January 23rd in stamps Blaise Pascal, Andrija Mohorovičić, Django Reinhardt, Edvard Munch

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

1656 – Blaise Pascal publishes the first of his Lettres provinciales.

Blaise Pascal (19 June 1623 – 19 August 1662) was a French mathematician, physicist, inventor, writer and Catholic theologian. He was a child prodigy who was educated by his father, a tax collector in Rouen. Pascal's earliest work was in the natural and applied sciences, where he made important contributions to the study of fluids, and clarified the concepts of pressure and vacuum by generalising the work of Evangelista Torricelli. Pascal also wrote in defence of the scientific method.

In 1642, while still a teenager, he started some pioneering work on calculating machines. After three years of effort and 50 prototypes, he built 20 finished machines (called Pascal's calculators and later Pascalines) over the following 10 years, establishing him as one of the first two inventors of the mechanical calculator.

Pascal was an important mathematician, helping create two major new areas of research: he wrote a significant treatise on the subject of projective geometry at the age of 16, and later corresponded with Pierre de Fermat on probability theory, strongly influencing the development of modern economics and social science. Following Galileo Galilei and Torricelli, in 1647, he rebutted Aristotle's followers who insisted that nature abhors a vacuum. Pascal's results caused many disputes before being accepted.

In 1646, he and his sister Jacqueline identified with the religious movement within Catholicism known by its detractors as Jansenism. Following a religious experience in late 1654, he began writing influential works on philosophy and theology. His two most famous works date from this period: the Lettres provinciales and the Pensées, the former set in the conflict between Jansenists and Jesuits. In that year, he also wrote an important treatise on the arithmetical triangle. Between 1658 and 1659, he wrote on the cycloid and its use in calculating the volume of solids.

Throughout his life, Pascal was in frail health, especially after the age of 18; he died just two months after his 39th birthday.

1857 Born: Andrija Mohorovičić, Croatian meteorologist and seismologist (d. 1936)

Andrija Mohorovičić (23 January 1857 – 18 December 1936) was a Croatian meteorologist and seismologist. He is best known for the eponymous Mohorovičić discontinuity and is considered as one of the founders of modern seismology.

On 8 October 1909 there was an earthquake with its epicentre in the Pokuplje region, 39 km southeast of Zagreb. A number of seismographs had been installed beforehand and these provided invaluable data, upon which he made new discoveries. He concluded that when seismic waves strike the boundary between different types of material, they are reflected and refracted, just as light is when striking a prism, and that when earthquakes occur, two waves—longitudinal and transverse—propagate through the soil with different velocities. By analyzing data from more observation posts, Mohorovičić concluded that the Earth has several layers above a core. He was the first to establish, based on the evidence from seismic waves, the discontinuity that separates the Earth's crust from its mantle. This is now called the Mohorovičić discontinuity or (because of the complexity of that name) Moho. According to Mohorovičić, a layered structure would explain the observation of depths where seismic waves change speed and the difference in chemical composition between rocks from the crust and those from the mantle. From the data, he estimated the thickness of the upper layer (crust) to be 54 km. We know today that the crust is 5–9 km below the ocean floor and 25–60 km below the continents, which are carried on tectonic plates. Subsequent study of the Earth's interior confirmed the existence of the discontinuity under all continents and oceans.

Mohorovičić assumed that the velocity of seismic waves increases with the depth. The function he proposed to calculate the velocity of seismic waves is called the Mohorovičić law. He developed a method for determining earthquake epicenters and constructed curves giving the travel times of seismic waves over distances of up to 10,000 miles from the source. He also proposed the construction of a new type of seismograph for recording the ground horizontal movement, but due to lack of funds the project was never realized.

As early as 1909 Mohorovičić started giving lectures that both architects and building contractors should follow, ahead of his time setting some of the basic principles of earthquake-resistant design. Mohorovičić's theories were visionary and were only truly understood many years later from detailed observations of the effects of earthquakes on buildings, deep focus earthquakes, locating earthquake epicenters, Earth models, seismographs, harnessing the energy of the wind, hail defence and other related elements of the geological body of knowledge known as geoscience.

1910 Born: Django Reinhardt, Belgian guitarist and composer (d. 1953)

Jean Reinhardt (23 January 1910 – 16 May 1953), known to all by his Romani nickname Django, was a Belgian-born Romani-French jazz guitarist and composer. He was the first major jazz talent to emerge from Europe and remains the most significant.

With violinist Stéphane Grappelli, Reinhardt formed the Paris-based Quintette du Hot Club de France in 1934. The group was among the first to play jazz that featured the guitar as a lead instrument. Reinhardt recorded in France with many visiting American musicians, including Coleman Hawkins and Benny Carter, and briefly toured the United States with Duke Ellington's orchestra in 1946. He died suddenly of a stroke at the age of 43.

Reinhardt's most popular compositions have become standards within gypsy jazz, including "Minor Swing", "Daphne", "Belleville", "Djangology", "Swing '42", and "Nuages". Jazz guitarist Frank Vignola claims that nearly every major popular-music guitarist in the world has been influenced by Reinhardt. Over the last few decades, annual Django festivals have been held throughout Europe and the U.S., and a biography has been written about his life. In February 2017, the Berlin International Film Festival held the world premiere of the French film Django.

1944 Died: Edvard Munch, Norwegian painter and illustrator (b. 1863)

Edvard Munch (12 December 1863 – 23 January 1944) was a Norwegian painter. His best known work, The Scream, has become one of the most iconic images of world art.

His childhood was overshadowed by illness, bereavement and the dread of inheriting a mental condition that ran in the family. Studying at the Royal School of Art and Design in Kristiania (today's Oslo), Munch began to live a bohemian life under the influence of nihilist Hans Jæger, who urged him to paint his own emotional and psychological state ('soul painting'). From this emerged his distinctive style.

Travel brought new influences and outlets. In Paris, he learned much from Paul Gauguin, Vincent van Gogh and Henri de Toulouse-Lautrec, especially their use of colour. In Berlin, he met Swedish dramatist August Strindberg, whom he painted, as he embarked on his major canon The Frieze of Life, depicting a series of deeply-felt themes such as love, anxiety, jealousy and betrayal, steeped in atmosphere.

The Scream was conceived in Kristiania. According to Munch, he was out walking at sunset, when he 'heard the enormous, infinite scream of nature'. The painting's agonised face is widely identified with the angst of the modern person. Between 1893 and 1910, he made two painted versions and two in pastels, as well as a number of prints. One of the pastels would eventually command the fourth highest nominal price paid for a painting at auction.

As his fame and wealth grew, his emotional state remained insecure. He briefly considered marriage, but could not commit himself. A breakdown in 1908 forced him to give up heavy drinking, and he was cheered by his increasing acceptance by the people of Kristiania and exposure in the city's museums. His later years were spent working in peace and privacy. Although his works were banned in Nazi Germany, most of them survived World War II, securing him a legacy.

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

1841 – Hong Kong Island is occupied by the British.

Hong Kong Island is an island in the southern part of Hong Kong. It has a population of 1,289,500 and its population density is 16,390/km2, as of 2008. The island had a population of about 3,000 inhabitants scattered in a dozen fishing villages when it was occupied by the United Kingdom in the First Opium War (1839–1842). In 1842, the island was formally ceded in perpetuity to the UK under the Treaty of Nanking and the City of Victoria was then established on the island by the British Force in honour of Queen Victoria. The island was given as a gesture of goodwill back to China at the end of the New Territories lease, to ensure continued peace and fair trading in the area.

The Central area on the island is the historical, political and economic centre of Hong Kong. The northern coast of the island forms the southern shore of the Victoria Harbour, which is largely responsible for the development of Hong Kong due to its deep waters favoured by large trade ships.

The island is home to many of the most famous sights in Hong Kong, such as "The Peak", Ocean Park, many historical sites and various large shopping centres. The mountain ranges across the island are also famous for hiking. The northern part of Hong Kong Island, together with Kowloon and Tsuen Wan New Town, forms the core urban area of Hong Kong. Their combined area is approximately 88.3 square kilometres (34.1 square miles) and their combined population (that of the northern part of the island and of Kowloon) is approximately 3,156,500, reflecting a population density of 35,700/km2 (91,500/sq. mi.).

The island is often referred to locally as "Hong Kong side" or "Island side". Suffix "side" applied to other locations (e.g. China-side and Kowloon Walled City-side), the sole remnant of which is "Kowloon side" when indicating the two sides of the harbour. The form was once more common in Britain than now, such as south/Surrey-side and endures in British placenames like Cheapside, Tyneside, and Teesside, not all of which have an obvious watercourse or boundary.

1891 Died: Kalākaua, king of Hawaii (b. 1836)

Kalākaua (David Laʻamea Kamananakapu Mahinulani Naloiaehuokalani Lumialani Kalākaua; November 16, 1836 – January 20, 1891), sometimes called The Merrie Monarch, was the last king and penultimate monarch of the Kingdom of Hawaiʻi, reigning from February 12, 1874, until his death. Succeeding Lunalilo, he was elected to the vacant throne of Hawaiʻi against Queen Emma. Kalākaua had a convivial personality and enjoyed entertaining guests with his singing and ukulele playing. At his coronation and his birthday jubilee, the hula that had been banned from public in the kingdom became a celebration of Hawaiian culture.

During his reign, the Reciprocity Treaty of 1875 brought great prosperity to the kingdom. Its renewal continued the prosperity but allowed the United States to have exclusive use of Pearl Harbor. In 1881, he took a trip around the world to encourage the immigration of contract sugar plantation workers. Kalākaua wanted Hawaiians to broaden their education beyond their nation. He instituted a government financed program to sponsor qualified students to be sent abroad to further their education. Two of Kalākaua's projects, the statue of Kamehameha I and the rebuilding of ʻIolani Palace, were expensive endeavors but are popular tourist attractions today.

Extravagant expenditures and his plans for a Polynesian confederation played into the hands of annexationists who were already working towards a United States takeover of Hawaiʻi. In 1887, he was pressured to sign a new constitution that made the monarchy little more than a figurehead position. He had faith in his sister Liliʻuokalani's abilities to rule as regent when he named her as his heir-apparent following the death of their brother, William Pitt Leleiohoku II, in 1877. After his death, she became the last monarch of Hawaiʻi.

1936 – King George V of the United Kingdom dies. His eldest son succeeds to the throne, becoming Edward VIII. The title Prince of Wales is not used for another 22 years.

George V (George Frederick Ernest Albert; 3 June 1865 – 20 January 1936) was King of the United Kingdom and the British Dominions, and Emperor of India, from 6 May 1910 until his death in 1936.

Born during the reign of his grandmother Queen Victoria, George was third in the line of succession behind his father, Prince Albert Edward, and his own elder brother, Prince Albert Victor. From 1877 to 1891, George served in the Royal Navy, until the unexpected death of his elder brother in early 1892 put him directly in line for the throne. On the death of his grandmother in 1901, George's father ascended the throne as Edward VII, and George was created Prince of Wales. He became king-emperor on his father's death in 1910.

George V's reign saw the rise of socialism, communism, fascism, Irish republicanism, and the Indian independence movement, all of which radically changed the political landscape. The Parliament Act 1911 established the supremacy of the elected British House of Commons over the unelected House of Lords. As a result of the First World War (1914–1918), the empires of his first cousins Nicholas II of Russia and Wilhelm II of Germany fell, while the British Empire expanded to its greatest effective extent. In 1917, George became the first monarch of the House of Windsor, which he renamed from the House of Saxe-Coburg and Gotha as a result of anti-German public sentiment. In 1924 he appointed the first Labour ministry and in 1931 the Statute of Westminster recognised the dominions of the Empire as separate, independent states within the British Commonwealth of Nations. He had smoking-related health problems throughout much of his later reign and at his death was succeeded by his eldest son, Edward VIII.

1937 – Franklin D. Roosevelt and John Nance Garner are sworn in for their second terms as U.S. President and U.S. Vice President; it is the first time a Presidential Inauguration takes place on January 20 since the 20th Amendment changed the dates of presidential terms.

Franklin Delano Roosevelt (January 30, 1882 – April 12, 1945), often referred to by his initials FDR, was an American politician who served as the 32nd president of the United States from 1933 until his death in 1945. A member of the Democratic Party, he won a record four presidential elections and became a central figure in world events during the first half of the 20th century. Roosevelt directed the federal government during most of the Great Depression, implementing his New Deal domestic agenda in response to the worst economic crisis in U.S. history. As a dominant leader of his party, he built the New Deal Coalition, which realigned American politics into the Fifth Party System and defined American liberalism throughout the middle third of the 20th century. His third and fourth terms were dominated by World War II, which ended shortly after he died in office. He is rated by scholars as one of the three greatest U.S. presidents, along with George Washington and Abraham Lincoln, but has also been subject to substantial criticism.



Roosevelt was born in Hyde Park, New York, to a Dutch American family made well known by the reputation of Theodore Roosevelt, the 26th president of the United States, and William Henry Aspinwall. FDR graduated from Groton School and Harvard College and attended Columbia Law School but left after passing the bar exam to practice law in New York City. In 1905, he married his fifth cousin once removed, Eleanor Roosevelt. They had six children, of whom five survived into adulthood. He won election to the New York State Senate in 1910, and then served as Assistant Secretary of the Navy under President Woodrow Wilson during World War I. Roosevelt was James M. Cox's running mate on the Democratic Party's 1920 national ticket, but Cox was defeated by Republican Warren G. Harding. In 1921, Roosevelt contracted a paralytic illness, believed at the time to be polio, and his legs became permanently paralyzed. While attempting to recover from his condition, Roosevelt founded the treatment center in Warm Springs, Georgia, for people with poliomyelitis. In spite of being unable to walk unaided, Roosevelt returned to public office by winning election as Governor of New York in 1928. He served as governor from 1929 to 1933, promoting programs to combat the economic crisis besetting the United States.



In the 1932 presidential election, Roosevelt defeated Republican President Herbert Hoover in a landslide. Roosevelt took office in the midst of the Great Depression, the worst economic crisis in U.S. history. During the first 100 days of the 73rd United States Congress, Roosevelt spearheaded unprecedented federal legislation and issued a profusion of executive orders that instituted the New Deal—a variety of programs designed to produce relief, recovery, and reform. He created numerous programs to provide relief to the unemployed and farmers while seeking economic recovery with the National Recovery Administration and other programs. He also instituted major regulatory reforms related to finance, communications, and labor, and presided over the end of Prohibition. He harnessed radio to speak directly to the American people, giving 30 "fireside chat" radio addresses during his presidency and becoming the first American president to be televised. The economy having improved rapidly from 1933 to 1936, Roosevelt won a landslide reelection in 1936. However, the economy then relapsed into a deep recession in 1937 and 1938. After the 1936 election, Roosevelt sought passage of the Judiciary Reorganization Bill of 1937 (the "court packing plan"), which would have expanded the size of the Supreme Court of the United States. The bipartisan Conservative Coalition that formed in 1937 prevented passage of the bill and blocked the implementation of further New Deal programs and reforms. Major surviving programs and legislation implemented under Roosevelt include the Securities and Exchange Commission, the National Labor Relations Act, the Federal Deposit Insurance Corporation, Social Security, and the Fair Labor Standards Act of 1938.

The United States reelected FDR in 1940 for his third term, making him the only U.S. President to serve for more than two terms. With World War II looming after 1938, Roosevelt gave strong diplomatic and financial support to China, the United Kingdom and eventually the Soviet Union while the U.S. remained officially neutral. Following the Japanese attack on Pearl Harbor on December 7, 1941, an event he famously called "a date which will live in infamy", Roosevelt obtained a congressional declaration of war on Japan, and, a few days later, on Germany and Italy. Assisted by his top aide Harry Hopkins and with very strong national support, he worked closely with British Prime Minister Winston Churchill, Soviet leader Joseph Stalin and Chinese Generalissimo Chiang Kai-shek in leading the Allied Powers against the Axis Powers. Roosevelt supervised the mobilization of the U.S. economy to support the war effort, and implemented a Europe first strategy, making the defeat of Germany a priority over that of Japan. He also initiated the development of the world's first atomic bomb, and worked with the other Allied leaders to lay the groundwork for the United Nations and other post-war institutions. Roosevelt won reelection in 1944, but with his physical health declining during the war years, he died in April 1945, less than three months into his fourth term. The Axis Powers surrendered to the Allies in the months following Roosevelt's death, during the presidency of his successor, Harry S. Truman.

1953 – Dwight D. Eisenhower is inaugurated as the 34th President of the United States of America.

Dwight David "Ike" Eisenhower (October 14, 1890 – March 28, 1969), was an American army general who served as the 34th president of the United States from 1953 to 1961. During World War II, he became a five-star general in the Army and served as Supreme Commander of the Allied Expeditionary Force in Europe. He was responsible for planning and supervising the invasion of North Africa in Operation Torch in 1942–43 and the successful invasion of Normandy in 1944–45 from the Western Front.

Eisenhower was born David Dwight Eisenhower, and raised in Abilene, Kansas, in a large family of mostly Pennsylvania Dutch ancestry. His family had a strong religious background. His mother became a Jehovah's Witness. Eisenhower, however, did not belong to any organized church until 1952. He graduated from West Point in 1915 and later married Mamie Doud, with whom he had two sons. During World War I, he was denied a request to serve in Europe and instead commanded a unit that trained tank crews. Following the war, he served under various generals and was promoted to the rank of brigadier general in 1941. After the United States entered World War II, Eisenhower oversaw the invasions of North Africa and Sicily before supervising the invasions of France and Germany. After the war, he served as Army Chief of Staff (1945–1948), as president of Columbia University (1948–1953) and as the first Supreme Commander of NATO (1951–1952).

In 1952, Eisenhower entered the presidential race as a Republican to block the isolationist foreign policies of Senator Robert A. Taft; Taft opposed NATO and wanted no foreign entanglements. Eisenhower won that election and the 1956 election in landslides, both times defeating Adlai Stevenson II. Eisenhower's main goals in office were to contain the spread of communism and reduce federal deficits. In 1953, he threatened to use nuclear weapons until China agreed to peace terms in the Korean War. China did agree and an armistice resulted which remains in effect. His New Look policy of nuclear deterrence prioritized inexpensive nuclear weapons while reducing funding for expensive Army divisions. He continued Harry S. Truman's policy of recognizing Taiwan as the legitimate government of China, and he won congressional approval of the Formosa Resolution. His administration provided major aid to help the French fight off Vietnamese Communists in the First Indochina War. After the French left, he gave strong financial support to the new state of South Vietnam. He supported regime-changing military coups in Iran and Guatemala orchestrated by his own administration. During the Suez Crisis of 1956, he condemned the Israeli, British, and French invasion of Egypt, and he forced them to withdraw. He also condemned the Soviet invasion during the Hungarian Revolution of 1956 but took no action. After the Soviet Union launched Sputnik in 1957, Eisenhower authorized the establishment of NASA, which led to the Space Race. He deployed 15,000 soldiers during the 1958 Lebanon crisis. Near the end of his term, he failed to set up a summit meeting with the Soviets when a U.S. spy plane was shot down over the Soviet Union. He approved the Bay of Pigs invasion, which was left to John F. Kennedy to carry out.

On the domestic front, Eisenhower was a moderate conservative who continued New Deal agencies and expanded Social Security. He covertly opposed Joseph McCarthy and contributed to the end of McCarthyism by openly invoking executive privilege. He signed the Civil Rights Act of 1957 and sent Army troops to enforce federal court orders which integrated schools in Little Rock, Arkansas. His largest program was the Interstate Highway System. He promoted the establishment of strong science education via the National Defense Education Act. His two terms saw widespread economic prosperity except for a minor recession in 1958. In his farewell address to the nation, he expressed his concerns about the dangers of massive military spending, particularly deficit spending and government contracts to private military manufacturers, which he dubbed "the military–industrial complex". Historical evaluations of his presidency place him among the upper tier of American presidents.

1961 – John F. Kennedy is inaugurated the 35th President of the United States of America, becoming the second youngest man to take the office, and the first Catholic.

John Fitzgerald Kennedy (May 29, 1917 – November 22, 1963), often referred to by his initials JFK and Jack, was an American politician who served as the 35th president of the United States from January 1961 until his assassination in November 1963. Kennedy served at the height of the Cold War, and the majority of his work as president concerned relations with the Soviet Union and Cuba. A Democrat, Kennedy represented Massachusetts in the U.S. House of Representatives and Senate prior to becoming president.

Kennedy was born into a wealthy, political family in Brookline, Massachusetts. He graduated from Harvard University in 1940, before joining the U.S. Naval Reserve the following year. During World War II, he commanded a series of PT boats in the Pacific theater and earned the Navy and Marine Corps Medal for his service. After a brief stint in journalism, Kennedy represented a working-class Boston district in the U.S. House of Representatives from 1947 to 1953. He was subsequently elected to the U.S. Senate and served as the junior Senator from Massachusetts from 1953 to 1960. While in the Senate, Kennedy published his book, Profiles in Courage, which won a Pulitzer Prize. In the 1960 presidential election, he narrowly defeated Republican opponent Richard Nixon, who was the incumbent vice president.

Kennedy's administration included high tensions with communist states in the Cold War. As a result, he increased the number of American military advisers in South Vietnam. In April 1961, he authorized an attempt to overthrow the Cuban government of Fidel Castro in the Bay of Pigs Invasion. Kennedy authorized the Cuban Project in November 1961. He rejected Operation Northwoods (plans for false flag attacks to gain approval for a war against Cuba) in March 1962. However, his administration continued to plan for an invasion of Cuba in the summer of 1962. The following October, U.S. spy planes discovered Soviet missile bases had been deployed in Cuba; the resulting period of tensions, termed the Cuban Missile Crisis, nearly resulted in the breakout of a global thermonuclear conflict. The Strategic Hamlet Program began in Vietnam during his presidency. Domestically, Kennedy presided over the establishment of the Peace Corps and the continuation of the Apollo space program. He also supported the civil rights movement, but was only somewhat successful in passing his New Frontier domestic policies.

On November 22, 1963, he was assassinated in Dallas. Vice President Lyndon B. Johnson assumed the presidency upon Kennedy's death. Marxist and former U.S. Marine Lee Harvey Oswald was arrested for the state crime, but he was shot and killed by Jack Ruby two days later. The FBI and the Warren Commission both concluded Oswald had acted alone in the assassination, but various groups contested the Warren Report and believed that Kennedy was the victim of a conspiracy. After Kennedy's death, Congress enacted many of his proposals, including the Civil Rights Act and the Revenue Act of 1964. Kennedy ranks highly in polls of U.S. presidents with historians and the general public. His personal life has also been the focus of considerable sustained interest following public revelations in the 1970s of his chronic health ailments and extramarital affairs.

Here are some events that happened on December 31st. It could be an event or a person that died or was born on that day

1869 Born: Henri Matisse, French painter and sculptor (d. 1954)

Henri Émile Benoît Matisse (31 December 1869 – 3 November 1954) was a French artist, known for both his use of colour and his fluid and original draughtsmanship. He was a draughtsman, printmaker, and sculptor, but is known primarily as a painter. Matisse is commonly regarded, along with Pablo Picasso, as one of the artists who best helped to define the revolutionary developments in the visual arts throughout the opening decades of the twentieth century, responsible for significant developments in painting and sculpture.

The intense colorism of the works he painted between 1900 and 1905 brought him notoriety as one of the Fauves (wild beasts). Many of his finest works were created in the decade or so after 1906, when he developed a rigorous style that emphasized flattened forms and decorative pattern. In 1917, he relocated to a suburb of Nice on the French Riviera, and the more relaxed style of his work during the 1920s gained him critical acclaim as an upholder of the classical tradition in French painting. After 1930, he adopted a bolder simplification of form. When ill health in his final years prevented him from painting, he created an important body of work in the medium of cut paper collage.

His mastery of the expressive language of colour and drawing, displayed in a body of work spanning over a half-century, won him recognition as a leading figure in modern art

1878 – Karl Benz, working in Mannheim, Germany, filed for a patent on his first reliable two-stroke gas engine, and he was granted the patent in 1879.

Karl Friedrich Benz (25 November 1844 – 4 April 1929) was a German engine designer and automobile engineer.
The Benz Patent-Motorwagen ("patent motorcar"), built in 1885, is widely regarded as the world's first production automobile, that is, a vehicle designed to be propelled by an internal combustion engine. The original cost of the vehicle in 1885 was 600 imperial German marks, approximately 150 US dollars (equivalent to $4,183 in 2018). The vehicle was awarded the German patent number 37435, for which Karl Benz applied on 29 January 1886. Following official procedures, the date of the application became the patent date for the invention once the patent was granted, which occurred in November of that year.

Here are some stamps depicting Benz or his car from Germany and Hungary

1908 Born: Simon Wiesenthal, Ukrainian-Austrian Nazi hunter and author (d. 2005)

Simon Wiesenthal (31 December 1908 – 20 September 2005) was a Jewish Austrian Holocaust survivor, Nazi hunter, and writer. He studied architecture and was living in Lwów at the outbreak of World War II. He survived the Janowska concentration camp (late 1941 to September 1944), the Kraków-Płaszów concentration camp (September to October 1944), the Gross-Rosen concentration camp, a death march to Chemnitz, Buchenwald, and the Mauthausen-Gusen concentration camp (February to 5 May 1945).

After the war, Wiesenthal dedicated his life to tracking down and gathering information on fugitive Nazi war criminals so that they could be brought to trial. In 1947, he co-founded the Jewish Historical Documentation Centre in Linz, Austria, where he and others gathered information for future war crime trials and aided refugees in their search for lost relatives. He opened the Documentation Centre of the Association of Jewish Victims of the Nazi Regime in Vienna in 1961 and continued to try to locate missing Nazi war criminals. He played a small role in locating Adolf Eichmann, who was captured in Buenos Aires in 1960, and worked closely with the Austrian justice ministry to prepare a dossier on Franz Stangl, who was sentenced to life imprisonment in 1971.

In the 1970s and 1980s, Wiesenthal was involved in two high-profile events involving Austrian politicians. Shortly after Bruno Kreisky was inaugurated as Austrian chancellor in April 1970, Wiesenthal pointed out to the press that four of his new cabinet appointees had been members of the Nazi Party. Kreisky, angry, called Wiesenthal a "Jewish fascist", likened his organisation to the Mafia, and accused him of collaborating with the Nazis. Wiesenthal successfully sued for libel, the suit ending in 1989. In 1986, Wiesenthal was involved in the case of Kurt Waldheim, whose service in the Wehrmacht and probable knowledge of the Holocaust were revealed in the lead-up to the 1986 Austrian presidential elections. Wiesenthal, embarrassed that he had previously cleared Waldheim of any wrongdoing, suffered much negative publicity as a result of this event.

With a reputation as a storyteller, Wiesenthal was the author of several memoirs containing tales that are only loosely based on actual events. In particular, he exaggerated his role in the capture of Eichmann in 1960. Wiesenthal died in his sleep at age 96 in Vienna on 20 September 2005 and was buried in the city of Herzliya in Israel. The Simon Wiesenthal Center, located in Los Angeles, is named in his honor.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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