as preparatory studies for his paintings, but he also drew landscapes, genre subjects, and caricatures for his own enjoyment. Guercino's drawings are known for their fluent style in which "rapid, calligraphic pen strokes combined with dots, dashes, and parallel hatching lines describe the forms". Guercino continued to paint and teach until his death in 1666, amassing a notable fortune. As he never married, his estate passed to his nephews and pupils, Benedetto Gennari II and Cesare Gennari.

1725 Died: Peter the Great, Russian emperor (b. 1672)

Peter the Great (Peter I or Peter Alexeyevich 9 June 1672 – 8 February 1725) ruled the Tsardom of Russia and later the Russian Empire from 7 May 1682 until his death in 1725, jointly ruling before 1696 with his elder half-brother, Ivan V. Through a number of successful wars, he expanded the Tsardom into a much larger empire that became a major European power and also laid the groundwork for the Russian navy after capturing ports at Azov and the Baltic Sea. He led a cultural revolution that replaced some of the traditionalist and medieval social and political systems with ones that were modern, scientific, Westernised and based on the Enlightenment. Peter's reforms had a lasting impact on Russia, and many institutions of the Russian government trace their origins to his reign. He is also known for founding and developing the city of Saint Petersburg, which remained the capital of Russia until 1917.

1820 Born: William Tecumseh Sherman, American general (d. 1891)

William Tecumseh Sherman (February 8, 1820 – February 14, 1891) was an American soldier, businessman, educator, and author. He served as a general in the Union Army during the American Civil War (1861–1865), receiving recognition for his command of military strategy as well as criticism for the harshness of the scorched earth policies he implemented in conducting total war against the Confederate States. British military theorist and historian B. H. Liddell Hart declared that Sherman was "the first modern general".

Born in Ohio to a politically prominent family, Sherman graduated in 1840 from the United States Military Academy at West Point. He interrupted his military career in 1853 to pursue private business ventures, and at the outbreak of the Civil War he was superintendent of the Louisiana State Seminary of Learning & Military Academy (now Louisiana State University). Sherman distinguished himself at the First Battle of Bull Run in 1861, before being transferred to the Western Theater. Stationed in Kentucky, his pessimism about the outlook of the war led to a nervous breakdown that required him to be briefly put on leave. He recovered by forging a close partnership with General Ulysses S. Grant. Sherman served under Grant in 1862 and 1863 during the battles of forts Henry and Donelson, the Battle of Shiloh, the campaigns that led to the fall of the Confederate stronghold of Vicksburg on the Mississippi River, as well as the Chattanooga Campaign that culminated with the routing of the Confederate armies in the state of Tennessee.

In 1864, Sherman succeeded Grant as the Union commander in the Western Theater. Sherman then led the capture of the strategic city of Atlanta, a military success that contributed to the re-election of President Abraham Lincoln. Sherman's subsequent march through Georgia and the Carolinas involved little fighting but large-scale destruction of cotton plantations and other infrastructure, a systematic policy intended to undermine the ability and willingness of the Confederacy to continue fighting. Sherman accepted the surrender of all the Confederate armies in the Carolinas, Georgia, and Florida in April 1865, but the terms that he negotiated were considered too lenient by US Secretary of War Edwin Stanton, who ordered General Grant to modify them.

When Grant became president of the United States in March 1869, Sherman succeeded him as Commanding General of the Army. Sherman served in that capacity from 1869 until 1883 and was responsible for the U.S. Army's engagement in the Indian Wars during that period. He steadfastly refused to be drawn into politics and in 1875 published his Memoirs, one of the best-known first-hand accounts of the Civil War.

1828 Born: Jules Verne, French author, poet, and playwright (d. 1905)

Jules Gabriel Verne (8 February 1828 – 24 March 1905) was a French novelist, poet, and playwright.

Verne's collaboration with the publisher Pierre-Jules Hetzel led to the creation of the Voyages extraordinaires, a widely popular series of scrupulously researched adventure novels including Journey to the Center of the Earth (1864), Twenty Thousand Leagues Under the Sea (1870), and Around the World in Eighty Days (1873).

Verne is generally considered a major literary author in France and most of Europe, where he has had a wide influence on the literary avant-garde and on surrealism. His reputation was markedly different in Anglophone regions where he had often been labeled a writer of genre fiction or children's books, largely because of the highly abridged and altered translations in which his novels have often been printed (until the 1980s, when his "literary reputation ... began to improve").

Verne has been the second most-translated author in the world since 1979, ranking between Agatha Christie and William Shakespeare. He has sometimes been called the "Father of Science Fiction", a title that has also been given to H. G. Wells, Mary Shelley, and Hugo Gernsback.

Here are some events that happened on January 14th. It could be an event or a person that died or was born on that day


1742 Died: Edmond Halley, English astronomer, geophysicist, mathematician, meteorologist, and physicist (b. 1656)

Edmond (or Edmund) Halley (8 November [O.S. 29 October] 1656 – 25 January 1742 [O.S. 14 January 1741]) was an English astronomer, geophysicist, mathematician, meteorologist, and physicist. He was the second Astronomer Royal in Britain, succeeding John Flamsteed in 1720.

From an observatory he constructed on Saint Helena, Halley recorded a transit of Mercury across the Sun. He realised a similar transit of Venus could be used to determine the size of the Solar System. He also used his observations to expand contemporary star maps. He aided in observationally proving Isaac Newton's laws of motion, and funded the publication of Newton's influential Philosophiæ Naturalis Principia Mathematica. From his September 1682 observations, he used the laws of motion to compute the periodicity of Halley's Comet in his 1705 Synopsis of the Astronomy of Comets. It was named after him upon its predicted return in 1758, which he did not live to see.

Beginning in 1698, he made sailing expeditions and made observations on the conditions of terrestrial magnetism. In 1718, he discovered the proper motion of the "fixed" stars

1874 Died:  Johann Philipp Reis, German physicist and academic, invented the Reis telephone (b. 1834)

Johann Philipp Reis (January 7, 1834 – January 14, 1874) was a self-taught German scientist and inventor. In 1861, he constructed the first make-and-break telephone, today called the Reis telephone.

In 1878, four years after his death and two years after Bell received his first telephone patent, European scientists dedicated a monument to Philip Reis as the inventor of the telephone.

Documents of 1947 in London's Science Museum later showed that after their technical adjustments, engineers from the British firm Standard Telephones and Cables (STC) found Reis' telephone dating from 1863 could transmit and "reproduce speech of good quality, but of low efficiency".

Sir Frank Gill, then chairman of STC, ordered the tests to be kept secret, as STC was then negotiating with AT&T, which had evolved from the Bell Telephone Company, created by Alexander Graham Bell. Professor Bell was generally accepted as having invented the telephone and Gill thought that evidence to the contrary might disrupt the ongoing negotiations.

1875 Born: Albert Schweitzer, French-Gabonese physician and philosopher, Nobel Prize laureate (d. 1965)

Albert Schweitzer (14 January 1875 – 4 September 1965) was an Alsatian polymath. He was a theologian, organist, writer, humanitarian, philosopher, and physician. A Lutheran, Schweitzer challenged both the secular view of Jesus as depicted by the historical-critical method current at this time, as well as the traditional Christian view. His contributions to the interpretation of Pauline Christianity concern the role of Paul's mysticism of "being in Christ" as primary and the doctrine of Justification by Faith as secondary.

He received the 1952 Nobel Peace Prize for his philosophy of "Reverence for Life", becoming the eighth Frenchman to be awarded that prize. His philosophy was expressed in many ways, but most famously in founding and sustaining the Albert Schweitzer Hospital in Lambaréné, in the part of French Equatorial Africa which is now Gabon. As a music scholar and organist, he studied the music of German composer Johann Sebastian Bach and influenced the Organ Reform Movement (Orgelbewegung).

1953 – Josip Broz Tito is inaugurated as the first President of Yugoslavia.

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

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

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

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

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

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

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

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

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

1957 Died: Humphrey Bogart, American actor (b. 1899)

Humphrey DeForest Bogart (December 25, 1899 – January 14, 1957) was an American film and stage actor. His performances in Classical Hollywood cinema films made him an American cultural icon. In 1999, the American Film Institute selected Bogart as the greatest male star of classic American cinema.

Bogart began acting in Broadway shows, beginning his career in motion pictures with Up the River (1930) for Fox. Bogart appeared in supporting roles for the next decade, sometimes portraying gangsters. Bogart was praised for his work as Duke Mantee in The Petrified Forest (1936), but remained secondary to other actors Warner Bros. cast in lead roles.

His breakthrough from supporting roles to stardom came with High Sierra (1941) and The Maltese Falcon (1941), considered one of the first great noir films. Bogart's private detectives, Sam Spade (in The Maltese Falcon) and Phillip Marlowe (in 1946's The Big Sleep), became the models for detectives in other noir films. His most significant romantic lead role was with Ingrid Bergman in Casablanca (1942), which earned him his first nomination for the Academy Award for Best Actor. Bogart and 19-year-old Lauren Bacall fell in love when they filmed To Have and Have Not (1944); soon after the main filming for The Big Sleep (1946, their second film together), he filed for divorce from his third wife and married Bacall. After their marriage, she played his love interest in Dark Passage (1947) and Key Largo (1948).

Bogart's performances in The Treasure of the Sierra Madre (1948) and In a Lonely Place (1950) are now considered among his best, although they were not recognized as such when the films were released. He reprised those unsettled, unstable characters as a World War II naval-vessel commander in The Caine Mutiny (1954), which was a critical and commercial hit and earned him another Best Actor nomination. As a cantankerous river steam launch skipper with Katharine Hepburn's missionary in the World War I adventure The African Queen (1951), Bogart received the Academy Award for Best Actor. In his later years, significant roles included The Barefoot Contessa with Ava Gardner and his on-screen competition with William Holden for Audrey Hepburn in Sabrina (1954). A heavy smoker and drinker, Bogart died from esophageal cancer in January 1957.

1972 – Queen Margrethe II of Denmark ascends the throne, the first Queen of Denmark since 1412 and the first Danish monarch not named Frederick or Christian since 1513.

Margrethe II (Danish: Margrethe 2; Greenlandic: Margrethe II; Faroese: Margreta 2.; full name: Margrethe Alexandrine Þórhildur Ingrid; born 16 April 1940) is the Queen of Denmark, as well as the supreme authority of the Church of Denmark and Commander-in-Chief of the Danish Defence. Born into the House of Glücksburg, a royal house with origins in Northern Germany, she was the eldest child of Frederick IX of Denmark and Ingrid of Sweden. She became heir presumptive to her father in 1953, when a constitutional amendment allowed women to inherit the throne.

Margrethe succeeded her father upon his death on 14 January 1972. On her accession, she became the first female monarch of Denmark since Margrethe I, ruler of the Scandinavian kingdoms in 1375–1412 during the Kalmar Union. In 1967, she married Henri de Laborde de Monpezat, with whom she has two sons: Crown Prince Frederik and Prince Joachim. She has been on the Danish throne for 47 years, becoming the second-longest-reigning Danish monarch after her ancestor Christian IV.

1972 Died: Frederick IX of Denmark (b. 1899)

Frederick IX (Christian Frederik Franz Michael Carl Valdemar Georg; 11 March 1899 – 14 January 1972) was King of Denmark from 1947 to 1972.

Born into the House of Glücksburg, Frederick was the elder son of King Christian X and Queen Alexandrine of Denmark. He became crown prince when his father succeeded as king in 1912. As a young man, he was educated at the Royal Danish Naval Academy. In 1935, he was married to Princess Ingrid of Sweden and they had three daughters, Margrethe, Benedikte and Anne-Marie. During Nazi Germany's occupation of Denmark, Frederick acted as regent on behalf of his father from 1942 until 1943.

Frederick became king on his father's death in early 1947. During Frederick IX's reign Danish society changed rapidly, the welfare state was expanded and, as a consequence of the booming economy of the 1960s, women entered the labour market. The modernization brought new demands on the monarchy and Frederick's role as a constitutional monarch. Frederick IX died in 1972, and was succeeded by his eldest daughter, Margrethe II.
