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

1676 – The Danish astronomer Ole Rømer presents the first quantitative measurements of the speed of light.

Ole Christensen Rømer (25 September 1644 – 19 September 1710) was a Danish astronomer who, in 1676, made the first quantitative measurements of the speed of light.

Rømer also invented the modern thermometer showing the temperature between two fixed points, namely the points at which water respectively boils and freezes.

In addition to inventing the first street lights in Copenhagen, Rømer also invented the meridian circle, the altazimuth, and the passage instrument (also known as the transit instrument, a type of meridian circle whose horizontal axis is not fixed in the east-west direction).

In scientific literature, alternative spellings such as "Roemer", "Römer", or "Romer" are common.

1694 Born: Voltaire, French philosopher and author (d. 1778)

François-Marie Arouet (21 November 1694 – 30 May 1778), known by his nom de plume Voltaire , was a French Enlightenment writer, historian, and philosopher famous for his wit, his criticism of Christianity—especially the Roman Catholic Church—as well as his advocacy of freedom of speech, freedom of religion, and separation of church and state.

Voltaire was a versatile and prolific writer, producing works in almost every literary form, including plays, poems, novels, essays, histories, and scientific expositions. He wrote more than 20,000 letters and 2,000 books and pamphlets. He was one of the first authors to become renowned and commercially successful internationally. He was an outspoken advocate of civil liberties, and he was at constant risk from the strict censorship laws of the Catholic French monarchy. His polemics witheringly satirized intolerance, religious dogma, and the French institutions of his day.

François-Marie Arouet was born in Paris, the youngest of the five children of François Arouet (1649–1722), a lawyer who was a minor treasury official, and his wife, Marie Marguerite Daumard (c. 1660–1701), whose family was on the lowest rank of the French nobility. Some speculation surrounds Voltaire's date of birth, because he claimed he was born on 20 February 1694 as the illegitimate son of a nobleman, Guérin de Rochebrune or Roquebrune. Two of his older brothers—Armand-François and Robert—died in infancy, and his surviving brother Armand and sister Marguerite-Catherine were nine and seven years older, respectively. Nicknamed "Zozo" by his family, Voltaire was baptized on 22 November 1694, with François de Castagnère, abbé de Châteauneuf, and Marie Daumard, the wife of his mother's cousin, standing as godparents. He was educated by the Jesuits at the Collège Louis-le-Grand (1704–1711), where he was taught Latin, theology, and rhetoric; later in life he became fluent in Italian, Spanish, and English.

By the time he left school, Voltaire had decided he wanted to be a writer, against the wishes of his father, who wanted him to become a lawyer. Voltaire, pretending to work in Paris as an assistant to a notary, spent much of his time writing poetry. When his father found out, he sent Voltaire to study law, this time in Caen, Normandy. But the young man continued to write, producing essays and historical studies. Voltaire's wit made him popular among some of the aristocratic families with whom he mixed. In 1713, his father obtained a job for him as a secretary to the new French ambassador in the Netherlands, the marquis de Châteauneuf, the brother of Voltaire's godfather. At The Hague, Voltaire fell in love with a French Protestant refugee named Catherine Olympe Dunoyer (known as 'Pimpette'). Their affair, considered scandalous, was discovered by de Châteauneuf and Voltaire was forced to return to France by the end of the year.

Voltaire was imprisoned in the Bastille from 16 May 1717 to 15 April 1718 in a windowless cell with ten-foot-thick walls.

Most of Voltaire's early life revolved around Paris. From early on, Voltaire had trouble with the authorities for critiques of the government. As a result, he was twice sentenced to prison and once to temporary exile to England. One satirical verse, in which Voltaire accused the Régent of incest with his daughter, resulted in an eleven-month imprisonment in the Bastille. The Comédie-Française had agreed in January 1717 to stage his debut play, Œdipe, and it opened in mid-November 1718, seven months after his release. Its immediate critical and financial success established his reputation. Both the Régent and King George I of Great Britain presented Voltaire with medals as a mark of their appreciation.

He mainly argued for religious tolerance and freedom of thought. He campaigned to eradicate priestly and aristo-monarchical authority, and supported a constitutional monarchy that protects people's rights.

Voltaire's best-known histories are History of Charles XII (1731), The Age of Louis XIV (1751), and his Essay on the Customs and the Spirit of the Nations (1756). He broke from the tradition of narrating diplomatic and military events, and emphasized customs, social history and achievements in the arts and sciences. The Essay on Customs traced the progress of world civilization in a universal context, rejecting both nationalism and the traditional Christian frame of reference. Influenced by Bossuet's Discourse on Universal History (1682), he was the first scholar to attempt seriously a history of the world, eliminating theological frameworks, and emphasizing economics, culture and political history. He treated Europe as a whole rather than a collection of nations. He was the first to emphasize the debt of medieval culture to Middle Eastern civilization, but otherwise was weak on the Middle Ages. Although he repeatedly warned against political bias on the part of the historian, he did not miss many opportunities to expose the intolerance and frauds of the church over the ages. Voltaire advised scholars that anything contradicting the normal course of nature was not to be believed. Although he found evil in the historical record, he fervently believed reason and expanding literacy would lead to progress.

Voltaire explains his view of historiography in his article on "History" in Diderot's Encyclopédie: "One demands of modern historians more details, better ascertained facts, precise dates, more attention to customs, laws, mores, commerce, finance, agriculture, population." Voltaire's histories imposed the values of the Enlightenment on the past, but at the same time he helped free historiography from antiquarianism, Eurocentrism, religious intolerance and a concentration on great men, diplomacy, and warfare. Yale professor Peter Gay says Voltaire wrote "very good history", citing his "scrupulous concern for truths", "careful sifting of evidence", "intelligent selection of what is important", "keen sense of drama", and "grasp of the fact that a whole civilization is a unit of study"

From an early age, Voltaire displayed a talent for writing verse, and his first published work was poetry. He wrote two book-long epic poems, including the first ever written in French, the Henriade, and later, The Maid of Orleans, besides many other smaller pieces.

The Henriade was written in imitation of Virgil, using the alexandrine couplet reformed and rendered monotonous for modern readers but it was a huge success in the 18th and early 19th century, with sixty-five editions and translations into several languages. The epic poem transformed French King Henry IV into a national hero for his attempts at instituting tolerance with his Edict of Nantes. La Pucelle, on the other hand, is a burlesque on the legend of Joan of Arc.

1789 – North Carolina ratifies the United States Constitution and is admitted as the 12th U.S. state.

North Carolina is a state in the southeastern region of the United States. North Carolina is the 28th largest and 9th-most populous of the 50 United States. It is bordered by Virginia to the north, the Atlantic Ocean to the east, Georgia and South Carolina to the south, and Tennessee to the west. Raleigh is the state's capital and Charlotte is its largest city. The Charlotte metropolitan area, with an estimated population of 2,569,213 in 2018, is the most-populous metropolitan area in North Carolina, the 23rd-most populous in the United States, and the largest banking center in the nation after New York City. The Raleigh metropolitan area is the second-largest metropolitan area in the state, with an estimated population of 1,362,540 in 2018, and is home to the largest research park in the United States, Research Triangle Park.

North Carolina was established as a royal colony in 1729 and is one of the original Thirteen Colonies. North Carolina is named in honor of King Charles I of England who first formed the English colony, Carolus being Latin for "Charles". On November 21, 1789, North Carolina became the 12th state to ratify the United States Constitution. In the run-up to the American Civil War, North Carolina declared its secession from the Union on May 20, 1861, becoming the last of eleven states to join the Confederate States. Following the Civil War, the state was restored to the Union on June 25, 1868. On December 17, 1903, Orville and Wilbur Wright successfully piloted the world's first controlled, sustained flight of a powered, heavier-than-air aircraft at Kill Devil Hills in North Carolina's Outer Banks. North Carolina uses the slogan "First in Flight" on state license plates to commemorate this achievement, alongside a newer alternative design bearing the slogan "First in Freedom" in reference to the Mecklenburg Declaration.

North Carolina is defined by a wide range of elevations and landscapes. From west to east, North Carolina's elevation descends from the Appalachian Mountains to the Piedmont and Atlantic coastal plain. North Carolina's Mount Mitchell at 6,684 feet (2,037 m) is the highest-point in North America east of the Mississippi River. Most of the state falls in the humid subtropical climate zone; however, the western, mountainous part of the state has a subtropical highland climate.

1905 – Albert Einstein's paper that leads to the mass–energy equivalence formula, E = mc², is published in the journal Annalen der Physik.

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

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

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

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

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

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

1916 Died: Franz Joseph I of Austria (b. 1830)

Franz Joseph I or Francis Joseph I (German: Franz Joseph I.; 18 August 1830 – 21 November 1916) was Emperor of Austria, King of Hungary, King of Bohemia, and monarch of many other states of the Austro-Hungarian Empire, from 2 December 1848 to his death. From 1 May 1850 to 24 August 1866 he was also President of the German Confederation. He was the longest-reigning Emperor of Austria and King of Hungary, as well as the third-longest-reigning monarch of any country in European history, after Louis XIV of France and Johann II of Liechtenstein.

In December 1848, Emperor Ferdinand abdicated the throne at Olomouc, as part of Minister President Felix zu Schwarzenberg's plan to end the Revolutions of 1848 in Hungary. This allowed Ferdinand's nephew Franz Joseph to accede to the throne. Largely considered to be a reactionary, Franz Joseph spent his early reign resisting constitutionalism in his domains. The Austrian Empire was forced to cede its influence over Tuscany and most of its claim to Lombardy–Venetia to the Kingdom of Piedmont-Sardinia, following the Second Italian War of Independence in 1859 and the Third Italian War of Independence in 1866. Although Franz Joseph ceded no territory to the Kingdom of Prussia after the Austrian defeat in the Austro-Prussian War, the Peace of Prague (23 August 1866) settled the German Question in favour of Prussia, which prevented the Unification of Germany from occurring under the House of Habsburg.

Franz Joseph was troubled by nationalism during his entire reign. He concluded the Austro-Hungarian Compromise of 1867, which granted greater autonomy to Hungary and transformed the Austrian Empire into the Dual Monarchy of Austria-Hungary. He ruled peacefully for the next 45 years, but personally suffered the tragedies of the execution of his brother, the Emperor Maximilian of Mexico in 1867, the suicide of his only son and heir-apparent, Crown Prince Rudolf, in 1889, the assassination of his wife, Empress Elisabeth, in 1898, and the assassination of his nephew and heir-presumptive, the Archduke Franz Ferdinand, in 1914.

After the Austro-Prussian War, Austria-Hungary turned its attention to the Balkans, which was a hotspot of international tension because of conflicting interests with the Russian Empire. The Bosnian Crisis was a result of Franz Joseph's annexation of Bosnia and Herzegovina in 1908, which had been occupied by his troops since the Congress of Berlin (1878).

On 28 June 1914, the assassination of his nephew and heir-presumptive, Archduke Franz Ferdinand, in Sarajevo resulted in Austria-Hungary's declaration of war against the Kingdom of Serbia, which was an ally of the Russian Empire. That activated a system of alliances which resulted in World War I.

Franz Joseph died on 21 November 1916, after ruling his domains for almost 68 years as one of the longest-reigning monarchs in modern history. He was succeeded by his grandnephew Charles.

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

1632 Born: Antonie van Leeuwenhoek, Dutch biologist and microbiologist (d. 1723)

Antonie Philips van Leeuwenhoek (24 October 1632 – 26 August 1723) was a Dutch businessman and scientist in the Golden Age of Dutch science and technology. A largely self-taught man in science, he is commonly known as "the Father of Microbiology", and one of the first microscopists and microbiologists. Van Leeuwenhoek is best known for his pioneering work in microscopy and for his contributions toward the establishment of microbiology as a scientific discipline.

Raised in Delft, Dutch Republic, van Leeuwenhoek worked as a draper in his youth and founded his own shop in 1654. He became well recognized in municipal politics and developed an interest in lensmaking. In the 1670s, he started to explore microbial life with his microscope.  This was one of the notable achievements of the Golden Age of Dutch exploration and discovery (c. 1590s–1720s).

Using single-lensed microscopes of his own design, van Leeuwenhoek was the first to experiment with microbes, which he originally referred to as dierkens, diertgens or diertjes (Dutch for "small animals" [translated into English as animalcules, from Latin animalculum = "tiny animal"]). Through his experiments, he was the first to relatively determine their size. Most of the "animalcules" are now referred to as unicellular organisms, although he observed multicellular organisms in pond water. He was also the first to document microscopic observations of muscle fibers, bacteria, spermatozoa, red blood cells, crystals in gouty tophi, and blood flow in capillaries. Although van Leeuwenhoek did not write any books, his discoveries came to light through correspondence with the Royal Society, which published his letters.

1799 Died: Carl Ditters von Dittersdorf, Austrian violinist and composer (b. 1739)

Carl Ditters von Dittersdorf (2 November 1739 – 24 October 1799) was an Austrian composer, violinist and silvologist.

Dittersdorf was born in the Laimgrube (now Mariahilf) district of Vienna, Austria, as August Carl Ditters. His father was a military tailor in the Austrian Imperial Army of Charles VI, for a number of German-speaking regiments. After retiring honorably from his military obligation, he was provided with royal letters of reference and a sinecure with the Imperial Theatre. In 1745, the six-year-old August Carl was introduced to the violin and his father's moderate financial position allowed him not only a good general education at a Jesuit school, but private tutelage in music, violin, French and religion. After leaving his first teacher, Carl studied violin with J. Ziegler, who by 1750, through his influence, secured his pupil's appointment as a violinist in the orchestra of the Benedictine church on the Freyung.

Ditters' early work laid the groundwork for his later more important compositions. His symphonic and chamber compositions greatly emphasize sensuous Italo-Austrian melody instead of motivic development, which is often entirely lacking even in his best works, quite unlike those of his greater peers Haydn and Mozart.

Even with these reservations, Dittersdorf was an important composer of the Classical era. After some early Italian opere buffe, he turned to writing German Singspiele instead, with Der Apotheker und der Doktor (1786, generally known today as Doktor und Apotheker) in particular being a tremendous success in his lifetime, playing in houses all over Europe and recorded almost two centuries later. Among his 120-or-so symphonies are twelve programmatic ones based on Ovid's Metamorphoses, although only six have survived (and have also been recorded). He also wrote oratorios, cantatas and concertos (among which are two for double bass and one for viola), string quartets and other chamber music, piano pieces and other miscellaneous works. His memoirs, Lebenbeschreibung ("Description of [My] Life"), were published in Leipzig in 1801. Some of his compositions, including the double bass concerto, were published in Leipzig by the Friedrich Hofmeister Musikverlag.

1911 – Orville Wright remains in the air nine minutes and 45 seconds in a glider at Kill Devil Hills, North Carolina.

The Wright brothers—Orville (August 19, 1871 – January 30, 1948) and Wilbur (April 16, 1867 – May 30, 1912)—were two American aviation pioneers generally credited with inventing, building, and flying the world's first successful motor-operated airplane. They made the first controlled, sustained flight of a powered, heavier-than-air aircraft with the Wright Flyer on December 17, 1903, 4 mi (6 km) south of Kitty Hawk, North Carolina. In 1904–05, the brothers developed their flying machine to make longer-running and more aerodynamic flights with the Wright Flyer II, followed by the first truly practical fixed-wing aircraft, the Wright Flyer III. The Wright brothers were also the first to invent aircraft controls that made fixed-wing powered flight possible.

The brothers' breakthrough was their creation of a three-axis control system, which enabled the pilot to steer the aircraft effectively and to maintain its equilibrium. This method remains standard on fixed-wing aircraft of all kinds.  From the beginning of their aeronautical work, the Wright brothers focused on developing a reliable method of pilot control as the key to solving "the flying problem". This approach differed significantly from other experimenters of the time who put more emphasis on developing powerful engines. Using a small home-built wind tunnel, the Wrights also collected more accurate data than any before, enabling them to design more efficient wings and propellers.  Their first U.S. patent did not claim invention of a flying machine, but a system of aerodynamic control that manipulated a flying machine's surfaces. 

The brothers gained the mechanical skills essential to their success by working for years in their Dayton, Ohio-based shop with printing presses, bicycles, motors, and other machinery. Their work with bicycles, in particular, influenced their belief that an unstable vehicle such as a flying machine could be controlled and balanced with practice. From 1900 until their first powered flights in late 1903, they conducted extensive glider tests that also developed their skills as pilots. Their shop employee Charlie Taylor became an important part of the team, building their first airplane engine in close collaboration with the brothers.

The Wright brothers' status as inventors of the airplane has been subject to counter-claims by various parties. Much controversy persists over the many competing claims of early aviators. Edward Roach, historian for the Dayton Aviation Heritage National Historical Park, argues that they were excellent self-taught engineers who could run a small company, but they did not have the business skills or temperament to dominate the growing aviation industry.

1926 – Harry Houdini's last performance takes place at the Garrick Theatre in Detroit.

Harry Houdini (born Erik Weisz, later Ehrich Weiss or Harry Weiss; March 24, 1874 – October 31, 1926) was a Hungarian-born American illusionist and stunt performer, noted for his sensational escape acts. He first attracted notice in vaudeville in the United States and then as "Harry 'Handcuff' Houdini" on a tour of Europe, where he challenged police forces to keep him locked up. Soon he extended his repertoire to include chains, ropes slung from skyscrapers, straitjackets under water, and having to escape from and hold his breath inside a sealed milk can with water in it.

In 1904, thousands watched as he tried to escape from special handcuffs commissioned by London's Daily Mirror, keeping them in suspense for an hour. Another stunt saw him buried alive and only just able to claw himself to the surface, emerging in a state of near-breakdown. While many suspected that these escapes were faked, Houdini presented himself as the scourge of fake spiritualists. As President of the Society of American Magicians, he was keen to uphold professional standards and expose fraudulent artists. He was also quick to sue anyone who imitated his escape stunts.

Houdini made several movies but quit acting when it failed to bring in money. He was also a keen aviator and aimed to become the first man to fly a plane in Australia.

1931 – The George Washington Bridge opens to public traffic over the Hudson River.

The George Washington Bridge is a double-decked suspension bridge spanning the Hudson River, connecting the New York City borough of Manhattan with the New Jersey borough of Fort Lee. The bridge is named after George Washington, the first president of the United States. The George Washington Bridge is the world's busiest motor vehicle bridge, carrying over 103 million vehicles per year in 2016. It is owned by the Port Authority of New York and New Jersey, a bi-state government agency that operates infrastructure in the Port of New York and New Jersey. The George Washington Bridge is also informally known as the GW Bridge, the GWB, the GW, or the George, and was known as the Fort Lee Bridge or Hudson River Bridge during construction.

The idea of a bridge across the Hudson River was first proposed in 1906, but it was not until 1925 that the state legislatures of New York and New Jersey voted to allow for the planning and construction of such a bridge. Construction on the George Washington Bridge started in October 1927; the bridge was ceremonially dedicated on October 24, 1931, and opened to traffic the next day. The opening of the George Washington Bridge contributed to the development of Bergen County, New Jersey, in which Fort Lee is located. The upper deck was widened from six to eight lanes in 1946. The six-lane lower deck was constructed beneath the existing span from 1958 to 1962 because of increasing traffic flow.

The George Washington Bridge is an important travel corridor within the New York metropolitan area. It has an upper level that carries four lanes in each direction and a lower level with three lanes in each direction, for a total of 14 lanes of travel. The speed limit on the bridge is 45 mph (72 km/h). The bridge's upper level also carries pedestrian and bicycle traffic. Interstate 95 (I-95) and U.S. Route 1/9 (US 1/9, composed of US 1 and US 9) cross the river via the bridge. The New Jersey Turnpike (part of I-95) and U.S. Route 46 (US 46), which lie entirely within New Jersey, terminate halfway across the bridge at the state border with New York. At its eastern terminus in New York City, the bridge continues onto the Trans-Manhattan Expressway (part of I-95, connecting to the Cross Bronx Expressway).

The George Washington Bridge measures 4,760 feet (1,450 m) long and has a main span of 3,500 feet (1,100 m). It had the longest main bridge span in the world at the time of its opening and held that distinction until the opening of the Golden Gate Bridge in 1937.

1949 – The cornerstone of the United Nations Headquarters is laid.

The United Nations is headquartered in New York City in a complex designed by a board of architects led by Wallace Harrison and built by the architectural firm Harrison & Abramovitz. The complex has served as the official headquarters of the United Nations since its completion in 1952. It is in the Turtle Bay neighborhood of Manhattan, on 17 to 18 acres (6.9 to 7.3 ha) of grounds overlooking the East River. Its borders are First Avenue on the west, East 42nd Street to the south, East 48th Street on the north, and the East River to the east. The term "Turtle Bay" is occasionally used as a metonym for the UN headquarters or for the United Nations as a whole.

The headquarters holds the seats of the principal organs of the UN, including the General Assembly and the Security Council, but excluding the International Court of Justice, which is seated in the Hague. The United Nations has three additional subsidiary regional headquarters, or headquarters districts. These were opened in Geneva (Switzerland) in 1946, Vienna (Austria) in 1980, and Nairobi (Kenya) in 1996. These adjunct offices help represent UN interests, facilitate diplomatic activities, and enjoy certain extraterritorial privileges, but do not contain the seats of major organs.

Although it is in New York City, the land occupied by the United Nations Headquarters and the spaces of buildings that it rents are under the sole administration of the United Nations and not the U.S. government. They are technically extraterritorial through a treaty agreement with the U.S. government. However, in exchange for local police, fire protection, and other services, the United Nations agrees to acknowledge most local, state, and federal laws.

None of the United Nations' 15 specialized agencies (such as UNESCO) are located at the headquarters. However, some "autonomous subsidiary organs", such as UNICEF, have their headquarters at the UNHQ.

Here are some events that happened on October 17th. It could be an event or a person that died or was born on that day

1806 Died: Jean-Jacques Dessalines, Haitian commander and politician, Governor-General of Haiti (b. 1758)

Jean-Jacques Dessalines (Haitian Creole: Jan-Jak Desalin; 20 September 1758 – 17 October 1806) was a leader of the Haitian Revolution and the first ruler of an independent Haiti under the 1805 constitution. Under Dessalines, Haiti became the first country in the Americas to permanently abolish slavery. Initially regarded as governor-general, Dessalines was later named Emperor of Haiti as Jacques I (1804–1806) by generals of the Haitian Revolution Army and ruled in that capacity until being assassinated in 1806. He is regarded as one of the founding fathers of Haiti.

Dessalines served as an officer in the French army, when the colony was fending off Spanish and British incursions. Later he rose to become a commander in the revolt against France. As Toussaint Louverture's principal lieutenant, he led many successful engagements, including the Battle of Crête-à-Pierrot.

After the betrayal and capture of Toussaint Louverture in 1802, Dessalines became the leader of the revolution. He defeated a French army at the Battle of Vertières in 1803. Declaring Haiti an independent nation in 1804, Dessalines was chosen by a council of generals to assume the office of governor-general. He ordered the 1804 Haiti massacre of French settlers in Haiti, resulting in the deaths of between 3,000 and 5,000 people, but declared that the Polish foreign mercenaries who defected from the French Legion could remain in the new country. In September 1804, he was proclaimed emperor by the Generals of the Haitian Revolution Army and ruled in that capacity until being assassinated in 1806.

1849 Died: Frédéric Chopin, Polish pianist and composer (b. 1810)

Frédéric François Chopin, born Fryderyk Franciszek Chopin (1 March 1810 – 17 October 1849), was a Polish composer and virtuoso pianist of the Romantic era who wrote primarily for solo piano. He has maintained worldwide renown as a leading musician of his era, one whose "poetic genius was based on a professional technique that was without equal in his generation."

Chopin was born in Żelazowa Wola in the Duchy of Warsaw and grew up in Warsaw, which in 1815 became part of Congress Poland. A child prodigy, he completed his musical education and composed his earlier works in Warsaw before leaving Poland at the age of 20, less than a month before the outbreak of the November 1830 Uprising. At 21, he settled in Paris. Thereafter—in the last 18 years of his life—he gave only 30 public performances, preferring the more intimate atmosphere of the salon. He supported himself by selling his compositions and by giving piano lessons, for which he was in high demand. Chopin formed a friendship with Franz Liszt and was admired by many of his other musical contemporaries, including Robert Schumann.

After a failed engagement to Maria Wodzińska from 1836 to 1837, he maintained an often troubled relationship with the French writer Amantine Dupin (known by her pen name, George Sand). A brief and unhappy visit to Majorca with Sand in 1838–39 would prove one of his most productive periods of composition. In his final years, he was supported financially by his admirer Jane Stirling, who also arranged for him to visit Scotland in 1848. For most of his life, Chopin was in poor health. He died in Paris in 1849 at the age of 39, probably of pericarditis aggravated by tuberculosis.

All of Chopin's compositions include the piano. Most are for solo piano, though he also wrote two piano concertos, a few chamber pieces, and some 19 songs set to Polish lyrics. His piano writing was technically demanding and expanded the limits of the instrument, his own performances noted for their nuance and sensitivity. His major piano works also include mazurkas, waltzes, nocturnes, polonaises, the instrumental ballade (which Chopin created as an instrumental genre), études, impromptus, scherzos, preludes and sonatas, some published only posthumously. Among the influences on his style of composition were Polish folk music, the classical tradition of J. S. Bach, Mozart, and Schubert, and the atmosphere of the Paris salons of which he was a frequent guest. His innovations in style, harmony, and musical form, and his association of music with nationalism, were influential throughout and after the late Romantic period.

Chopin's music, his status as one of music's earliest celebrities, his indirect association with political insurrection, his high-profile love-life, and his early death have made him a leading symbol of the Romantic era. His works remain popular, and he has been the subject of numerous films and biographies of varying historical fidelity.

1887 Died: Gustav Kirchhoff, German physicist and chemist (b. 1824)

Gustav Robert Kirchhoff (12 March 1824 – 17 October 1887) was a German physicist who contributed to the fundamental understanding of electrical circuits, spectroscopy, and the emission of black-body radiation by heated objects.

He coined the term black-body radiation in 1862. Several different sets of concepts are named "Kirchhoff's laws" after him, concerning such diverse subjects as black-body radiation and spectroscopy, electrical circuits, and thermochemistry. The Bunsen–Kirchhoff Award for spectroscopy is named after him and his colleague, Robert Bunsen.

Here are some events that happened on October 16th. It could be an event or a person that died or was born on that day

1758 Born: Noah Webster, American lexicographer (d. 1843)

Noah Webster Jr. (October 16, 1758 – May 28, 1843) was an American lexicographer, textbook pioneer, English-language spelling reformer, political writer, editor, and prolific author. He has been called the "Father of American Scholarship and Education". His "Blue-backed Speller" books taught five generations of American children how to spell and read. Webster's name has become synonymous with "dictionary" in the United States, especially the modern Merriam-Webster dictionary that was first published in 1828 as An American Dictionary of the English Language.

Born in West Hartford, Connecticut, Webster was graduated from Yale College in 1778. He passed the bar examination after studying law under Oliver Ellsworth and others, but was unable to find work as a lawyer. He found some financial success by opening a private school and writing a series of educational books, including the "Blue-Backed Speller." A strong supporter of the American Revolution and the ratification of the United States Constitution, Webster later criticized American society for being in need of an intellectual foundation. He believed that American nationalism was superior to Europe because American values were superior.

In 1793, Alexander Hamilton recruited Webster to move to New York City and become an editor for a Federalist Party newspaper. He became a prolific author, publishing newspaper articles, political essays, and textbooks. He returned to Connecticut in 1798 and served in the Connecticut House of Representatives. Webster founded the Connecticut Society for the Abolition of Slavery in 1791 but later became somewhat disillusioned with the abolitionist movement.

In 1806, Webster published his first dictionary, A Compendious Dictionary of the English Language. The following year, he started working on an expanded and comprehensive dictionary, finally publishing it in 1828. He was very influential in popularizing certain spellings in the United States. He was also influential in establishing the Copyright Act of 1831, the first major statutory revision of U.S. copyright law. While working on a second volume of his dictionary, Webster died in 1843, and the rights to the dictionary were acquired by George and Charles Merriam.

1803 Born: Robert Stephenson, English railway and civil engineer (d. 1859)

Robert Stephenson (16 October 1803 – 12 October 1859) was an English railway and civil engineer. The only son of George Stephenson, the "Father of Railways", he built on the achievements of his father. Robert has been called the greatest engineer of the 19th century.

1854 Born: Oscar Wilde, Irish playwright, novelist, and poet (d. 1900)

Oscar Fingal O'Flahertie Wills Wilde (16 October 1854 – 30 November 1900) was an Irish poet and playwright. After writing in different forms throughout the 1880s, the early 1890s saw him become one of the most popular playwrights in London. He is best remembered for his epigrams and plays, his novel The Picture of Dorian Gray, and the circumstances of his criminal conviction for gross indecency for consensual homosexual acts, imprisonment, and early death at age 46.

Wilde's parents were Anglo-Irish intellectuals in Dublin. A young Wilde learned to speak fluent French and German. At university, Wilde read Greats; he demonstrated himself to be an exceptional classicist, first at Trinity College Dublin, then at Oxford. He became associated with the emerging philosophy of aestheticism, led by two of his tutors, Walter Pater and John Ruskin. After university, Wilde moved to London into fashionable cultural and social circles.

As a spokesman for aestheticism, he tried his hand at various literary activities: he published a book of poems, lectured in the United States and Canada on the new "English Renaissance in Art" and interior decoration, and then returned to London where he worked prolifically as a journalist. Known for his biting wit, flamboyant dress and glittering conversational skill, Wilde became one of the best-known personalities of his day. At the turn of the 1890s, he refined his ideas about the supremacy of art in a series of dialogues and essays, and incorporated themes of decadence, duplicity, and beauty into what would be his only novel, The Picture of Dorian Gray (1890). The opportunity to construct aesthetic details precisely, and combine them with larger social themes, drew Wilde to write drama. He wrote Salome (1891) in French while in Paris but it was refused a licence for England due to an absolute prohibition on the portrayal of Biblical subjects on the English stage. Unperturbed, Wilde produced four society comedies in the early 1890s, which made him one of the most successful playwrights of late-Victorian London.

At the height of his fame and success, while The Importance of Being Earnest (1895) was still being performed in London, Wilde prosecuted the Marquess of Queensberry for criminal libel. The Marquess was the father of Wilde's lover, Lord Alfred Douglas. The libel trial unearthed evidence that caused Wilde to drop his charges and led to his own arrest and trial for gross indecency with men. After two more trials he was convicted and sentenced to two years' hard labour, the maximum penalty, and was jailed from 1895 to 1897. During his last year in prison, he wrote De Profundis (published posthumously in 1905), a long letter which discusses his spiritual journey through his trials, forming a dark counterpoint to his earlier philosophy of pleasure. On his release, he left immediately for France, never to return to Ireland or Britain. There he wrote his last work, The Ballad of Reading Gaol (1898), a long poem commemorating the harsh rhythms of prison life.

1964 – Leonid Brezhnev becomes leader of the Soviet Communist Party, while Alexei Kosygin becomes the head of government.

Leonid Ilyich Brezhnev (19 December 1906 – 10 November 1982) was a Soviet politician. The fifth leader of the Soviet Union, he served as General Secretary of the Central Committee of the governing Communist Party of the Soviet Union (CPSU) from 1964 until his death in 1982. His 18-year term as general secretary was second only to Joseph Stalin's in duration. While Brezhnev's rule was characterized by political stability and notable foreign policy successes, it was also marked by corruption, inefficiency, and rapidly growing technological gaps with the West.

Brezhnev's conservative, pragmatic approach to leadership significantly stabilized the position of the Soviet Union and its ruling party. Whereas Khrushchev routinely disregarded the rest of the Politburo while exercising his authority, Brezhnev was careful to minimize dissent among the Party membership by reaching decisions through consensus. Additionally, while pushing for détente between the two Cold War superpowers, he achieved Soviet nuclear parity with the United States and legitimized his country's hegemony over Eastern Europe. Furthermore, the massive arms buildup and widespread military interventionism under Brezhnev's regime significantly expanded the Soviet Union's global influence (particularly in the Middle East and Africa).

Conversely, Brezhnev's hostility to political reform ushered in an era of societal decline known as the Brezhnev Stagnation. In addition to pervasive corruption and falling economic growth, this period was characterized by an increasing technological gap between the Soviet Union and the West. Upon coming to power in 1985, Mikhail Gorbachev denounced Brezhnev's government for its pervasive inefficiency and inflexibility before implementing policies to liberalize the Soviet Union.

After 1975, Brezhnev's health rapidly deteriorated and he increasingly withdrew from international affairs. Following years of declining health, he died on 10 November 1982 and was succeeded as general secretary by Yuri Andropov.

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

1821 Born: Rudolf Virchow, German physician, biologist, and politician (d. 1902)

Rudolf Virchow (13 October 1821 – 5 September 1902) was a German physician, anthropologist, pathologist, prehistorian, biologist, writer, editor, and politician. He is known as "the father of modern pathology" and as the founder of social medicine, and to his colleagues, the "Pope of medicine". He received the Copley Medal in 1892. He was a foreign member of the Royal Swedish Academy of Sciences and was elected to the Prussian Academy of Sciences, but he declined to be ennobled as "von Virchow".

Virchow studied medicine at the Friedrich Wilhelm University under Johannes Peter Müller. He worked at the Charité hospital under Robert Froriep, whom he succeeded as the prosector. His investigation of the 1847–1848 typhus epidemic in Upper Silesia laid the foundation for public health in Germany, and paved his political and social careers. From it, he coined a well known aphorism: "Medicine is a social science, and politics is nothing else but medicine on a large scale". He participated in the Revolution of 1848, which led to his expulsion from Charité the next year. He then published a newspaper Die Medizinische Reform (The Medical Reform). He took the first Chair of Pathological Anatomy at the University of Würzburg in 1849. After five years, Charité reinstated him to its new Institute for Pathology. He co-founded the political party Deutsche Fortschrittspartei, and was elected to the Prussian House of Representatives and won a seat in the Reichstag. His opposition to Otto von Bismarck's financial policy resulted in an anecdotal "Sausage Duel", although he supported Bismarck in his anti-Catholic campaigns, which he named Kulturkampf ("culture struggle").

A prolific writer, he produced more than 2000 scientific writings. Cellular Pathology (1858), regarded as the root of modern pathology, introduced the third dictum in cell theory: Omnis cellula e cellula ("All cells come from cells"). He was a co-founder of Physikalisch-Medizinische Gesellschaft in 1849 and Deutsche Gesellschaft für Pathologie in 1897. He founded journals such as Archiv für Pathologische Anatomie und Physiologie und für Klinische Medicin (with Benno Reinhardt in 1847, from 1903 under the title Virchows Archiv), and Zeitschrift für Ethnologie (Journal of Ethnology). The latter is published by German Anthropological Association and the Berlin Society for Anthropology, Ethnology and Prehistory, the societies which he also founded. 

Virchow was the first to describe and christen diseases such as leukemia, chordoma, ochronosis, embolism, and thrombosis. He coined biological terms such as "chromatin", "neuroglia", "agenesis", "parenchyma", "osteoid", "amyloid degeneration", and "spina bifida"; terms such as Virchow's node, Virchow–Robin spaces, Virchow–Seckel syndrome, and Virchow's triad are named after him. His description of the life cycle of a roundworm Trichinella spiralis influenced the practice of meat inspection. He developed the first systematic method of autopsy, and introduced hair analysis in forensic investigation. Virchow was critical of Ignaz Semmelweis and his idea of disinfecting, who said of him, "Explorers of nature recognize no bugbears other than individuals who speculate". He was critical of what he described as "Nordic mysticism" regarding the Aryan race. As an anti-evolutionist, he called Charles Darwin an "ignoramus" and his own student Ernst Haeckel a "fool". He described the original specimen of Neanderthal man as nothing but that of a deformed human.

1822 Died: Antonio Canova, Italian sculptor (b. 1757)

Antonio Canova (1 November 1757 – 13 October 1822) was an Italian Neoclassical sculptor, famous for his marble sculptures. Often regarded as the greatest of the Neoclassical artists, his sculpture was inspired by the Baroque and the classical revival, and has been characterised as having avoided the melodramatics of the former, and the cold artificiality of the latter.

Canova's sculptures fall into three categories: Heroic compositions, compositions of grace, and sepulchral monuments. In each of these, Canova's underlying artistic motivations were to challenge, if not compete, with classical statues.

Canova refused to take in pupils and students, but would hire workers to carve the initial figure from the marble. He had an elaborate system of comparative pointing so that the workers were able to reproduce the plaster form in the selected block of marble. These workers would leave a thin veil over the entire statue so Canova's could focus on the surface of the statue. 

While he worked, he had people read to him select literary and historical texts.

2016 Died: Bhumibol Adulyadej (Rama IX), King of Thailand (b. 1927)

Bhumibol Adulyadej (5 December 1927 – 13 October 2016), conferred with the title King Bhumibol the Great in 1987 (officially conferred by King Vajiralongkorn in 2019), was the ninth monarch of Thailand from the Chakri dynasty, titled Rama IX. Reigning since 9 June 1946, he was the world's longest-reigning current head of state from the death of Emperor Hirohito of Japan in 1989 until his own death in 2016,, and is both the second-longest reigning monarch of all time and the longest-reigning monarch to have reigned only as an adult, reigning for 70 years and 126 days. During his reign, he was served by a total of 30 prime ministers beginning with Pridi Banomyong and ending with Prayut Chan-o-cha.

Forbes estimated Bhumibol's fortune – including property and investments managed by the Crown Property Bureau, a body that is neither private nor government-owned (assets managed by the Bureau were owned by the crown as an institution, not by the monarch as an individual) to be US$30 billion in 2010, and he headed the magazine's list of the "world's richest royals" from 2008 to 2013 although the same magazine also estimated the worth of the British monarchy triple that of the Thai. In May 2014, Bhumibol's wealth was again listed as US$30 billion. 

After a period of deteriorating health which left him hospitalized on several occasions, Bhumibol died on 13 October 2016 in Siriraj Hospital. He was generally highly revered by the people in Thailand – some saw him as close to divine. Notable political activists and Thai citizens who criticized the king or the institution of monarchy were often forced into exile or to suffer frequent imprisonments. Yet many cases were dropped before being proceeded or were eventually given royal pardon. His cremation was held on 26 October 2017 at the royal crematorium at Sanam Luang. His son, Maha Vajiralongkorn, succeeded him as King.
