Here are some events that happened on April 25th. It could be an event or a person that died or was born on that day

1792 – "La Marseillaise" (the French national anthem) is composed by Claude Joseph Rouget de Lisle.

"La Marseillaise" is the national anthem of France. The song was written in 1792 by Claude Joseph Rouget de Lisle in Strasbourg after the declaration of war by France against Austria, and was originally titled "Chant de guerre pour l'Armée du Rhin" ("War Song for the Army of the Rhine").

The French National Convention adopted it as the Republic's anthem in 1795. The song acquired its nickname after being sung in Paris by volunteers from Marseille marching to the capital. The song is the first example of the "European march" anthemic style. The anthem's evocative melody and lyrics have led to its widespread use as a song of revolution and its incorporation into many pieces of classical and popular music.

Claude Joseph Rouget de Lisle (10 May 1760 – 26 June 1836), was a French army officer of the French Revolutionary Wars. He is known for writing the words and music of the Chant de guerre pour l'armée du Rhin in 1792, which would later be known as La Marseillaise and become the French national anthem.

The song that has immortalized him, "La Marseillaise", was composed at Strasbourg, where Rouget de Lisle was garrisoned in April 1792. France had just declared war on Austria, and the mayor of Strasbourg, baron Philippe-Frédéric de Dietrich, held a dinner for the officers of the garrison, at which he lamented that France had no national anthem. Rouget de Lisle returned to his quarters and wrote the words in a fit of patriotic excitement. The piece was at first called Chant de guerre pour l'armée du Rhin ("War Song for the Army of the Rhine") and only received its name of Marseillaise from its adoption by the Provençal volunteers whom Barbaroux introduced into Paris and who were prominent in the storming of the Tuileries Palace on 10 August 1792

Rouget de Lisle died in poverty in Choisy-le-Roi, Val de Marne. His ashes were transferred from Choisy-le-Roi cemetery to the Invalides on 14 July 1915, during World War I.

1874 Born: Guglielmo Marconi, Italian businessman and inventor, developed Marconi's law, Nobel Prize laureate (d. 1937)

Guglielmo Marconi, 1st Marquis of Marconi (25 April 1874 – 20 July 1937) was an Italian inventor and electrical engineer, known for his pioneering work on long-distance radio transmission,[5] development of Marconi's law, and a radio telegraph system. He is credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".

Marconi was also an entrepreneur, businessman, and founder of The Wireless Telegraph & Signal Company in the United Kingdom in 1897 (which became the Marconi Company). He succeeded in making an engineering and commercial success of radio by innovating and building on the work of previous experimenters and physicists. In 1929, Marconi was ennobled as a Marchese (marquis) by King Victor Emmanuel III of Italy, and, in 1931, he set up the Vatican Radio for Pope Pius XI.

1892 Died: Henri Duveyrier, French explorer (b. 1840)

Henri Duveyrier (28 February 1840, in Paris – 25 April 1892, in Sèvres), was a French explorer and geographer, most well known for his exploration of the Sahara.

Duveyrier was born in Paris, the eldest child of Charles Duveyrier (1803–1866), a well-known dramatist, and his English wife Ellen Claire née Denie. Charles Duveyrier was a follower of the utopian philosophical movement started by Henri de Saint-Simon. In 1857 and 1858, Duveyrier spent some months in London, where he met Heinrich Barth, then preparing an account of his travels in the western Sudan

Duveyrier was Auguste Warnier's guest in 1857 at his home in Kandouri, a suburb of Algiers, where he met Oscar MacCarthy. On 8 March 1857 Duveyrier and MacCarthy left on a five-week trip to Laghouat and back. Duveyrier was fascinated by the Tuaregs he met on this trip and the next year gave an account of Tuareg customs to the Berlin Oriental Society. Later Duveyrier made an unsuccessful attempt to reach Tuat, which was stopped by the Tuaregs at El Goléa. Duveyrier left in May 1859 and after an exhausting journey returned to Warnier's house on 5 December 1861, emaciated and delirious with fever. In 1864, two years after returning to France, he published Exploration du Sahara: les Touareg du nord (Exploration of the Sahara: Tuaregs of the North), for which he received the gold medal of the Paris Geographical Society.

In the Franco-Prussian War of 1870 he was taken prisoner by the Germans. After his release he made several further journeys in the Sahara, adding considerably to the knowledge of the regions immediately south of the Atlas Mountains, from the eastern confines of Morocco to Tunisia. He also examined the Algerian and Tunisian chotts and explored the interior of western Tripoli. Duveyrier devoted special attention to the customs and speech of the Tuareg people, with whom he lived for months at a time, and to the organization of the Senussi.

In 1881 he published La Tunisie, and in 1884 La confrérie musulmane de Sîdî Mohammed ben Alî-Senoûsi et son domaine géographique en l'année 1300 de l'Hégire.

Duveyrier was adversely affected by the tragedy that befell the Flatters Expedition of 1880-1 which put an end to the proposed Trans Sahara railway and military expansion in the region. Those who had dreamed of transforming the Tuareg into linemen for camel railway crossings blamed Duveyrier for their disappointment. Duveyrier's only error was in having described the Tuareg as veiled, turbaned medieval paladins; but the explorer was already shaken by the premature death of his fiancée, and embittered by the controversy, he committed suicide in 1892.

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

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

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

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

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

Daniel Defoe (born Daniel Foe; c. 1660 – 24 April 1731) was an English trader, writer, journalist, pamphleteer and spy. He is most famous for his novel Robinson Crusoe, published in 1719, which is claimed to be second only to the Bible in its number of translations. He has been seen as one of the earliest proponents of the English novel, and helped to popularize the form in Britain with others such as Aphra Behn and Samuel Richardson. Defoe wrote many political tracts and was often in trouble with the authorities, and spent a period in prison. Intellectuals and political leaders paid attention to his fresh ideas and sometimes consulted with him.

Defoe was a prolific and versatile writer, producing more than three hundred works—books, pamphlets, and journals—on diverse topics, including politics, crime, religion, marriage, psychology, and the supernatural. He was also a pioneer of business journalism and economic journalism.

1953 – Winston Churchill is knighted by Queen Elizabeth II.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Here are some events that happened on April 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 April 21st. It could be an event or a person that died or was born on that day

1838 Born: John Muir, Scottish-American environmentalist and author (d. 1914)

John Muir (April 21, 1838 – December 24, 1914) also known as "John of the Mountains" and "Father of the National Parks", was an influential Scottish-American naturalist, author, environmental philosopher, botanist, zoologist, glaciologist, and early advocate for the preservation of wilderness in the United States of America.

His letters, essays, and books describing his adventures in nature, especially in the Sierra Nevada, have been read by millions. His activism helped to preserve the Yosemite Valley and Sequoia National Park, and his example has served as an inspiration for the preservation of many other wilderness areas. The Sierra Club, which he co-founded, is a prominent American conservation organization. In his later life, Muir devoted most of his time to the preservation of the Western forests. As part of the campaign to make Yosemite a national park, Muir published two landmark articles on wilderness preservation in The Century Magazine, "The Treasures of the Yosemite" and "Features of the Proposed Yosemite National Park"; this helped support the push for U.S. Congress to pass a bill in 1890 establishing Yosemite National Park. The spiritual quality and enthusiasm toward nature expressed in his writings has inspired readers, including presidents and congressmen, to take action to help preserve large nature areas.

John Muir has been considered "an inspiration to both Scots and Americans". Muir's biographer, Steven J. Holmes, believes that Muir has become "one of the patron saints of twentieth-century American environmental activity," both political and recreational. As a result, his writings are commonly discussed in books and journals, and he has often been quoted by nature photographers such as Ansel Adams. "Muir has profoundly shaped the very categories through which Americans understand and envision their relationships with the natural world," writes Holmes.

Muir was noted for being an ecological thinker, political spokesman, and religious prophet, whose writings became a personal guide into nature for many people, making his name "almost ubiquitous" in the modern environmental consciousness. According to author William Anderson, Muir exemplified "the archetype of our oneness with the earth", while biographer Donald Worster says he believed his mission was "saving the American soul from total surrender to materialism." On April 21, 2013, the first John Muir Day was celebrated in Scotland, which marked the 175th anniversary of his birth, paying homage to the conservationist.

1864 Born: Max Weber, German economist and sociologist (d. 1920)

Maximilian Karl Emil Weber (21 April 1864 – 14 June 1920) was a German sociologist, philosopher, jurist, and political economist, who is regarded today as one of the most important theorists on the development of modern Western society. As his ideas would profoundly influence social theory and social research, Weber is often cited as among the four founders of sociology, alongside W. E. B. Du Bois, Émile Durkheim, and Karl Marx.

Unlike Durkheim, Weber did not believe in monocausal explanations, proposing instead that for any outcome there can be multiple causes. As such, he would be a key proponent of methodological anti-positivism, arguing for the study of social action through interpretive (rather than purely empiricist) methods, based on understanding the purpose and meanings that individuals attach to their own actions. Weber's main intellectual concern was in understanding the processes of rationalisation, secularisation, and "disenchantment", which he took to be the result of a new way of thinking about the world, associating such processes with the rise of capitalism and modernity. 

Weber is best known for his thesis of combining economic sociology and the sociology of religion, emphasising the importance of cultural influences embedded in religion as a means for understanding the genesis of capitalism (contrasting Marx's historical materialism). Weber would first elaborate his theory in his seminal work, The Protestant Ethic and the Spirit of Capitalism (1905), in which he attributes ascetic Protestantism as one of the major "elective affinities" involved in the rise of market-driven capitalism and the rational-legal nation-state in the Western world. Arguing the boosting of capitalism as a basic tenet of Protestantism, Weber would suggest that the spirit of capitalism is inherent to Protestant religious values. Protestant Ethic would form the earliest part in Weber's broader investigations into world religion, as he would go on to examine the religions of China and India, as well as ancient Judaism, with particular regard to their differing economic consequences and conditions of social stratification.

Through another major work, "Politics as a Vocation", Weber would define "the state" as an entity that successfully claims a "monopoly of the legitimate use of physical force within a given territory." He would also be the first to categorise social authority into distinct forms: charismatic, traditional, and rational-legal. Among these categories, Weber's analysis of bureaucracy would emphasize that modern state institutions are increasingly based on the latter (rational-legal authority).

Weber also made a variety of other contributions in economic history, theory, and methodology. His analysis of modernity and rationalisation would significantly influence the critical theory associated with the Frankfurt School. After the First World War, he was among the founders of the liberal German Democratic Party. He also ran unsuccessfully for a seat in parliament and served as advisor to the committee that drafted the ill-fated democratic Weimar Constitution of 1919. After contracting Spanish flu, he died of pneumonia in 1920, aged 56.

1910 Died: Mark Twain, American novelist, humorist, and critic (b. 1835)

Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), known by his pen name Mark Twain, was an American writer, humorist, entrepreneur, publisher, and lecturer. He was lauded as the "greatest humorist the United States has produced," and William Faulkner called him "the father of American literature". His novels include The Adventures of Tom Sawyer (1876) and its sequel, the Adventures of Huckleberry Finn (1884), the latter often called "The Great American Novel".

Twain was raised in Hannibal, Missouri, which later provided the setting for Tom Sawyer and Huckleberry Finn. He served an apprenticeship with a printer and then worked as a typesetter, contributing articles to the newspaper of his older brother Orion Clemens. He later became a riverboat pilot on the Mississippi River before heading west to join Orion in Nevada. He referred humorously to his lack of success at mining, turning to journalism for the Virginia City Territorial Enterprise. His humorous story, "The Celebrated Jumping Frog of Calaveras County", was published in 1865, based on a story that he heard at Angels Hotel in Angels Camp, California, where he had spent some time as a miner. The short story brought international attention and was even translated into French. His wit and satire, in prose and in speech, earned praise from critics and peers, and he was a friend to presidents, artists, industrialists, and European royalty.

Twain earned a great deal of money from his writings and lectures, but he invested in ventures that lost most of it—such as the Paige Compositor, a mechanical typesetter that failed because of its complexity and imprecision. He filed for bankruptcy in the wake of these financial setbacks, but in time overcame his financial troubles with the help of Henry Huttleston Rogers. He eventually paid all his creditors in full, even though his bankruptcy relieved him of having to do so. Twain was born shortly after an appearance of Halley's Comet, and he predicted that he would "go out with it" as well; he died the day after the comet made its closest approach to the Earth.
