Here are some events that happened on April 15th. It could be an event or a person that died or was born on that day


1452 Born: Leonardo da Vinci, Italian painter, sculptor, and architect (d. 1519)

Leonardo di ser Piero da Vinci (14/15 April 1452 – 2 May 1519), known as Leonardo da Vinci, was an Italian polymath of the Renaissance whose areas of interest included invention, drawing, painting, sculpture, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, paleontology, and cartography. He has been variously called the father of palaeontology, ichnology, and architecture, and is widely considered one of the greatest painters of all time (despite perhaps only 15 of his paintings having survived).

Born out of wedlock to a notary, Piero da Vinci, and a peasant woman, Caterina, in Vinci, in the region of Florence, Italy, Leonardo was educated in the studio of the renowned Italian painter Andrea del Verrocchio. Much of his earlier working life was spent in the service of Ludovico il Moro in Milan, and he later worked in Rome, Bologna and Venice. He spent his last three years in France, where he died in 1519.

Leonardo is renowned primarily as a painter. The Mona Lisa is the most famous of his works and the most popular portrait ever made. The Last Supper is the most reproduced religious painting of all time and his Vitruvian Man drawing is regarded as a cultural icon as well. Salvator Mundi was sold for a world record $450.3 million at a Christie's auction in New York, 15 November 2017, the highest price ever paid for a work of art. Leonardo's paintings and preparatory drawings—together with his notebooks, which contain sketches, scientific diagrams, and his thoughts on the nature of painting—compose a contribution to later generations of artists rivalled only by that of his contemporary Michelangelo.

Although he had no formal academic training, many historians and scholars regard Leonardo as the prime exemplar of the "Universal Genius" or "Renaissance Man", an individual of "unquenchable curiosity" and "feverishly inventive imagination." He is widely considered one of the most diversely talented individuals ever to have lived. According to art historian Helen Gardner, the scope and depth of his interests were without precedent in recorded history, and "his mind and personality seem to us superhuman, while the man himself mysterious and remote." Scholars interpret his view of the world as being based in logic, though the empirical methods he used were unorthodox for his time.

Leonardo is revered for his technological ingenuity. He conceptualized flying machines, a type of armoured fighting vehicle, concentrated solar power, an adding machine, and the double hull. Relatively few of his designs were constructed or even feasible during his lifetime, as the modern scientific approaches to metallurgy and engineering were only in their infancy during the Renaissance. Some of his smaller inventions, however, entered the world of manufacturing unheralded, such as an automated bobbin winder and a machine for testing the tensile strength of wire. He is also sometimes credited with the inventions of the parachute, helicopter, and tank.  He made substantial discoveries in anatomy, civil engineering, geology, optics, and hydrodynamics, but he did not publish his findings and they had little to no direct influence on subsequent science.

1707 Born: Leonhard Euler, Swiss mathematician and physicist (d. 1783)

Leonhard Euler (15 April 1707 – 18 September 1783) was a Swiss mathematician, physicist, astronomer, geographer, logician and engineer who made important and influential discoveries in many branches of mathematics, such as infinitesimal calculus and graph theory, while also making pioneering contributions to several branches such as topology and analytic number theory. He also introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of a mathematical function. He is also known for his work in mechanics, fluid dynamics, optics, astronomy and music theory. 

Euler was one of the most eminent mathematicians of the 18th century and is held to be one of the greatest in history. He is also widely considered to be the most prolific, as his collected works fill 92 volumes, more than anyone else in the field. He spent most of his adult life in Saint Petersburg, Russia, and in Berlin, then the capital of Prussia.

1800 Born: James Clark Ross, English captain and explorer (d. 1862)

Sir James Clark Ross (15 April 1800 – 3 April 1862) was a British Royal Navy officer and polar explorer known for his explorations of the Arctic, participating in two expeditions led by his uncle Sir John Ross, and four led by Sir William Parry, and, in particular, for his own Antarctic expedition from 1839 to 1843.

Ross was born in London, the nephew of Sir John Ross, under whom he entered the Royal Navy in 1812, accompanying him on Sir John's first Arctic voyage in search of a Northwest Passage in 1818. Between 1819 and 1827, Ross took part in four Arctic expeditions under Sir William Parry, and in 1829 to 1833, again served under his uncle on Sir John's second Arctic voyage. It was during this trip that a small party led by James Ross (including Thomas Abernethy) located the position of the North Magnetic Pole on 1 June 1831, on the Boothia Peninsula in the far north of Canada. It was on this trip, too, that Ross charted the Beaufort Islands, later renamed Clarence Islands by his uncle.

1865 – President Abraham Lincoln dies after being shot the previous evening by actor John Wilkes Booth. Vice President Andrew Johnson becomes President upon Lincoln's death.

Abraham Lincoln (February 12, 1809 – April 15, 1865) was an American statesman and lawyer who served as the 16th president of the United States from March 1861 until his assassination in April 1865. Lincoln led the nation through the American Civil War, its bloodiest war and its greatest moral, constitutional, and political crisis. He preserved the Union, abolished slavery, strengthened the federal government, and modernized the U.S. economy.

Born in Kentucky, Lincoln grew up on the frontier in a poor family. Self-educated, he became a lawyer, Whig Party leader, Illinois state legislator and Congressman. In 1849, he left government to resume his law practice, but angered by the success of Democrats in opening the prairie lands to slavery, reentered politics in 1854. He became a leader in the new Republican Party and gained national attention in 1858 for debating national Democratic leader Stephen A. Douglas in the 1858 Illinois Senate campaign. He then ran for President in 1860, sweeping the North and winning. Southern pro-slavery elements took his win as proof that the North was rejecting the constitutional rights of Southern states to practice slavery. They began the process of seceding from the union. To secure its independence, the new Confederate States of America fired on Fort Sumter, one of the few U.S. forts in the South. Lincoln called up volunteers and militia to suppress the rebellion and restore the Union.

As the leader of the moderate faction of the Republican Party, Lincoln confronted Radical Republicans, who demanded harsher treatment of the South; War Democrats, who rallied a large faction of former opponents into his camp; anti-war Democrats (called Copperheads), who despised him; and irreconcilable secessionists, who plotted his assassination. Lincoln fought the factions by pitting them against each other, by carefully distributing political patronage, and by appealing to the American people. His Gettysburg Address became an iconic call for nationalism, republicanism, equal rights, liberty, and democracy. He suspended habeas corpus, and he averted British intervention by defusing the Trent Affair. Lincoln closely supervised the war effort, including the selection of generals and the naval blockade that shut down the South's trade. As the war progressed, he maneuvered to end slavery, issuing the Emancipation Proclamation of 1863; ordering the Army to protect escaped slaves, encouraging border states to outlaw slavery, and pushing through Congress the Thirteenth Amendment to the United States Constitution, which outlawed slavery across the country.

Lincoln managed his own re-election campaign. He sought to reconcile his damaged nation by avoiding retribution against the secessionists. A few days after the Battle of Appomattox Court House, he was shot by John Wilkes Booth, an actor and Confederate sympathizer, on April 14, 1865, and died the following day. Abraham Lincoln is remembered as the United States' martyr hero. He is consistently ranked both by scholars and the public as among the greatest U.S. presidents.

1912 Born: Kim Il-sung, North Korean general and politician, 1st Supreme Leader of North Korea (d. 1994)

Kim Il-sung (15 April 1912 – 8 July 1994) was the first leader of North Korea, which he ruled from the country's establishment in 1948 until his death in 1994. He held the posts of Premier from 1948 to 1972 and President from 1972 to 1994. He was also the leader of the Workers' Party of Korea (WPK) from 1949 to 1994 (titled as Chairman from 1949 to 1966 and as General Secretary after 1966). Coming to power after the end of Japanese rule in 1945, he authorized the invasion of South Korea in 1950, triggering an intervention in defense of South Korea by the United Nations led by the United States. Following the military stalemate in the Korean War, a ceasefire was signed on 27 July 1953. He was the third longest-serving non-royal head of state/government in the 20th century, in office for more than 45 years.

Under his leadership, North Korea was established as a communist state with a publicly owned and planned economy. It had close political and economic relations with the Soviet Union. By the 1960s, North Korea briefly enjoyed a standard of living higher than the South, which was fraught with political instability and economic crises. The situation reversed in the 1970s, as a newly stable South Korea became an economic powerhouse fueled by Japanese and American investment, military aid, and internal economic development, while North Korea stagnated and then declined in the 1980s. Differences emerged between North Korea and the Soviet Union, chief among them being Kim Il-sung's philosophy of Juche, which focused on Korean nationalism, self-reliance, and socialism. Despite this, the country received funds, subsidies and aid from the USSR (and the Eastern Bloc) until the dissolution of the USSR in 1991. The resulting loss of economic aid adversely affected the North's economy, causing widespread famine in 1994. During this period, North Korea also remained critical of the United States defense force's presence in the region, which it considered imperialism, having seized the American ship USS Pueblo in 1968, which was part of an infiltration and subversion campaign to reunify the peninsula under North Korea's rule. He outlived Joseph Stalin by four decades and Mao Zedong by almost two and remained in power during the terms of office of six South Korean Presidents, ten US Presidents, and the rule of British monarchs George VI and later his daughter Elizabeth II. Known as the Great Leader (Suryong), he established a personality cult which dominates domestic politics in North Korea.

At the 6th WPK Congress in 1980, his oldest son Kim Jong-il was elected as a Presidium member and chosen as his heir apparent to the supreme leadership. Kim Il-sung's birthday is a public holiday in North Korea called the "Day of the Sun". In 1998, Kim Il-sung was declared "eternal President of the Republic". During his rule, North Korea was molded into a totalitarian state responsible for widespread human rights abuses.

2019 – The cathedral of Notre-Dame de Paris in France is seriously damaged by a large fire.

Notre-Dame de Paris, referred to simply as Notre-Dame, is a medieval Catholic cathedral on the Île de la Cité in the 4th arrondissement of Paris. The cathedral was consecrated to the Virgin Mary and considered to be one of the finest examples of French Gothic architecture. Its pioneering use of the rib vault and flying buttress, its enormous and colourful rose windows, as well as the naturalism and abundance of its sculptural decoration set it apart from the earlier Romanesque style. Major components that make Notre Dame stand out include one of the world's largest organs and its immense church bells.

The cathedral's construction began in 1160 under Bishop Maurice de Sully and was largely complete by 1260, though it was modified frequently in the following centuries. In the 1790s, Notre-Dame suffered desecration during the French Revolution; much of its religious imagery was damaged or destroyed. In the 19th century, the cathedral was the site of the coronation of Napoleon I and funerals of many Presidents of the Republic.

Popular interest in the cathedral blossomed soon after the publication, in 1831, of Victor Hugo's novel Notre-Dame de Paris (better known in English as The Hunchback of Notre-Dame). This led to a major restoration project between 1844 and 1864, supervised by Eugène Viollet-le-Duc. The liberation of Paris was celebrated within Notre-Dame in 1944 with the singing of the Magnificat. Beginning in 1963, the cathedral's façade was cleaned of centuries of soot and grime. Another cleaning and restoration project was carried out between 1991 and 2000.

On 15 April 2019, just before 18:20 CEST, a structure fire broke out beneath the roof of Notre-Dame de Paris cathedral in Paris. By the time it was extinguished, the building's spire and most of its roof had been destroyed and its upper walls severely damaged; extensive damage to the interior was prevented by its stone vaulted ceiling, which largely contained the burning roof as it collapsed. Many works of art and religious relics were moved to safety early in the emergency, but others suffered some smoke damage, and some exterior art was damaged or destroyed. The cathedral's altar, two pipe organs, and its three 13th-century rose windows suffered little to no damage. Three emergency workers were injured. Contamination of the site and the nearby environment resulted.

President Emmanuel Macron said that the cathedral would be restored by 2024, and launched a fundraising campaign which brought in pledges of over €1 billion as of 22 April 2019. A complete restoration could require twenty years or more.

On 25 December 2019, the Notre Dame Cathedral did not host Christmas services for the first time since the French Revolution.

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


1743 Born: Thomas Jefferson, American lawyer and politician, 3rd President of the United States (d. 1826)

Thomas Jefferson (April 13, 1743 – July 4, 1826) was an American statesman, diplomat, lawyer, architect, and Founding Father who served as the third president of the United States from 1801 to 1809. Previously, he had served as the second vice president of the United States from 1797 to 1801. The principal author of the Declaration of Independence, Jefferson was a proponent of democracy, republicanism, and individual rights motivating American colonists to break from the Kingdom of Great Britain and form a new nation; he produced formative documents and decisions at both the state and national level.

During the American Revolution, he represented Virginia in the Continental Congress that adopted the Declaration, drafted the law for religious freedom as a Virginia legislator, and served as the second Governor of Virginia from 1779 to 1781, during the American Revolutionary War. He became the United States Minister to France in May 1785, and subsequently, the nation's first secretary of state under President George Washington from 1790 to 1793. Jefferson and James Madison organized the Democratic-Republican Party to oppose the Federalist Party during the formation of the First Party System. With Madison, he anonymously wrote the provocative Kentucky and Virginia Resolutions in 1798 and 1799, which sought to strengthen states' rights by nullifying the federal Alien and Sedition Acts.

As president, Jefferson pursued the nation's shipping and trade interests against Barbary pirates and aggressive British trade policies. He also organized the Louisiana Purchase, almost doubling the country's territory. As a result of peace negotiations with France, his administration reduced military forces. He was reelected in 1804. Jefferson's second term was beset with difficulties at home, including the trial of former vice president Aaron Burr. American foreign trade was diminished when Jefferson implemented the Embargo Act of 1807, in response to British threats to U.S. shipping. In 1803, Jefferson began a controversial process of Indian tribe removal to the newly organized Louisiana Territory, and he signed the Act Prohibiting Importation of Slaves in 1807. After retiring from public office, Jefferson founded the University of Virginia.

Jefferson, while primarily a planter, lawyer and politician, mastered many disciplines, which ranged from surveying and mathematics to horticulture and mechanics. He was an architect in the classical tradition. Jefferson's keen interest in religion and philosophy led to his presidency of the American Philosophical Society; he shunned organized religion but was influenced by both Christianity and deism. A philologist, Jefferson knew several languages. He was a prolific letter writer and corresponded with many prominent people. His only full-length book is Notes on the State of Virginia (1785), considered perhaps the most important American book published before 1800.

Although Jefferson is regarded as a leading spokesman for democracy and republicanism in the era of the Enlightenment, some modern scholarship has been critical of Jefferson, finding a contradiction between his ownership and trading of many slaves that worked his plantations, and his famous declaration that "all men are created equal". Although the matter remains a subject of debate, most historians believe that Jefferson had a sexual relationship with his slave Sally Hemings, a mixed-race woman who was a half-sister to his late wife and that he fathered at least one of her children. Presidential scholars and historians generally praise Jefferson's public achievements, including his advocacy of religious freedom and tolerance in Virginia. Jefferson continues to rank highly among U.S. presidents.

1808 Born: Antonio Meucci, Italian-American engineer (d. 1889)

Antonio Santi Giuseppe Meucci (13 April 1808 – 18 October 1889) was an Italian inventor and an associate of Giuseppe Garibaldi, a major political figure in the history of Italy. Meucci is best known for developing a voice-communication apparatus that several sources credit as the first telephone.

Meucci set up a form of voice-communication link in his Staten Island, New York, home that connected the second-floor bedroom to his laboratory. He submitted a patent caveat for his telephonic device to the U.S. Patent Office in 1871, but there was no mention of electromagnetic transmission of vocal sound in his caveat. In 1876, Alexander Graham Bell was granted a patent for the electromagnetic transmission of vocal sound by undulatory electric current. Despite the longstanding general crediting of Bell with the accomplishment, the Italian Ministry of Cultural Heritage and Activities supported celebrations of Meucci's 200th birthday in 2008 using the title "Inventore del telefono" (Inventor of the telephone). The U.S. House of Representatives also honored Meucci in a resolution in 2002 for having had some role in the development of the telephone, although the U.S. Senate did not join the resolution and the interpretation of the resolution is disputed.

1943 – The Jefferson Memorial is dedicated in Washington, D.C., on the 200th anniversary of President Thomas Jefferson's birth.

The Jefferson Memorial is a presidential memorial built in Washington, D.C. between 1939 and 1943, under the sponsorship of President Franklin D. Roosevelt. For Roosevelt it was a suitable memorial to the Founding Father of the United States, and the founder of the Democratic-Republican Party, Thomas Jefferson.

The neoclassical Memorial building is situated in West Potomac Park on the shore of the Tidal Basin off the Washington Channel of the Potomac River. It was designed by the architect John Russell Pope and built by the Philadelphia contractor John McShain. Construction of the building began in 1939 and was completed in 1943. The bronze statue of Jefferson was added in 1947.

Pope made references to the Roman Pantheon and Jefferson's own design for the Rotunda at the University of Virginia. The Jefferson Memorial, and the White House located directly north, form one of the main anchor points in the area of the National Mall in D.C. The Washington Monument, just east of the axis on the national Mall, was intended to be located at the intersection of the White House and the site for the Jefferson Memorial to the south, but soft swampy ground which defied 19th century engineering required it be sited to the east.

The Jefferson Memorial is managed by the National Park Service of the United States Department of the Interior under its National Mall and Memorial Parks division. In 2007, it was ranked fourth on the "List of America's Favorite Architecture" by the American Institute of Architects.

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


1492 Died: Lorenzo de' Medici, Italian ruler (b. 1449)

Lorenzo de' Medici (1 January 1449 – 8 April 1492) was an Italian statesman, de facto ruler of the Florentine Republic and the most powerful and enthusiastic patron of Renaissance culture in Italy. Also known as Lorenzo the Magnificent (Lorenzo il Magnifico) by contemporary Florentines, he was a magnate, diplomat, politician and patron of scholars, artists and poets. As a patron, he is best known for his sponsorship of artists such as Botticelli and Michelangelo. He held the balance of power within the Italic League, an alliance of states that stabilized political conditions on the Italian peninsula for decades, and his life coincided with the mature phase of the Italian Renaissance and the Golden Age of Florence. The Peace of Lodi of 1454 that he helped maintain among the various Italian states collapsed with his death. He is buried in the Medici Chapel in Florence.

1818 Born:  Christian IX of Denmark (d. 1906)

Christian IX (8 April 1818 – 29 January 1906) was King of Denmark from 1863 until his death in 1906. From 1863 to 1864, he was concurrently Duke of Schleswig, Holstein and Lauenburg.

Growing up as a prince of Schleswig-Holstein-Sonderburg-Glücksburg, a junior branch of the House of Oldenburg which had ruled Denmark since 1448, Christian was originally not in the immediate line of succession to the Danish throne. However, in 1852, Christian was chosen as heir to the Danish monarchy in light of the expected extinction of the senior line of the House of Oldenburg. Upon the death of King Frederick VII of Denmark in 1863, Christian (who was both Frederick's uncle and cousin) acceded to the throne as the first Danish monarch of the House of Glücksburg.

The beginning of his reign was marked by the Danish defeat in the Second Schleswig War and the subsequent loss of the duchies of Schleswig, Holstein and Lauenburg which made the king immensely unpopular. The following years of his reign were dominated by political disputes as Denmark had only become a constitutional monarchy in 1849 and the balance of power between the sovereign and parliament was still in dispute. In spite of his initial unpopularity and the many years of political strife, where the king was in conflict with large parts of the population, his popularity recovered towards the end of his reign, and he became a national icon due to the length of his reign and the high standards of personal morality with which he was identified.

Christian married his second cousin, Princess Louise of Hesse-Kassel, in 1842. Their six children married into other royal families across Europe, earning him the sobriquet "the father-in-law of Europe". Among his descendants are Margrethe II of Denmark, Elizabeth II of the United Kingdom, Philippe of Belgium, Harald V of Norway, Felipe VI of Spain, Grand Duke Henri of Luxembourg, Constantine II of Greece, Queen Anne-Marie of Greece, Queen Sofia of Spain and Prince Philip, Duke of Edinburgh

1835 Died: Wilhelm von Humboldt, German philosopher, academic, and politician, Interior Minister of Prussia (b. 1767 )

Friedrich Wilhelm Christian Karl Ferdinand von Humboldt (22 June 1767 – 8 April 1835) was a Prussian philosopher, linguist, government functionary, diplomat, and founder of the Humboldt University of Berlin, which was named after him in 1949 (and also after his younger brother, Alexander von Humboldt, a naturalist).

He is especially remembered as a linguist who made important contributions to the philosophy of language, ethnolinguistics and to the theory and practice of education. He made a major contribution to the development of liberalism by envisioning education as a means of realizing individual possibility rather than a way of drilling traditional ideas into youth to suit them for an already established occupation or social role. In particular, he was the architect of the Humboldtian education ideal, which was used from the beginning in Prussia as a model for its system of public education, as well as in the United States and Japan. He was elected as a member of the American Philosophical Society in 1822.

1875 Born: Albert I of Belgium (d. 1934)

Albert I (8 April 1875 – 17 February 1934) reigned as King of the Belgians from 1909 to 1934. This was an eventful period in the history of Belgium, which included the period of World War I (1914–1918), when 90 percent of Belgium was overrun, occupied, and ruled by the German Empire. Other crucial issues included the adoption of the Treaty of Versailles, the ruling of the Belgian Congo as an overseas possession of the Kingdom of Belgium along with the League of Nations mandate of Ruanda-Urundi, the reconstruction of Belgium following the war, and the first five years of the Great Depression (1929–1934). King Albert died in a mountaineering accident in eastern Belgium in 1934, at the age of 58, and he was succeeded by his son Leopold III (r. 1934–1951).

1973 Died: Pablo Picasso, Spanish painter and sculptor (b. 1881)

Pablo Ruiz Picasso (25 October 1881 – 8 April 1973) was a Spanish painter, sculptor, printmaker, ceramicist, stage designer, poet and playwright who spent most of his adult life in France. Regarded as one of the most influential artists of the 20th century, he is known for co-founding the Cubist movement, the invention of constructed sculpture, the co-invention of collage, and for the wide variety of styles that he helped develop and explore. Among his most famous works are the proto-Cubist Les Demoiselles d'Avignon (1907), and Guernica (1937), a dramatic portrayal of the bombing of Guernica by the German and Italian airforces during the Spanish Civil War.

Picasso demonstrated extraordinary artistic talent in his early years, painting in a naturalistic manner through his childhood and adolescence. During the first decade of the 20th century, his style changed as he experimented with different theories, techniques, and ideas. After 1906, the Fauvist work of the slightly older artist Henri Matisse motivated Picasso to explore more radical styles, beginning a fruitful rivalry between the two artists, who subsequently were often paired by critics as the leaders of modern art.

Picasso's work is often categorized into periods. While the names of many of his later periods are debated, the most commonly accepted periods in his work are the Blue Period (1901–1904), the Rose Period (1904–1906), the African-influenced Period (1907–1909), Analytic Cubism (1909–1912), and Synthetic Cubism (1912–1919), also referred to as the Crystal period. Much of Picasso's work of the late 1910s and early 1920s is in a neoclassical style, and his work in the mid-1920s often has characteristics of Surrealism. His later work often combines elements of his earlier styles.

Exceptionally prolific throughout the course of his long life, Picasso achieved universal renown and immense fortune for his revolutionary artistic accomplishments, and became one of the best-known figures in 20th-century art.

Here are some events that happened on April 6th. It could be an event or a person that died or was born on that day


1483 Born: Raphael, Italian painter and architect (d. 1520)

Raffaello Sanzio da Urbino (March 28 or April 6, 1483 – April 6, 1520), known as Raphael, was an Italian painter and architect of the High Renaissance. His work is admired for its clarity of form, ease of composition, and visual achievement of the Neoplatonic ideal of human grandeur. Together with Michelangelo and Leonardo da Vinci, he forms the traditional trinity of great masters of that period.

Raphael was enormously productive, running an unusually large workshop and, despite his early death at 37, leaving a large body of work. Many of his works are found in the Vatican Palace, where the frescoed Raphael Rooms were the central, and the largest, work of his career. The best known work is The School of Athens in the Vatican Stanza della Segnatura. After his early years in Rome, much of his work was executed by his workshop from his drawings, with considerable loss of quality. He was extremely influential in his lifetime, though outside Rome his work was mostly known from his collaborative printmaking.

After his death, the influence of his great rival Michelangelo was more widespread until the 18th and 19th centuries, when Raphael's more serene and harmonious qualities were again regarded as the highest models. His career falls naturally into three phases and three styles, first described by Giorgio Vasari: his early years in Umbria, then a period of about four years (1504–1508) absorbing the artistic traditions of Florence, followed by his last hectic and triumphant twelve years in Rome, working for two Popes and their close associates.

1528 Died: Albrecht Dürer, German painter, engraver, and mathematician (b. 1471)

Albrecht Dürer (21 May 1471 – 6 April 1528), sometimes spelt in English as Durer or Duerer, without umlaut, was a German painter, printmaker, and theorist of the German Renaissance. Born in Nuremberg, Dürer established his reputation and influence across Europe when he was in his twenties due to his high-quality woodcut prints. He was in communication with the major Italian artists of his time, including Raphael, Giovanni Bellini and Leonardo da Vinci, and from 1512 he was patronized by Emperor Maximilian I. Dürer is commemorated by both the Lutheran and Episcopal Churches.

Dürer's vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts, such as the Apocalypse series (1498), are more Gothic than the rest of his work. His well-known engravings include the Knight, Death and the Devil (1513), Saint Jerome in his Study (1514) and Melencolia I (1514), which has been the subject of extensive analysis and interpretation. His watercolours also mark him as one of the first European landscape artists, while his ambitious woodcuts revolutionized the potential of that medium.

Dürer's introduction of classical motifs into Northern art, through his knowledge of Italian artists and German humanists, has secured his reputation as one of the most important figures of the Northern Renaissance. This is reinforced by his theoretical treatises, which involve principles of mathematics, perspective, and ideal proportions.

Albrecht Dürer has been credited with inventing the basic principle of ray tracing, a technique used in modern computer graphics.

1829 Died: Niels Henrik Abel, Norwegian mathematician and theorist (b. 1802)

Niels Henrik Abel (5 August 1802 – 6 April 1829) was a Norwegian mathematician who made pioneering contributions in a variety of fields. His most famous single result is the first complete proof demonstrating the impossibility of solving the general quintic equation in radicals. This question was one of the outstanding open problems of his day, and had been unresolved for over 250 years. He was also an innovator in the field of elliptic functions, discoverer of Abelian functions. He made his discoveries while living in poverty and died at the age of 26 from tuberculosis.

Most of his work was done in six or seven years of his working life. Regarding Abel, the French mathematician Charles Hermite said: "Abel has left mathematicians enough to keep them busy for five hundred years." Another French mathematician, Adrien-Marie Legendre, said: "quelle tête celle du jeune Norvégien!" ("what a head the young Norwegian has!"). 

The Abel Prize in mathematics, originally proposed in 1899 to complement the Nobel Prizes, is named in his honour.

John Tyler (March 29, 1790 – January 18, 1862) was the tenth president of the United States from 1841 to 1845 after briefly serving as the tenth vice president in 1841; he was elected vice president on the 1840 Whig ticket with President William Henry Harrison. Tyler ascended to the presidency after Harrison's death in April 1841, only a month after the start of the new administration. He was a stalwart supporter and advocate of states' rights, and he adopted nationalist policies as president only when they did not infringe on the powers of the states. His unexpected rise to the presidency posed a threat to the presidential ambitions of Henry Clay and other politicians, and left Tyler estranged from both major political parties.

Tyler was born to a prominent Virginia family and became a national figure at a time of political upheaval. In the 1820s, the nation's only political party was the Democratic-Republican Party, and it split into factions. Tyler was initially a Democrat, but he opposed Andrew Jackson during the Nullification Crisis, seeing Jackson's actions as infringing on states' rights, and he criticized Jackson's expansion of executive power during the Bank War. This led Tyler to ally with the Whig Party. He served as a Virginia state legislator, governor, U.S. representative, and U.S. senator. He was put on the 1840 presidential ticket to attract states' rights Southerners to a Whig coalition to defeat Martin Van Buren's re-election bid.

President Harrison died just one month after taking office, and Tyler became the first vice president to succeed to the presidency without election. He served longer than any president in U.S. history not elected to the office. To forestall constitutional uncertainty, Tyler immediately took the oath of office, moved into the White House, and assumed full presidential powers—a precedent that governed future successions and was codified in the Twenty-fifth Amendment. Tyler signed into law some of the Whig-controlled Congress's bills, but he was a strict constructionist and vetoed the party's bills to create a national bank and raise the tariff rates. He believed that the president should set policy rather than Congress, and he sought to bypass the Whig establishment, most notably senator Henry Clay of Kentucky. Most of Tyler's Cabinet resigned soon into his term, and the Whigs dubbed him His Accidency and expelled him from the party. Tyler was the first president to see his veto of legislation overridden by Congress. He faced a stalemate on domestic policy, although he had several foreign-policy achievements, including the Webster–Ashburton Treaty with Britain and the Treaty of Wanghia with Qing China.

The Republic of Texas separated from Mexico in 1836. Tyler was a firm believer in manifest destiny and saw its annexation as providing an economic advantage to the United States, so he worked diligently to make it happen. He initially sought election to a full term as president, but he failed to gain the support of either Whigs or Democrats and withdrew in support of Democrat James K. Polk, who favored the annexation of Texas. Polk won the election, Tyler signed a bill to annex Texas three days before leaving office, and Polk completed the process. When the American Civil War began in 1861, Tyler sided with the Confederacy and won election to the Confederate House of Representatives shortly before his death. Some scholars have praised Tyler's political resolve, but his presidency is generally held in low regard by historians. He is considered an obscure president, with little presence in American cultural memory.

1890 Born: Anthony Fokker, Dutch engineer and businessman, founded Fokker Aircraft Manufacturer (d. 1939)

Anton Herman Gerard "Anthony" Fokker (6 April 1890 – 23 December 1939) was a Dutch aviation pioneer and aircraft manufacturer. He is most famous for the fighter aircraft he produced in Germany during the First World War such as the Eindecker monoplanes, the Dr.1 triplane and the D.VII biplane.

After the Treaty of Versailles forbade Germany to produce airplanes, Fokker moved his business to the Netherlands. There his company was responsible for a variety of successful aircraft including the Fokker trimotor, a successful passenger aircraft of the inter-war years. He died in New York in 1939. Later authors suggest he was personally charismatic but unscrupulous in business and a controversial character.

1896 – In Athens, the opening of the first modern Olympic Games is celebrated, 1,500 years after the original games are banned by Roman emperor Theodosius I.


The 1896 Summer Olympics (Greek: Θερινοί Ολυμπιακοί Αγώνες 1896, romanized: Therinoí Olympiakoí Agónes 1896), officially known as the Games of the I Olympiad, was the first international Olympic Games held in modern history. Organised by the International Olympic Committee (IOC), which had been created by Pierre de Coubertin, it was held in Athens, Greece, from 6 to 15 April 1896.

Fourteen nations and 241, all male, athletes took part in the games. Participants were all European, or living in Europe, with the exception of the United States team. Winners were given a silver medal, while runners-up received a copper medal. Retroactively, the IOC has converted these to gold and silver, and awarded bronze medals to third placed athletes. Ten of the 14 participating nations earned medals. The United States won the most gold medals, 11, host nation Greece won the most medals overall, 46. The highlight for the Greeks was the marathon victory by their compatriot Spyridon Louis. The most successful competitor was German wrestler and gymnast Carl Schuhmann, who won four events. Over 65% of the competing athletes were Greek.

Athens had been unanimously chosen to stage the inaugural modern Games during a congress organised by Coubertin in Paris on 23 June 1894, during which the IOC was also created, because Greece was the birthplace of the Ancient Olympic Games. The main venue was the Panathenaic Stadium, where athletics and wrestling took place; other venues included the Neo Phaliron Velodrome for cycling, and the Zappeion for fencing. The opening ceremony was held in the Panathenaic Stadium on 6 April, during which most of the competing athletes were aligned on the infield, grouped by nation. After a speech by the president of the organising committee, Crown Prince Constantine, his father officially opened the Games. Afterwards, nine bands and 150 choir singers performed an Olympic Hymn, composed by Spyridon Samaras, with words by poet Kostis Palamas.

The 1896 Olympics were regarded as a great success. The Games had the largest international participation of any sporting event to that date. The Panathenaic Stadium overflowed with the largest crowd ever to watch a sporting event. After the Games, Coubertin and the IOC were petitioned by several prominent figures, including Greece's King George and some of the American competitors in Athens, to hold all the following Games in Athens. However, the 1900 Summer Olympics were already planned for Paris and, except for the Intercalated Games of 1906, the Olympics did not return to Greece until the 2004 Summer Olympics, 108 years later.

2005 Died: Rainier III, Prince of Monaco (b. 1923)

Rainier III (Rainier Louis Henri Maxence Bertrand Grimaldi; 31 May 1923 – 6 April 2005) was the Prince of Monaco from 1949 to his death in 2005. Rainier ruled the Principality of Monaco for almost 56 years, making him one of the longest ruling monarchs in European history. Though internationally known for his marriage to American actress Grace Kelly, he was also responsible for reforms to Monaco's constitution and for expanding the principality's economy from its traditional casino gambling base to its current tax haven role. Gambling accounts for only approximately three per cent of the nation's annual revenue today; when Rainier ascended the throne in 1949, it accounted for more than 95 per cent.
