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

1848 Died: John Quincy Adams, American politician, 6th President of the United States (b. 1767)

John Quincy Adams (July 11, 1767 – February 23, 1848) was an American statesman, diplomat, lawyer, and diarist who served as the sixth president of the United States, from 1825 to 1829. He previously served as the eighth United States Secretary of State from 1817 to 1825. During his long diplomatic and political career, Adams also served as an ambassador, and as a member of the United States Senate and House of Representatives representing Massachusetts. He was the eldest son of John Adams, who served as the second US president from 1797 to 1801, and First Lady Abigail Adams. Initially a Federalist like his father, he won election to the presidency as a member of the Democratic-Republican Party, and in the mid-1830s became affiliated with the Whig Party.

Born in what is now Quincy, Massachusetts (then part of the town of Braintree), Adams spent much of his youth in Europe, where his father served as a diplomat. After returning to the United States, Adams established a successful legal practice in Boston. In 1794, President George Washington appointed Adams as the U.S. ambassador to the Netherlands, and Adams would serve in high-ranking diplomatic posts until 1801, when Thomas Jefferson took office as president. Federalist leaders in Massachusetts arranged for Adams's election to the United States Senate in 1802, but Adams broke with the Federalist Party over foreign policy and was denied re-election. In 1809, Adams was appointed as the U.S. ambassador to Russia by President James Madison, a member of the Democratic-Republican Party. Adams held diplomatic posts for the duration of Madison's presidency, and he served as part of the American delegation that negotiated an end to the War of 1812. In 1817, newly elected president James Monroe selected Adams as his Secretary of State. In that role, Adams negotiated the Adams–Onís Treaty, which provided for the American acquisition of Florida. He also helped formulate the Monroe Doctrine, which became a key tenet of U.S. foreign policy.

The 1824 presidential election was contested by Adams, Andrew Jackson, William H. Crawford, and Henry Clay, all of whom were members of the Democratic-Republican Party. As no candidate won a majority of the electoral vote, the House of Representatives held a contingent election to determine the president, and Adams won that contingent election with the support of Clay. As president, Adams called for an ambitious agenda that included federally funded infrastructure projects, the establishment of a national university, and engagement with the countries of Latin America, but many of his initiatives were defeated in Congress. During Adams's presidency, the Democratic-Republican Party polarized into two major camps: one group, known as the National Republican Party, supported President Adams, while the other group, known as the Democratic Party, was led by Andrew Jackson. The Democrats proved to be more effective political organizers than Adams and his National Republican supporters, and Jackson decisively defeated Adams in the 1828 presidential election, the second president (after his father) to fail re-election.

Rather than retiring from public service, Adams won election to the House of Representatives, where he would serve from 1831 to his death in 1848. He remains the only ex-president to be elected to the chamber (although John Tyler was elected a Confederate representative, dying before seated). Narrowly failing attempts at Governor of Massachusetts and re-election to the Senate, Adams joined the Anti-Masonic Party in the early 1830s before becoming a member of the Whig Party, which united those opposed to President Jackson. During his time in Congress, Adams became increasingly critical of slavery and of the Southern leaders who he believed controlled the Democratic Party. He was particularly opposed to the annexation of Texas and the Mexican–American War, which he saw as a war to extend slavery and its political grip on Congress. He also led the repeal of the "gag rule", which had prevented the House of Representatives from debating petitions to abolish slavery. Historians generally concur that Adams was one of the greatest diplomats and secretaries of state in American history; they typically rank him as an average president, as he had an ambitious agenda but could not get it passed by Congress.

1854 – The official independence of the Orange Free State is declared.

The Orange Free State (Dutch: Oranje Vrijstaat, Afrikaans: Oranje-Vrystaat, abbreviated as OVS) was an independent Boer sovereign republic under British suzerainty in Southern Africa during the second half of the 19th century, which ceased to exist after it was defeated and surrendered to the British Empire at the end of the Second Boer War in 1902. It is one of the three historical precursors to the present-day Free State province.

Extending between the Orange and Vaal rivers, its borders were determined by the United Kingdom of Great Britain and Ireland in 1848 when the region was proclaimed as the Orange River Sovereignty, with a British Resident based in Bloemfontein. Bloemfontein and the southern parts of the Sovereignty had previously been settled by Griqua and by Trekboere from the Cape Colony.

The Voortrekker Republic of Natalia, founded in 1837, administered the northern part of the territory through a landdrost based at Winburg. This northern area was later in federation with the Republic of Potchefstroom which eventually formed part of the South African Republic (Transvaal).

Following the granting of sovereignty to the Transvaal Republic, the British recognised the independence of the Orange River Sovereignty and the country officially became independent as the Orange Free State on 23 February 1854, with the signing of the Orange River Convention. The new republic incorporated the Orange River Sovereignty and continued the traditions of the Winburg-Potchefstroom Republic.

The Orange Free State developed into a politically and economically successful republic and for the most part enjoyed good relationships with its neighbors. It was annexed as the Orange River Colony in 1900. It ceased to exist as an independent Boer republic on 31 May 1902 with the signing of the Treaty of Vereeniging at the conclusion of the Second Boer War. Following a period of direct rule by the British, it attained self-government in 1907 and joined the Union of South Africa in 1910 as the Orange Free State Province, along with the Cape Province, Natal, and the Transvaal. In 1961, the Union of South Africa became the Republic of South Africa.

The Republic's name derives partly from the Orange River, which in turn was named in honor of the Dutch ruling family, the House of Orange, by the Dutch explorer Robert Jacob Gordon. The official language in the Orange Free State was Dutch.

1855 Died: Carl Friedrich Gauss, German mathematician, astronomer, and physicist (b. 1777)

Johann Carl Friedrich Gauss (Latin: Carolus Fridericus Gauss; 30 April 1777 – 23 February 1855) was a German mathematician and physicist who made significant contributions to many fields in mathematics and science. Sometimes referred to as the Princeps mathematicorum (Latin for '"the foremost of mathematicians"') and "the greatest mathematician since antiquity", Gauss had an exceptional influence in many fields of mathematics and science, and is ranked among history's most influential mathematicians.

1898 – Émile Zola is imprisoned in France after writing J'Accuse…!, a letter accusing the French government of antisemitism and wrongfully imprisoning Captain Alfred Dreyfus.

Émile Édouard Charles Antoine Zola (2 April 1840 – 29 September 1902) was a French novelist, playwright, journalist, the best-known practitioner of the literary school of naturalism, and an important contributor to the development of theatrical naturalism. He was a major figure in the political liberalization of France and in the exoneration of the falsely accused and convicted army officer Alfred Dreyfus, which is encapsulated in the renowned newspaper headline J'Accuse…! Zola was nominated for the first and second Nobel Prize in Literature in 1901 and 1902

More than half of Zola's novels were part of a set of 20 collectively known as Les Rougon-Macquart, about a family under the Second Empire. Unlike Balzac, who in the midst of his literary career resynthesized his work into La Comédie Humaine, Zola from the start, at the age of 28, had thought of the complete layout of the series. Set in France's Second Empire, in the context of Baron Haussman's changing Paris, the series traces the "environmental" influences of violence, alcohol, and prostitution which became more prevalent during the second wave of the Industrial Revolution. The series examines two branches of a family—the respectable (that is, legitimate) Rougons and the disreputable (illegitimate) Macquarts—for five generations.

As he described his plans for the series, "I want to portray, at the outset of a century of liberty and truth, a family that cannot restrain itself in its rush to possess all the good things that progress is making available and is derailed by its own momentum, the fatal convulsions that accompany the birth of a new world."

He is considered to be a significant influence on those writers that are credited with the creation of the so-called new journalism; Wolfe, Capote, Thompson, Mailer, Didion, Talese and others. Tom Wolfe wrote that his goal in writing fiction was to document contemporary society in the tradition of John Steinbeck, Charles Dickens, and Émile Zola.

1934 – Leopold III becomes King of Belgium.

Leopold III (3 November 1901 – 25 September 1983) was King of the Belgians from 1934 until 1951, when he abdicated in favor of the heir apparent, his son Baudouin. From 1944 until 1950, Leopold's brother, Charles, served as prince regent while Leopold was declared unable to reign. Leopold's controversial actions during the Second World War resulted in a political crisis known as the Royal Question. In 1950, the debate about whether Leopold could resume his royal functions escalated. Following a referendum, Leopold was allowed to return from exile to Belgium, but the continuing political instability pressured him to abdicate in 1951.

Leopold was born in Brussels and succeeded to the throne of Belgium on 23 February 1934, following the death of his father King Albert I.

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

1512 Died: Amerigo Vespucci, Italian cartographer and explorer (b. 1454)

Amerigo Vespucci (March 9, 1454 – February 22, 1512) was an Italian explorer, financier, navigator, and cartographer from the Republic of Florence. Sailing for Portugal around 1501–1502, Vespucci demonstrated that Brazil and the West Indies were not Asia's eastern outskirts (as initially conjectured from Columbus' voyages) but a separate continent described as the "New World". In 1507, the new continent was named America after the Latin version of Vespucci's first name.  Vespucci then became a citizen of the Crown of Castile and died in Seville (1512).

1732 Born: George Washington, American general and politician, 1st President of the United States (d. 1799)

George Washington (February 22, 1732 – December 14, 1799) was an American political leader, military general, statesman, and Founding Father who served as the first president of the United States from 1789 to 1797. Previously, he led Patriot forces to victory in the nation's War for Independence. He presided at the Constitutional Convention of 1787, which established the U.S. Constitution and a federal government. Washington has been called the "Father of His Country" for his manifold leadership in the formative days of the new nation.

Washington received his initial military training and command with the Virginia Regiment during the French and Indian War. He was later elected to the Virginia House of Burgesses and was named a delegate to the Continental Congress, where he was appointed Commanding General of the Continental Army. He commanded American forces, allied with France, in the defeat and surrender of the British during the Siege of Yorktown. He resigned his commission after the Treaty of Paris in 1783.

Washington played a key role in adopting and ratifying the Constitution and was then twice elected president by the Electoral College. He implemented a strong, well-financed national government while remaining impartial in a fierce rivalry between cabinet members Thomas Jefferson and Alexander Hamilton. During the French Revolution, he proclaimed a policy of neutrality while sanctioning the Jay Treaty. He set enduring precedents for the office of president, including the title "Mr. President", and his Farewell Address is widely regarded as a pre-eminent statement on republicanism.

Washington owned slaves, and, in order to preserve national unity, he supported measures passed by Congress to protect slavery. He later became troubled with the institution of slavery and freed his slaves in a 1799 will. He endeavored to assimilate Native Americans into Anglo-American culture, but combated indigenous resistance during instances of violent conflict. He was a member of the Anglican Church and the Freemasons, and he urged broad religious freedom in his roles as general and president. Upon his death, he was eulogized as "first in war, first in peace, and first in the hearts of his countrymen". He has been memorialized by monuments, art, geographical locations, stamps, and currency, and many scholars and polls rank him among the greatest U.S. presidents.

1840 Born: August Bebel, German theorist and politician (d. 1913)

Ferdinand August Bebel (22 February 1840 – 13 August 1913) was a German socialist politician, writer, and orator. He is best remembered as one of the founders of the Social Democratic Workers' Party of Germany (SDAP) in 1869, which in 1875 merged with the General German Workers' Association into the Socialist Workers' Party of Germany (SAPD). During the repression under the terms of the Anti-Socialist Laws, Bebel became the leading figure of the social democratic movement in Germany and from 1892 until his death served as chairman of the Social Democratic Party of Germany.

1857 Born: Heinrich Hertz, German physicist, philosopher, and academic (d. 1894)

Heinrich Rudolf Hertz (22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism. The unit of frequency, cycle per second, was named the "Hertz" in his honor.

In 1864 Scottish mathematical physicist James Clerk Maxwell proposed a comprehensive theory of electromagnetism, now called Maxwell's equations. Maxwell's theory predicted that coupled electric and magnetic fields could travel through space as an "electromagnetic wave". Maxwell proposed that light consisted of electromagnetic waves of short wavelength, but no one had been able to prove this, or generate or detect electromagnetic waves of other wavelengths.

During Hertz's studies in 1879 Helmholtz suggested that Hertz's doctoral dissertation be on testing Maxwell's theory. Helmholtz had also proposed the "Berlin Prize" problem that year at the Prussian Academy of Sciences for anyone who could experimentally prove an electromagnetic effect in the polarization and depolarization of insulators, something predicted by Maxwell's theory.  Helmholtz was sure Hertz was the most likely candidate to win it. Not seeing any way to build an apparatus to experimentally test this, Hertz thought it was too difficult, and worked on electromagnetic induction instead. Hertz did produce an analysis of Maxwell's equations during his time at Kiel, showing they did have more validity than the then prevalent "action at a distance" theories.

After Hertz received his professorship at Karlsruhe he was experimenting with a pair of Riess spirals in the autumn of 1886 when he noticed that discharging a Leyden jar into one of these coils would produce a spark in the other coil. With an idea on how to build an apparatus, Hertz now had a way to proceed with the "Berlin Prize" problem of 1879 on proving Maxwell's theory (although the actual prize had expired uncollected in 1882).  He used a Ruhmkorff coil-driven spark gap and one-meter wire pair as a radiator. Capacity spheres were present at the ends for circuit resonance adjustments. His receiver was a simple half-wave dipole antenna with a micrometer spark gap between the elements. This experiment produced and received what are now called radio waves in the very high frequency range.

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

1848 – Karl Marx and Friedrich Engels publish The Communist Manifesto.

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

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

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

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

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

Friedrich Engels (28 November 1820 – 5 August 1895) was a German philosopher, historian, communist, social scientist, sociologist, journalist and businessman. His father was an owner of large textile factories in Salford, England, and Barmen, Prussia (now Wuppertal, Germany).

Engels developed what is now known as Marxist theory together with Karl Marx and in 1845 he published The Condition of the Working Class in England, based on personal observations and research in English cities. In 1848, Engels co-authored The Communist Manifesto with Marx and also authored and co-authored (primarily with Marx) many other works. Later, Engels supported Marx financially, allowing him to do research and write Das Kapital. After Marx's death, Engels edited the second and third volumes of Das Kapital. Additionally, Engels organised Marx's notes on the Theories of Surplus Value, which were later published as the "fourth volume" of Das Kapital. In 1884, he published The Origin of the Family, Private Property and the State on the basis of Marx's ethnographic research.

Engels died in London on 5 August 1895, at the age of 74 of laryngeal cancer and following cremation his ashes were scattered off Beachy Head, near Eastbourne.

1885 – The newly completed Washington Monument is dedicated.

The Washington Monument is an obelisk within the National Mall in Washington, D.C., built to commemorate George Washington, once commander-in-chief of the Continental Army (1775–1784) in the American Revolutionary War and the first President of the United States (1789–1797). Located almost due east of the Reflecting Pool and the Lincoln Memorial, the monument, made of marble, granite, and bluestone gneiss, is both the world's tallest predominantly stone structure and the world's tallest obelisk, standing 554 feet 7 11⁄32 inches (169.046 m) tall according to the U.S. National Geodetic Survey (measured 2013–14) or 555 feet 5 1⁄8 inches (169.294 m) tall according to the National Park Service (measured 1884). It is the tallest monumental column in the world if all are measured above their pedestrian entrances. Overtaking the Cologne Cathedral, it was the tallest structure in the world between 1884 and 1889, after which it was overtaken by the Eiffel Tower in Paris.

Construction of the monument began in 1848 and was halted for a period of 23 years, from 1854 to 1877 due to a lack of funds, a struggle for control over the Washington National Monument Society, and the American Civil War. Although the stone structure was completed in 1884, internal ironwork, the knoll, and installation of memorial stones were not completed until 1888. A difference in shading of the marble, visible approximately 150 feet (46 m) or 27% up, shows where construction was halted and later resumed with marble from a different source. The original design was by Robert Mills (1781–1855) of South Carolina, but he did not include his proposed colonnade due to a lack of funds, proceeding only with a bare obelisk. The cornerstone was laid on July 4, 1848; the first stone was laid atop the unfinished stump on August 7, 1880; the capstone was set on December 6, 1884; the completed monument was dedicated on February 21, 1885; and officially opened October 9, 1888.

The Washington Monument is a hollow Egyptian style stone obelisk with a 500-foot (152.4 m) tall column surmounted by a 55-foot (16.8 m) tall pyramidion. Its walls are 15 feet (4.6 m) thick at its base and 1 1⁄2 feet (0.46 m) thick at their top. The marble pyramidion has thin walls only 7 inches (18 cm) thick supported by six arches, two between opposite walls that cross at the center of the pyramidion and four smaller corner arches. The top of the pyramidion is a large marble capstone with a small aluminum pyramid at its apex with inscriptions on all four sides. The lowest 150 feet (45.7 m) of the walls, constructed during the first phase 1848–1854, are composed of a pile of bluestone gneiss rubble stones (not finished stones) held together by a large amount of mortar with a facade of semi-finished marble stones about 1 1⁄4 feet (0.4 m) thick. The upper 350 feet (106.7 m) of the walls, constructed during the second phase 1880–1884, are composed of finished marble surface stones, half of which project into the walls, partially backed by finished granite stones.

The interior is occupied by iron stairs that spiral up the walls, with an elevator in the center, each supported by four iron columns, which do not support the stone structure. The stairs contain fifty sections, most on the north and south walls, with many long landings stretching between them along the east and west walls. These landings allowed many inscribed memorial stones of various materials and sizes to be easily viewed while the stairs were accessible (until 1976), plus one memorial stone between stairs that is difficult to view. The pyramidion has eight observation windows, two per side, and eight red aircraft warning lights, two per side. Two aluminum lightning rods connected via the elevator support columns to ground water protect the monument. The monument's present foundation is 37 feet (11.3 m) thick, consisting of half of its original bluestone gneiss rubble encased in concrete. At the northeast corner of the foundation, 21 feet (6.4 m) below ground, is the marble cornerstone, including a zinc case filled with memorabilia. Fifty American flags fly on a large circle of poles centered on the monument. In 2001, a temporary screening facility was added to the entrance to prevent a terrorist attack. An earthquake in 2011 slightly damaged the monument, and it was closed until 2014. It was closed again for elevator system repairs, security upgrades, and mitigation of soil contamination from August 2016 to September 2019.

1921 – Rezā Shāh takes control of Tehran during a successful coup.

Reza Shah Pahlavi (15 March 1878 – 26 July 1944), commonly known as Reza Shah, was the Shah of Iran from 15 December 1925 until he was forced to abdicate by the Anglo-Soviet invasion of Iran on 16 September 1941.

Two years after the 1921 Persian coup d'état, led by Zia'eddin Tabatabaee, Reza Pahlavi became Iran's prime minister. The appointment was backed by the compliant national assembly of Iran. In 1925 Reza Pahlavi was appointed as the legal monarch of Iran by decision of Iran's constituent assembly. The assembly deposed Ahmad Shah Qajar, the last Shah of the Qajar dynasty, and amended Iran’s 1906 constitution to allow selection of Reza Pahlavi. He founded the Pahlavi dynasty that lasted until overthrown in 1979 during the Iranian Revolution. Reza Shah introduced many social, economic, and political reforms during his reign, ultimately laying the foundation of the modern Iranian state.

His legacy remains controversial to this day. His defenders assert that he was an essential modernizing force for Iran (whose international prominence had sharply declined during Qajar rule), while his detractors assert that his reign was often despotic, with his failure to modernize Iran's large peasant population eventually sowing the seeds for the Iranian Revolution nearly four decades later, which ended 2,500 years of Persian monarchy. Moreover, his insistence on ethnic nationalism and cultural unitarism, along with forced detribalization and sedentarization, resulted in the suppression of several ethnic and social groups. Albeit he was himself of Mazandarani descent, his government carried out an extensive policy of Persianization trying to create a single, united and largely homogeneous nation, similar to Atatürk's policy of Turkification.

1965 Died: Malcolm X, American minister and activist (b. 1925; assassinated)

Malcolm X (born Malcolm Little; May 19, 1925 – February 21, 1965) was an African American Muslim minister and human rights activist who was a popular figure during the civil rights movement. He is best known for his time spent as a vocal spokesman for the Nation of Islam.

Malcolm spent his adolescence living in a series of foster homes or with relatives after his father's death and his mother's hospitalization. He engaged in several illicit activities, eventually being sentenced to 10 years in prison in 1946 for larceny and breaking and entering. In prison, he joined the Nation of Islam, adopted the name Malcolm X (to symbolize his unknown African ancestral surname), and quickly became one of the organization's most influential leaders after being paroled in 1952. Malcolm X then served as the public face of the organization for a dozen years, where he advocated for black empowerment, black supremacy, and the separation of black and white Americans, and publicly criticized the mainstream civil rights movement for its emphasis on nonviolence and racial integration. Malcolm X also expressed pride in some of the Nation's social welfare achievements, namely its free drug rehabilitation program. Throughout his life beginning in the 1950s, Malcolm X endured surveillance from the Federal Bureau of Investigation (FBI) for the Nation's supposed links to communism.

In the 1960s, Malcolm X began to grow disillusioned with the Nation of Islam, as well as with its leader Elijah Muhammad. He subsequently embraced Sunni Islam and the civil rights movement after completing the Hajj to Mecca, and became known as el-Hajj Malik el-Shabazz. After a brief period of travel across Africa, he publicly renounced the Nation of Islam and founded the Islamic Muslim Mosque, Inc. (MMI) and the Pan-African Organization of Afro-American Unity (OAAU). Throughout 1964, his conflict with the Nation of Islam intensified, and he was repeatedly sent death threats. On February 21, 1965, he was assassinated in New York City. Three Nation members were charged with the murder and given indeterminate life sentences. Speculation about the assassination and whether it was conceived or aided by leading or additional members of the Nation, or with law enforcement agencies, have persisted for decades after the shooting.

A controversial figure accused of preaching racism and violence, Malcolm X is also a widely celebrated figure within African-American and Muslim American communities for his pursuit of racial justice. He was posthumously honored with Malcolm X Day, on which he is commemorated in various cities across the United States. Hundreds of streets and schools in the U.S. have been renamed in his honor, while the Audubon Ballroom, the site of his assassination, was partly redeveloped in 2005 to accommodate the Malcolm X and Dr. Betty Shabazz Memorial and Educational Center.

Here are some events that happened on February 20th. It could be an event or a person that died or was born on that day

1819 Born: Alfred Escher, Swiss businessman and politician (d. 1882)

Johann Heinrich Alfred Escher vom Glas, known as Alfred Escher (20 February 1819 – 6 December 1882) was a Swiss politician, business leader and railways pioneer. Thanks to his numerous political posts and his significant role in the foundation and management of the Swiss Northeastern Railway, the Swiss Federal Institute of Technology, Credit Suisse, Swiss Life and the Gotthard Railway, Escher had an unmatched influence on Switzerland's political and economic development in the 19th century.

1902 Born: Ansel Adams, American photographer and environmentalist (d. 1984)

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.

1907 Died: Henri Moissan, French chemist and academic, Nobel Prize laureate (b. 1852)

Ferdinand Frédéric Henri Moissan (28 September 1852 – 20 February 1907) was a French chemist and pharmacist who won the 1906 Nobel Prize in Chemistry for his work in isolating fluorine from its compounds. Moissan was one of the original members of the International Atomic Weights Committee.

Moissan was born in Paris on 28 September 1852, the son of a minor officer of the eastern railway company, Francis Ferdinand Moissan, and a seamstress, Joséphine Améraldine (née Mitel). His mother was of Jewish descent, his father wasn't. In 1864 they moved to Meaux, where he attended the local school. In 1870 he left the school without the grade universitaire necessary to attend university. Moissan became a trainee in pharmacy in 1871 and in 1872 he started working for a chemist in Paris, where he was able to save a person poisoned with arsenic. He decided to study chemistry and began first at the laboratory of Edmond Frémy and later at that of Pierre Paul Dehérain. Dehérain persuaded him to pursue an academic career. He passed the baccalauréat, which was necessary to study at university, in 1874 after an earlier failed attempt. He also became qualified as first-class pharmacist at the École Supérieure de Pharmacie in 1879, and received his doctoral degree from the Faculté des Sciences in 1880. During his time in Paris he became a friend of the chemist Alexandre Léon Étard and the botanist Vasque.

He published his first scientific paper, about carbon dioxide and oxygen metabolism in plants, with Dehérain in 1874. He left plant physiology and then turned towards inorganic chemistry; subsequently his research on pyrophoric iron was well received by the two most prominent French inorganic chemists of that time, Henri Etienne Sainte-Claire Deville and Jules Henri Debray. After Moissan received his Ph.D. on cyanogen and its reactions to form cyanures in 1880, his friend Landrine offered him a position at an analytic laboratory. His marriage, to Léonie Lugan, took place in 1882. They had a son in 1885.

During the 1880s, Moissan focused on fluorine chemistry and especially the production of fluorine itself. He had no laboratory of his own, but used several laboratories, for example that of Charles Friedel. There he had access to a strong battery consisting of 90 Bunsen cells which made it possible to observe a gas produced by the electrolysis of molten arsenic trichloride; the gas was reabsorbed by the arsenic trichloride. The electrolysis of hydrogen fluoride yielded fluorine on 26 June 1886. The French academy of science sent three representatives, Marcellin Berthelot, Henri Debray, and Edmond Frémy, to verify the results, but Moissan was unable to reproduce them, owing to the absence from the hydrogen fluoride of traces of potassium fluoride present in the previous experiments. After resolving the problem and demonstrating the production of fluorine several times, he was awarded a prize of 10,000 francs. In subsequent years, until 1891, he focused on the study of fluorine chemistry. He discovered numerous fluorine compounds, such as (together with Paul Lebeau) SF6 in 1901. His research in the production of boron and artificial diamonds and the development of an electrically heated oven capable of reaching 3500 °C using 2200 amperes at 80 volts followed by 1900.

His newly developed arc furnace led to the production of borides and carbides of numerous elements (e.g. silicon boride), another of his research areas.

1936 Died: Max Schreck, German actor (b. 1879)

Friedrich Gustav Maximilian Schreck (6 September 1879 – 20 February 1936), known professionally as Max Schreck, was a German actor, best known for his lead role as the vampire Count Orlok in the film Nosferatu (1922)

Nosferatu: A Symphony of Horror (German: Nosferatu, eine Symphonie des Grauens), or simply Nosferatu, is a 1922 German Expressionist horror film, directed by F. W. Murnau, starring Max Schreck as the vampire Count Orlok. The film, shot in 1921 and released in 1922, was an unauthorized adaptation of Bram Stoker's Dracula (1897); the Stoker Estate had refused permission. Various names and other details were changed from the novel: for instance, vampire became Nosferatu, and Count Dracula became Count Orlok.

Stoker's heirs sued over the adaptation, and a court ruling ordered that all copies of the film be destroyed. However, a few prints of Nosferatu survived, and the film came to be regarded as an influential masterpiece of cinema.

The film was released in the United States on 3 June 1929, seven years after its original premiere in Germany.

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

1473 Born: Nicolaus Copernicus, Polish mathematician and astronomer (d. 1543)

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

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

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

1833 Born: Élie Ducommun, Swiss journalist and educator, Nobel Prize laureate (d. 1906)

Élie Ducommun (19 February 1833, Geneva – 7 December 1906, Bern) was a Swiss peace activist. He was a Nobel laureate, awarded the 1902 Nobel Peace Prize, which he shared with Charles Albert Gobat.

Born in Geneva, he worked as a tutor, language teacher, journalist and a translator for the Swiss federal Chancellery (1869–1873).

In 1867 he helped to found the Ligue de la paix et de la liberté (League of Peace and Freedom), though he continued working at other positions, including secretary for the Jura-Simplon Steel Company from 1873 to 1891. That year, he was appointed director of the newly formed Bureau international de la paix (International Peace Office), the first non-governmental international peace organization, based in Bern. He refused to accept a salary for the position, stating that he wished to serve in this capacity solely for reasons of idealism.

His keen organizational skills ensured the group's success. He was awarded in the Nobel Peace Prize in 1902, and served as director of the organization until his death in 1906.

1859 Born: Svante Arrhenius, Swedish physicist and chemist, Nobel Prize laureate (d. 1927)

Svante August Arrhenius (19 February 1859 – 2 October 1927) was a Swedish scientist. Originally a physicist, but often referred to as a chemist, Arrhenius was one of the founders of the science of physical chemistry. He received the Nobel Prize for Chemistry in 1903, becoming the first Swedish Nobel laureate. In 1905, he became director of the Nobel Institute, where he remained until his death.

Arrhenius was the first to use principles of physical chemistry to estimate the extent to which increases in atmospheric carbon dioxide are responsible for the Earth's increasing surface temperature. In the 1960s, Charles David Keeling demonstrated that the quantity of human-caused carbon dioxide emissions into the air is enough to cause global warming.

The Arrhenius equation, Arrhenius acid, Arrhenius base, lunar crater Arrhenius, Martian crater Arrhenius, the mountain of Arrheniusfjellet, and the Arrhenius Labs at Stockholm University were so named to commemorate his contributions to science.

1878 – Thomas Edison patents the phonograph.

Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman who has been described as America's greatest inventor. He developed many devices in fields such as electric power generation, mass communication, sound recording, and motion pictures. These inventions, which include the phonograph, the motion picture camera, and early versions of the electric light bulb, have had a widespread impact on the modern industrialized world. He was one of the first inventors to apply the principles of organized science and teamwork to the process of invention, working with many researchers and employees. He established the first industrial research laboratory.

Edison was raised in the American Midwest; early in his career he worked as a telegraph operator, which inspired some of his earliest inventions. In 1876, he established his first laboratory facility in Menlo Park, New Jersey, where many of his early inventions were developed. He later established a botanic laboratory in Fort Myers, Florida in collaboration with businessmen Henry Ford and Harvey S. Firestone, and a laboratory in West Orange, New Jersey that featured the world's first film studio, the Black Maria. He was a prolific inventor, holding 1,093 US patents in his name, as well as patents in other countries. Edison married twice and fathered six children. He died in 1931 of complications of diabetes.

1887 Died: Multatuli, Dutch-German author and civil servant (b. 1820)

Eduard Douwes Dekker (2 March 1820 – 19 February 1887), better known by his pen name Multatuli (from Latin multa tulī, "I have suffered much"), was a Dutch writer best known for his satirical novel Max Havelaar (1860), which denounced the abuses of colonialism in the Dutch East Indies (today's Indonesia). He is considered one of the Netherlands' greatest authors.

Determined to expose the scandals he had witnessed during his years in the Dutch East Indies, Douwes Dekker began to write newspaper articles and pamphlets. Little notice was taken of these early publications until, in 1860, he published his satirical anticolonialist novel Max Havelaar: The Coffee Auctions of the Dutch Trading Company under the pseudonym Multatuli. Douwes Dekker's pen name is derived from the Latin phrase multa tuli, meaning "I have suffered much" (or more literally: "I have borne much"). It refers both to himself and to the victims of the injustices he saw.

Douwes Dekker was one of Sigmund Freud's favorite writers; his name heads a list of 'ten good books' that Freud drew up in 1907. Several other writers from different generations were appreciative of Multatuli, like Marx, Anatole France, Hermann Hesse, Willem Elsschot, Thomas and Heinrich Mann, and most of the first-wave feminists.

In June 2002, the Dutch Maatschappij der Nederlandse Letterkunde (Society of Dutch Literature) proclaimed Multatuli the most important Dutch writer of all time.
The annual Multatuli Prize, a Dutch literary prize, is named in his honor. The literary award Woutertje Pieterse Prijs is named after the character Woutertje Pieterse in Multatuli's De geschiedenis van Woutertje Pieterse.

The Mutatuli Museum is located in Amsterdam at Korsjespoortsteeg 20, where Eduard Douwes Dekker was born.
