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

1616 Died: Miguel de Cervantes, Spanish novelist, poet, and playwright (b. 1547)

Miguel de Cervantes Saavedra (29 September 1547 (assumed) – 22 April 1616 ) was a Spanish writer widely regarded as the greatest writer in the Spanish language, and one of the world's pre-eminent novelists. He is best known for his novel Don Quixote, a work often cited as both the first modern novel, and one of the pinnacles of literature.

Much of his life was spent in poverty and obscurity, many of its details are disputed or unknown, and the bulk of his surviving work was produced in the three years preceding his death. Despite this, his influence and literary contribution are reflected by the fact Spanish is often referred to as "the language of Cervantes".

In 1569, Cervantes was forced to leave Spain and moved to Rome, where he worked in the household of a cardinal. In 1570, he enlisted in a Spanish Navy infantry regiment, and was badly wounded at the Battle of Lepanto in October 1571. He served as a soldier until 1575, when he was captured by Barbary pirates; after five years in captivity, he was ransomed, and returned to Madrid.

His first significant novel, titled La Galatea, was published in 1585, but he continued to work as a purchasing agent, then later a government tax collector. Part One of Don Quixote was published in 1605, Part Two in 1615. Other works include the 12 Novelas ejemplares (Exemplary Novels); a long poem, the Viaje del Parnaso (Journey to Parnassus); and Ocho comedias y ocho entremeses (Eight Plays and Eight Entr'actes). Los trabajos de Persiles y Sigismunda (The Travails of Persiles and Sigismunda), was published posthumously in 1616.

1854 Born: Henri La Fontaine, Belgian lawyer and author, Nobel Prize laureate (d. 1943)

Henri La Fontaine (22 April 1854 – 14 May 1943), was a Belgian international lawyer and president of the International Peace Bureau. He received the Nobel Prize for Peace in 1913 because " he was the effective leader of the peace movement in Europe".

La Fontaine was born in Brussels on 22 April 1854 and studied law at the Free University of Brussels (now split into the Université libre de Bruxelles and the Vrije Universiteit Brussel). He was admitted to the bar in 1877 and established a reputation as an authority on international law. He and his sister Léonie La Fontaine were early advocates for women's rights and suffrage, founding in 1890 the Belgian League for the Rights of Women. In 1893, he became professor of international law at the Free University of Brussels and two years later was elected to the Belgian Senate as a member of the Socialist Party. He served as vice chairman of the Senate from 1919 to 1932.

La Fontaine took an early interest in the International Peace Bureau, founded in 1882, and was influential in the Bureau's efforts to bring about The Hague Peace Conferences of 1899 and 1907. He served as president of the Bureau from 1907 until his death in 1943. World War I convinced La Fontaine that the world would establish an international court when peace returned. He proposed a number of possible members, including Joseph Hodges Choate, Elihu Root, Charles William Eliot, and Andrew Dickson White. La Fontaine also promoted the idea of unification of the world's pacifist organizations.

He was a member of the Belgian delegation to the Paris Peace Conference in 1919 and to the League of Nations Assembly (1920–21). In other efforts to foster world peace, he founded the Centre Intellectuel Mondial (later merged into the League of Nations Institute for Intellectual Co-operation) and proposed such organizations as a world school and university, and a world parliament. In 1907, with Paul Otlet, he founded the Union of International Associations. He also is the co-founder of Institut International de Bibliographie (which later became the International Federation for Information and Documentation, FID) along with Paul Otlet. It was in this role that he and Otlet attended the World Congress of Universal Documentation in 1937.

Henri La Fontaine was a freemason, and a member of the lodge Les Amis Philanthropes in Brussels. He died on 14 May 1943 in Brussels.

1870 Born: Vladimir Lenin, Russian revolutionary and founder of Soviet Russia (d. 1924)

Vladimir Ilyich Ulyanov (22 April 1870 – 21 January 1924), better known by his alias Lenin, was a Russian revolutionary, politician, and political theorist. He served as the head of government of Soviet Russia from 1917 to 1924 and of the Soviet Union from 1922 to 1924. Under his administration, Russia, and later the Soviet Union, became a one-party Marxist–Leninist state governed by the Communist Party of the Soviet Union. Ideologically a Marxist, he developed a variant of it known as Leninism.

Born to a moderately prosperous middle-class family in Simbirsk (now Ulyanovsk), Lenin embraced revolutionary socialist politics following his brother's 1887 execution. Expelled from Kazan Imperial University for participating in protests against the Russian Empire's Tsarist government, he devoted the following years to a law degree. He moved to Saint Petersburg in 1893 and became a senior Marxist activist. In 1897, he was arrested for sedition and exiled to Shushenskoye for three years, where he married Nadezhda Krupskaya. After his exile, he moved to Western Europe, where he became a prominent theorist in the Marxist Russian Social Democratic Labour Party (RSDLP). In 1903, he took a key role in the RSDLP ideological split, leading the Bolshevik faction against Julius Martov's Mensheviks. Following Russia's failed Revolution of 1905, he campaigned for the First World War to be transformed into a Europe-wide proletarian revolution, which as a Marxist he believed would cause the overthrow of capitalism and its replacement with socialism. After the 1917 February Revolution ousted the Tsar and established a Provisional Government, he returned to Russia to play a leading role in the October Revolution in which the Bolsheviks overthrew the new regime.

Lenin's Bolshevik government initially shared power with the Left Socialist Revolutionaries, elected soviets, and a multi-party Constituent Assembly, although by 1918 it had centralised power in the new Communist Party. Lenin's administration redistributed land among the peasantry and nationalised banks and large-scale industry. It withdrew from the First World War by signing a treaty conceding territory to the Central Powers, and promoted world revolution through the Communist International. Opponents were suppressed in the Red Terror, a violent campaign administered by the state security services; tens of thousands were killed or interned in concentration camps. His administration defeated right and left-wing anti-Bolshevik armies in the Russian Civil War from 1917 to 1922 and oversaw the Polish–Soviet War of 1919–1921. Responding to wartime devastation, famine, and popular uprisings, in 1921 Lenin encouraged economic growth through the market-oriented New Economic Policy. Several non-Russian nations had secured independence from the Russian Empire after 1917, but three were re-united into the new Soviet Union in 1922. His health failing, Lenin died in Gorki, with Joseph Stalin succeeding him as the pre-eminent figure in the Soviet government.

Widely considered one of the most significant and influential figures of the 20th century, Lenin was the posthumous subject of a pervasive personality cult within the Soviet Union until its dissolution in 1991. He became an ideological figurehead behind Marxism–Leninism and thus a prominent influence over the international communist movement. A controversial and highly divisive historical figure, Lenin is viewed by supporters as a champion of socialism and the working class, while critics on both the left and right emphasize his role as founder and leader of an authoritarian regime responsible for political repression and mass killings.

1933 Died: Henry Royce, English engineer and businessman, co-founded Rolls-Royce Limited (b. 1863)

Sir Frederick Henry Royce, 1st Baronet(27 March 1863 – 22 April 1933) was an English engineer famous for his designs of car and aeroplane engines with a reputation for reliability and longevity. With Charles Rolls (1877 – 1910) and Claude Johnson (1864 – 1926), he founded Rolls-Royce.

Rolls-Royce initially focused on large 40-50 horsepower motor cars, the Silver Ghost and its successors. Royce produced his first aero engine shortly after the outbreak of the First World War and aircraft engines became Rolls-Royce's principal product.

Royce's health broke down in 1911 and he was persuaded to leave his factory in the Midlands at Derby and, taking a team of designers, move to the south of England spending winters in the south of France. He died at his home in Sussex in the spring of 1933.

1984 Died: Ansel Adams, American photographer and environmentalist (b. 1902)

Ansel Easton Adams (February 20, 1902 – April 22, 1984) was an American landscape photographer and environmentalist known for his black-and-white images of the American West. He helped found Group f/64, an association of photographers advocating "pure" photography which favored sharp focus and the use of the full tonal range of a photograph. He and Fred Archer developed an exacting system of image-making called the Zone System, a method of achieving a desired final print through a deeply technical understanding of how tonal range is recorded and developed in exposure, negative development, and printing. The resulting clarity and depth of such images characterized his photography.

Adams was a life-long advocate for environmental conservation, and his photographic practice was deeply entwined with this advocacy. At age 12, he was given his first camera during his first visit to Yosemite National Park. He developed his early photographic work as a member of the Sierra Club. He was later contracted with the United States Department of the Interior to make photographs of national parks. For his work and his persistent advocacy, which helped expand the National Park system, he was awarded the Presidential Medal of Freedom in 1980.

Adams was a key advisor in establishing the photography department at the Museum of Modern Art in New York, an important landmark in securing photography's institutional legitimacy. He helped to stage that department's first photography exhibition, helped found the photography magazine Aperture, and co-founded the Center for Creative Photography at the University of Arizona.

1994 Died: Richard Nixon, American lieutenant, lawyer, and politician, 37th President of the United States (b. 1913)

Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th president of the United States, serving from 1969 to 1974. A member of the Republican Party, Nixon previously served as the 36th vice president from 1953 to 1961, having risen to national prominence as a representative and senator from California. After five years in the White House that saw the conclusion to the U.S. involvement in the Vietnam War, détente with the Soviet Union and China, and the establishment of the Environmental Protection Agency, he became the only president to resign from the office, following the Watergate scandal.

Nixon was born into a poor family of Quakers in a small town in Southern California. He graduated from Duke University School of Law in 1937 and returned to California to practice law. He and his wife Pat moved to Washington in 1942 to work for the federal government. He served on active duty in the Navy Reserve during World War II. He was elected to the House of Representatives in 1946. His pursuit of the Hiss Case established his reputation as a leading anti-Communist which elevated him to national prominence. In 1950, he was elected to the Senate. He was the running mate of Dwight D. Eisenhower, the Republican Party's presidential nominee in the 1952 election, subsequently serving for eight years as the vice president. He unsuccessfully ran for president in 1960, narrowly losing to John F. Kennedy. Nixon then lost a race for governor of California to Pat Brown in 1962. In 1968, he ran for the presidency again and was elected, defeating Hubert Humphrey and George Wallace in a close election.

Nixon ended American involvement in Vietnam in 1973, ending the military draft that same year. Nixon's visit to China in 1972 eventually led to diplomatic relations between the two nations, and he gained the Anti-Ballistic Missile Treaty with the Soviet Union the same year. His administration generally transferred power from federal control to state control. He imposed wage and price controls for 90 days, enforced desegregation of Southern schools, established the Environmental Protection Agency, and began the War on Cancer. He also presided over the Apollo 11 Moon landing, which signaled the end of the Space Race. He was re-elected in one of the largest electoral landslides in American history in 1972 when he defeated George McGovern.

In his second term, Nixon ordered an airlift to resupply Israeli losses in the Yom Kippur War, a war which led to the oil crisis at home. By late 1973, Watergate escalated, costing Nixon much of his political support. On August 9, 1974, facing almost certain impeachment and removal from office, he became the first American president to resign. Afterwards, he was issued a pardon by his successor, Gerald Ford. In 20 years of retirement, Nixon wrote his memoirs and nine other books and undertook many foreign trips, rehabilitating his image into that of an elder statesman and leading expert on foreign affairs. He suffered a debilitating stroke on April 18, 1994, and died four days later at age 81. Surveys of historians and political scientists have ranked Nixon as a below-average president. However, evaluations of him have proven complex, with successes as president contrasted against the circumstances of his departure from office.

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

1797 Born: Alfred de Vigny, French author, poet, and playwright (d. 1863)

Alfred Victor, Comte de Vigny (27 March 1797 – 17 September 1863) was a French poet and early leader of French Romanticism. He also produced novels, plays, and translations of Shakespeare.

He settled in Paris with his young English bride Lydia Bunbury, whom he married in Pau in 1825. He collected his recent works in January 1826 in Poèmes antiques et modernes. Three months later he published the first important historical novel in French, Cinq-Mars, based on the life of Louis XIII's favorite Henri Coiffier de Ruzé, Marquis of Cinq-Mars, who conspired against the Cardinal de Richelieu. With the success of these two volumes, Vigny seemed to be the rising star of the Romantic movement, though one of Vigny's best friends, Victor Hugo, soon usurped that role. Vigny wrote of Hugo: "The Victor I loved is no more... now he likes to make saucy remarks and is turning into a liberal, which does not suit him." Unlike Hugo and Alphonse de Lamartine, who moved gradually to the center and then to the left during the 1830s, Vigny remained pliantly centrist in his politics: he accepted the July monarchy, at first welcomed and then rejected the Second French Republic, and then supported Napoleon III. Vigny later denounced members of his inner circle whom he suspected of republican sympathies to the imperial police.

Although Vigny gained success as a writer, his personal life was not happy. His marriage was a disappointment; his relationship with Marie Dorval was plagued by jealousy; and his literary talent was eclipsed by the achievements of others. He grew embittered. After the death of his mother in 1838 he inherited the property of Maine-Giraud, near Angoulême, where it was said that he had withdrawn to his 'ivory tower' (an expression Sainte-Beuve coined with reference to Vigny). There Vigny wrote some of his most famous poems, including La Mort du loup and La Maison du berger. Proust regarded La Maison du berger as the greatest French poem of the 19th century. In 1845, after several unsuccessful attempts to be elected, Vigny became a member of the Académie française.

In later years, Vigny ceased to publish. He continued to write, however, and his Journal is considered by modern scholars to be a great work in its own right, though it awaits a definitive scholarly edition. Vigny considered himself a thinker as well as a literary author; he was, for example, one of the first French writers to take a serious interest in Buddhism. His own philosophy of life was pessimistic and stoical, but celebrated human fraternity, the growth of knowledge, and mutual assistanc as high values. He was the first in literary history to use the word spleen in the sense of woe, grief, gall, descriptive of the condition of the soul of modern man. In his later years he spent much time preparing the posthumous collection of poems now known as Les Destinées, for which his intended title was Poèmes philosophiques. It concludes with Vigny's final message to the world, L'Esprit pur.

1845 Born: Wilhelm Röntgen, German physicist and academic, Nobel Prize laureate (d. 1923)

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

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

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

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

1822 Born: Louis Pasteur, French chemist and microbiologist (d. 1895)

Louis Pasteur (December 27, 1822 – September 28, 1895) was a French biologist, microbiologist, and chemist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization. He is remembered for his remarkable breakthroughs in the causes and prevention of diseases, and his discoveries have saved many lives ever since. He reduced mortality from puerperal fever and created the first vaccines for rabies and anthrax.

His medical discoveries provided direct support for the germ theory of disease and its application in clinical medicine. He is best known to the general public for his invention of the technique of treating milk and wine to stop bacterial contamination, a process now called pasteurization. He is regarded as one of the three main founders of bacteriology, together with Ferdinand Cohn and Robert Koch, and is popularly known as the "father of microbiology".

Pasteur was responsible for disproving the doctrine of spontaneous generation. He performed experiments that showed that, without contamination, microorganisms could not develop. Under the auspices of the French Academy of Sciences, he demonstrated that in sterilized and sealed flasks, nothing ever developed; and, conversely, in sterilized but open flasks, microorganisms could grow. Although Pasteur was not the first to propose the germ theory, his experiments indicated its correctness and convinced most of Europe that it was true.

Today, he is often regarded as one of the fathers of germ theory. Pasteur made significant discoveries in chemistry, most notably on the molecular basis for the asymmetry of certain crystals and racemization. Early in his career, his investigation of tartaric acid resulted in the first resolution of what is now called optical isomers. His work led the way to the current understanding of a fundamental principle in the structure of organic compounds.

He was the director of the Pasteur Institute, established in 1887, until his death, and his body was interred in a vault beneath the institute. Although Pasteur made groundbreaking experiments, his reputation became associated with various controversies. Historical reassessment of his notebook revealed that he practiced deception to overcome his rivals

1831 – Charles Darwin embarks on his journey aboard HMS Beagle, during which he will begin to formulate his theory of evolution.

Charles Robert Darwin (12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process that he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history, and he was honoured by burial in Westminster Abbey.

Darwin published his theory of evolution with compelling evidence in his 1859 book On the Origin of Species. By the 1870s, the scientific community and a majority of the educated public had accepted evolution as a fact. However, many favoured competing explanations which gave only a minor role to natural selection, and it was not until the emergence of the modern evolutionary synthesis from the 1930s to the 1950s that a broad consensus developed in which natural selection was the basic mechanism of evolution. Darwin's scientific discovery is the unifying theory of the life sciences, explaining the diversity of life.

Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. Studies at the University of Cambridge (Christ's College) encouraged his passion for natural science. His five-year voyage on HMS Beagle established him as an eminent geologist whose observations and theories supported Charles Lyell's conception of gradual geological change, and publication of his journal of the voyage made him famous as a popular author.

Puzzled by the geographical distribution of wildlife and fossils he collected on the voyage, Darwin began detailed investigations, and in 1838 conceived his theory of natural selection. Although he discussed his ideas with several naturalists, he needed time for extensive research and his geological work had priority. He was writing up his theory in 1858 when Alfred Russel Wallace sent him an essay that described the same idea, prompting immediate joint publication of both of their theories. Darwin's work established evolutionary descent with modification as the dominant scientific explanation of diversification in nature. In 1871 he examined human evolution and sexual selection in The Descent of Man, and Selection in Relation to Sex, followed by The Expression of the Emotions in Man and Animals (1872). His research on plants was published in a series of books, and in his final book, The Formation of Vegetable Mould, through the Actions of Worms (1881), he examined earthworms and their effect on soil.

1901 Born: Marlene Dietrich, German-American actress and singer (d. 1992)

Marie Magdalene "Marlene" Dietrich (27 December 1901 – 6 May 1992) was a German-American actress and singer. Her career spanned from the 1910s to the 1980s.

In 1920s Berlin, Dietrich performed on the stage and in silent films. Her performance as Lola-Lola in The Blue Angel (1930), brought her international acclaim and a contract with Paramount Pictures. Dietrich starred in many Hollywood films such as Morocco (1930), Shanghai Express (1932) and Desire (1936). She successfully traded on her glamorous persona and "exotic" looks, and became one of the highest-paid actresses of the era. Throughout World War II, she was a high-profile entertainer in the United States. Although she still made occasional films after the war such as Witness for the Prosecution (1957), Dietrich spent most of the 1950s to the 1970s touring the world as a marquee live-show performer.

Dietrich was known for her humanitarian efforts during the war, housing German and French exiles, providing financial support and even advocating their American citizenship. For her work on improving morale on the front lines during the war, she received several honors from the United States, France, Belgium and Israel. In 1999, the American Film Institute named Dietrich the ninth greatest female screen legend of classic Hollywood cinema.

1923 Died: Gustave Eiffel, French architect and engineer, co-designed the Eiffel Tower (b. 1832)

Alexandre Gustave Eiffel (15 December 1832 – 27 December 1923) was a French civil engineer. A graduate of École Centrale Paris, he made his name building various bridges for the French railway network, most famously the Garabit viaduct. He is best known for the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, and his contribution to building the Statue of Liberty in New York.

In 1881 Eiffel was contacted by Auguste Bartholdi who was in need of an engineer to help him to realise the Statue of Liberty. Some work had already been carried out by Eugène Viollet-Le-Duc, but he had died in 1879. Eiffel was selected because of his experience with wind stresses. Eiffel devised a structure consisting of a four-legged pylon to support the copper sheeting which made up the body of the statue. The entire statue was erected at the Eiffel works in Paris before being dismantled and shipped to the United States.

After his retirement from engineering, Eiffel focused on research into meteorology and aerodynamics, making significant contributions in both fields.

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

1642 – Abel Tasman becomes the first European to discover the island Van Diemen's Land (later renamed Tasmania).

Abel Janszoon Tasman (1603 – 10 October 1659) was a Dutch seafarer, explorer, and merchant, best known for his voyages of 1642 and 1644 in the service of the Dutch East India Company (VOC). He was the first known European explorer to reach the islands of Van Diemen's Land (now Tasmania) and New Zealand, and to sight the Fiji islands.

Tasman's ten-month voyage in 1642–43 had significant consequences. By circumnavigating Australia (albeit at a distance) Tasman proved that the small fifth continent was not joined to any larger sixth continent, such as the long-imagined Southern Continent. Further, Tasman's suggestion that New Zealand was the western side of that Southern Continent was seized upon by many European cartographers who, for the next century, depicted New Zealand as the west coast of a Terra Australis rising gradually from the waters around Tierra del Fuego. This theory was eventually disproved when Captain Cook circumnavigated New Zealand in 1769.

1859 – Charles Darwin publishes On the Origin of Species.

Charles Robert Darwin (12 February 1809 – 19 April 1882) was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science.

1991 Died: Freddie Mercury, Tanzanian-English singer-songwriter, lead vocalist of Queen, and producer (b. 1946)

Freddie Mercury (born Farrokh Bulsara; 5 September 1946 – 24 November 1991) was a British singer, songwriter, record producer, and lead vocalist of the rock band Queen. Regarded as one of the greatest lead singers in the history of rock music, he was known for his flamboyant stage persona and four-octave vocal range. Mercury defied the conventions of a rock frontman, with his highly theatrical style influencing the artistic direction of Queen.

Born in 1946 in Zanzibar to Parsi-Indian parents, he attended English-style boarding schools in India from the age of eight and returned to Zanzibar after secondary school. In 1964, his family fled the Zanzibar Revolution, moving to Middlesex, England. Having studied and written music for years, he formed Queen in 1970 with guitarist Brian May and drummer Roger Taylor. Mercury wrote numerous hits for Queen, including "Killer Queen", "Bohemian Rhapsody", "Somebody to Love", "We Are the Champions", "Don't Stop Me Now", and "Crazy Little Thing Called Love". His charismatic stage performances often saw him interact with the audience, as displayed at the 1985 Live Aid concert. He also led a solo career and served as a producer and guest musician for other artists.

Mercury died in 1991 at age 45 due to complications from AIDS. He confirmed the day before his death that he had contracted the disease, having been diagnosed in 1987. Mercury had continued to record with Queen following his diagnosis, and he was posthumously featured on the band’s final album, Made in Heaven (1995).
