Brugsch Theodor (b. 1878-10-11 / d. 1963-07-11)

He was a German internist born in Graz. He became an associate professor in 1910, and practiced medicine at the Charité Hospital in Berlin prior to, and after World War I. In 1917-19 he served with distinction as a physician with the 9th Army in Romania. From 1927 to 1935 he was a professor at the University of Halle. In 1935 Brugsch resigned from the university due to the political climate in 1930s Germany, and opened a private practice in Berlin. After World War II, he returned to the Charité, where he remained for the remainder of his career. His father, Heinrich Karl Brugsch (1827-1894) was a well-known Egyptologist. With Friedrich Kraus he published a 19-volume medical textbook titled Spezielle Pathologie und Therapie (1919-1929), and with Friedrich H. Lewy he published Die Biologie der Person (1926-1930). He was the 1954 recipient of the Goethe Prize, and in 1978 was depicted on the 25-pfennig postage stamp by the East German government. Brugsch's syndrome: a multi-symptom disorder that is similar to Touraine-Solente-Golé syndrome without acromegaly.

Atta
Mohamed. 2001-09-11

33

Born 1968-09-01. Domain:Society. Cause of death:Suicide

On September 10, Atta picked up al-Omari from the Milner Hotel in Boston, Massachusetts, and the two drove their rented Nissan to a Comfort Inn in Portland, Maine, where they arrived at 5:43pm and spent the night in room 232 only to catch a flight back to Boston the following morning. Possibly this was done by the two men to clear airport security under less scrutiny in Maine than they would have faced at Logan Airport in Boston. It was initially reported that Adnan and Ameer Bukhari were the two hijackers who had rented and driven the car. The FBI also states that Atta made a credit-card purchase in Manhattan, New York on the 10th.
The two spent their last night pursuing ordinary activities: making two ATM withdrawals, and a 20-minute stop at Wal-Mart. FBI reports specified that "two middle-eastern men" were seen in the parking lot of a Pizza Hut, but despite alluding to Atta and Marwan, does not explicitly say it was them.
On the morning of September 11, they drove to the Portland International Jetport, and took the 6am Colgan Air (U.S. Airways Express) BE-1900C flight to Logan International Airport in Boston. The two sat in the rearmost seats, next to one another. In Portland, Mohamed Atta was selected by CAPPS, which required his checked bags to undergo extra screening for explosives and involved no extra screening at the passenger security checkpoint.
The connection between the two flights at Logan Airport was within Terminal B, but the two gates were not connected within security. You must cross a parking garage before going through security once again. There are two separate concourses in Terminal B, the south concourse is mainly used by US Airways and the north is mostly American. It was overlooked that there would still be security in Boston because of this distinct detail of the terminal's arrangement.
At the American Airlines concourse, the pair boarded American Airlines Flight 11, where Atta was checked in under the abbreviation "Moham Atta", and was seated in 8D. At 6:45 a.m., while at the Boston airport, Atta took a call from Marwan al-Shehhi, another hijacker. This call was apparently to confirm that the attacks were ready to begin.
At 7:59 a.m., the plane departed from Boston, carrying 81 passengers. The plane's transponder was turned off at 8:28am. At 8:24:38, a voice believed to be Atta's was heard by air traffic controllers, saying: "We have some planes. Just stay quiet and you will be OK. We are returning to the airport. Nobody move, everything will be OK. If you try to make any moves you'll endanger yourself and the airplane. Just stay quiet...".
Seconds after American Airlines Flight 11 crashes into the World Trade Center.Atta is believed to have been the pilot of the plane when it crashed into the north tower of the World Trade Center 23 minutes later at 8:46.40a.m. All aboard the plane were killed.
Because the flight from Portland to Boston had been delayed, his bags did not make it onto Flight 11. When later found by U.S. authorities, they contained airline uniforms, flight manuals, and a four-page document in Arabic, copies of which were also found with the terrorists of the other three planes. It contains a list of instructions, such as "make an oath to die and renew your intentions," "you should feel complete tranquility, because the time between you and your marriage in heaven is very short," and "check your weapon before you leave and long before you leave. You must make your knife sharp and you must not discomfort your animal during the slaughter."

Nabokov
Vladimir. 1977-07-02

Born 1899-04-22. Domain:Writing. Cause of death:Age

In 1922, Nabokov's father was assassinated in Berlin by Russian monarchists as he tried to shelter their real target, Pavel Milyukov, a leader of the Constitutional Democratic Party-in-exile. This episode of mistaken, violent death would echo again and again in the author's fiction, where characters would meet their deaths under mistaken terms. In Pale Fire, for example, the poet Shade is mistaken for a judge who resembles him and is murdered.
Nabokov was born on April 10, 1899 according to the Julian calendar in use in Russia at that time. The Gregorian equivalent is April 22, which is achieved by adding 12 days to the Julian date. Some sources have incorrectly calculated a date of April 23, by inappropriately using the 13-day difference in the calendars that applied only after February 28, 1900. In 'Speak, Memory' Nabokov explains the cause of the error and confirms the correct date of April 22. But he himself celebrated his birthday on April 23, and stated in an interview with The New York Times, "That is also Shakespeare’s and Shirley Temple’s, so I have nothing to lose by saying I was born on the 23d."

In his book Psychology of Invention in the Mathematical Field, Hadamard uses introspection to describe mathematical thought processes. In sharp contrast to authors who identify language and cognition, he describes his own mathematical thinking as largely wordless, often accompanied by mental images that represent the entire solution to a problem. He surveyed 100 of the leading physicists of the day (approximately 1900), asking them how they did their work. Many of the responses mirrored his; some reported seeing mathematical concepts as colors.

Edwin Henry Colpitts was a communications pioneer best known for his invention of the Colpitts oscillator. As research branch chief for Western Electric in the early 1900s, he and scientists under his direction achieved significant advances in the development of oscillators and vacuum tube push–pull amplifiers. In 1915, his team successfully demonstrated the first transatlantic radio telephone. Colpitts died at home in 1949 in Orange, New Jersey, United States and his body was interred in Point de Bute, New Brunswick, Canada. He was survived by his wife Grace Penney Colpitts and his son Donald B. Colpitts. In 1940, Colpitts was called out of retirement to head a committee reviewing the state of sonar development in the United States Navy. The committee report identified critical limitations of American sonar compared with German developments, which spurred American fundamental sonar research. He was awarded the Elliott Cresson Medal in 1948.

Vito Volterra KBE FRS(For) HFRSE (/voʊlˈtɛrə/, Italian: [ˈviːto volˈtɛrra]) was an Italian mathematician and physicist, known for his contributions to mathematical biology and integral equations, being one of the founders of functional analysis. He died in Rome in 1940. In 1900 he married Virginia Almagia, a cousin. Their son Edoardo Volterra (1904–1984) was a famous historian of Roman law. Volterra also had a daughter, Luisa Volterra, who married the biologist Umberto D'Ancona. D'Ancona piqued his father-in-law's interest in biomathematics when he showed Vito a set of data regarding populations of different species of fish in the Adriatic Sea, where decreased fishing activity from the war had led to an increase in the populations of predatory fish species. Vito published an analysis of the dynamics of interacting species of fish the next year.

Jean-Baptiste Étienne Auguste Charcot, better known in France as Commandant Charcot, was a French scientist, medical doctor and polar scientist. His father was the neurologist Jean-Martin Charcot (1825–1893). As a sportsman, he was French rugby XV champion in 1896 and also won a double silver medal in sailing at the 1900 Summer Olympics. In September 1936, back from Greenland, where he went to deliver scientific material to the mission of Paul-Émile Victor who had just crossed the ice sheet in 50 days, after completing a polling mission, the Why-Not? IV makes a stopover in Reykjavik on the 3rd of the month to repair the boat's boiler. Commander Charcot and his crew set sail in good weather on September 15 for Saint-Malo. On September 16, a violent cyclone storm rose and sank the Why Not? IV on the reefs of Álftanes around 5:30 a.m. The toll is 23 dead, 17 missing and only one survivor: the master helmsman Eugène Gonidec, a native of Douarnenez and nicknamed Penguin. He will tell that Commander Charcot, understanding the inevitable destruction of the Pourquoi-Pas? IV on the reefs, freed the seagull Rita, mascot of the boat, from her cage. The frigate captain Charcot, with at his side the captain and officer of the 1st class crews Le Conniat and the master chief pilot of the Floury fleet, remained on board and sank with the ship, according to the purest traditions of the navy. Jean-Baptiste Charcot, who died at sea, but whose body was found, was buried in Paris at the Montmartre cemetery, on October 12, 1936 after a state funeral that took place at Notre-Dame de Paris Cathedral.

Charles "Buddy" Bolden was an African American cornetist and is regarded by contemporaries as a key figure in the development of a New Orleans style of rag-time music which later came to be known as jazz. He was known as King Bolden, and his band was a top draw in New Orleans from about 1900 until 1907, when he was incapacitated by schizophrenia, which was called dementia praecox at that time. Bolden suffered an episode of acute alcoholic psychosis in 1907 at the age of 30. With the full diagnosis of dementia praecox, he was admitted to a mental institution where he spent the rest of his life. Bolden was buried in an unmarked grave in Holt Cemetery, a pauper's graveyard in New Orleans. In 1998 a monument to Bolden was erected in Holt Cemetery, but his exact gravesite remains unknown.

Born 1863-12-18. Domain:Society. Cause of death:Murder

Archduke Franz Ferdinand Carl Ludwig Joseph Maria of Austria was the heir presumptive to the throne of Austria-Hungary. His assassination in Sarajevo is considered the most immediate cause of World War I. Franz Ferdinand was the eldest son of Archduke Karl Ludwig of Austria, the younger brother of Emperor Franz Joseph I of Austria. Following the death of Crown Prince Rudolf in 1889 and the death of Karl Ludwig in 1896, Franz Ferdinand became the heir presumptive to the Austro-Hungarian throne. His courtship of Sophie Chotek, a lady-in-waiting, caused conflict within the imperial household, and their morganatic marriage in 1900 was only allowed after he renounced his descendants' rights to the throne. Franz Ferdinand held significant influence over the military, and in 1913 he was appointed inspector general of the Austro-Hungarian armed forces. On 28 June 1914, Franz Ferdinand and his wife were assassinated in Sarajevo by the 19-year-old Gavrilo Princip, a member of Young Bosnia. Franz Ferdinand's assassination led to the July Crisis and precipitated Austria-Hungary's declaration of war against Serbia, which in turn triggered a series of events that eventually led to Austria-Hungary's allies and Serbia's allies declaring war on each other, starting World War I.

Félix-Marie Delastelle was a French cryptographer, best known for inventing the bifid cipher, first presented in the Revue du Génie civil in 1895 under the name of "cryptographie nouvelle". This cipher combines fractionation with transposition, and was an early cipher to implement the principles of confusion and diffusion. David Kahn described it as a "system of considerable importance in cryptology." Following his retirement in 1900, he rented a single room in a holiday hotel where he wrote a 150 page book Traité Élémentaire de Cryptographie which he completed in May 1901. On hearing news of his brother's sudden death, he collapsed and died in April 1902. His book appeared three months later, published by Gauthier-Villars of Paris.

Carles Antoni Cosme Damià Casagemas i Coll (Carlos Casagemas) was a Spanish painter and poet. He is known for his friendship with Pablo Picasso, who painted several portraits of Casagemas. In October 1900, Casagemas accompanied Picasso to Paris for the Exposition. Eventually, the two took up residence in a vacated studio owned by Isidre Nonell located in Montmartre. Germaine Gargallo Florentin Pichot (best known as Germaine), Germaine's sister (Antoinette Fornerod), and a close friend, Louise "Odette" Lenoir became models and constant companions of Picasso and Casagemas. Casagemas quickly fell in love with Germaine, while Odette began sleeping with Picasso. Despite his deep feelings for Germaine, Casagemas, due to his impotence, could not consummate their relationship and quickly fell into a deep depression. On February 17, 1901, Casagemas arranged a farewell dinner for himself at the Hippodrome Cafe in Paris. He invited Germaine and a few friends, including Manuel Pallarés and Manolo Hugué. At approximately 9pm and after many rounds of wine and absinthe, Casagemas asked Germaine one final time if she would marry him. When she refused, he drew a pistol and shot at her. The bullet did not strike her, but she fell to the ground. Casagemas then turned the gun and shot himself in the right temple. He died in a hospital later that evening.

O'Flahertie Wills Wilde
Oscar Fingan (alias: Oscar Wilde). 1900-11-30

46

Born 1854-10-16. Domain:Writing. Cause of death:Infection

Wilde made a complaint of criminal libel against Lord Alfred Douglas's father, the ninth Marquess of Queensberry, for leaving him a calling card at his club. The offending card read "For Oscar Wilde, posing Somdomite [sic]". The Marquess was arrested and later freed on bail.
The Marqueese decided to counter-attack. On May 25, 1895 Wilde was convicted of gross indecency and sentenced to two years' hard labour. His conviction angered some observers, one of whom demanded, in a published letter, "Why does not the Crown prosecute every boy at a public or private school or half the men in the Universities?" in reference to the presumed pederastic proclivities of English upper class men.
Prison was unkind to Wilde's health and after he was released on May 19, 1897 he spent his last three years penniless, in self-imposed exile from society and artistic circles. He went under the assumed name of Sebastian Melmoth, after the famously "penetrated" Saint Sebastian and the devilish central character of Wilde's great-uncle Charles Robert Maturin's gothic novel Melmoth the Wanderer.
Wilde died of cerebral meningitis. Different opinions are given on the cause of the meningitis; Richard Ellmann claimed it was syphilitic; Merlin Holland, Wilde's grandson, thought this to be a misconception, noting that Wilde's meningitis followed a surgical intervention, perhaps a mastoidectomy; Wilde's physicians, Dr. Paul Cleiss and A'Court Tucker, reported that the condition stemmed from an old suppuration of the right ear (une ancienne suppuration de l'oreille droite d'ailleurs en traitement depuis plusieurs années) and did not allude to syphilis. Most modern scholars and doctors agree that syphilis was unlikely to have been the cause of his death.

Bruno Abdank-Abakanowicz was a Polish mathematician, inventor, and electrical engineer. He invented the integraph, a form of the integrator, which was patented in 1880, and was henceforth produced by the Swiss firm Coradi. Among his other patents were the parabolagraph, the spirograph, the electric bell used in trains, and an electric arc lamp of his own design. Abakanowicz published several works, including works on statistics, integrators and numerous popular scientific works, such as one describing his integraph. He was also hired by the French government as an expert on electrification and was the main engineer behind the electrification of, among other places, the city of Lyon. His patents allowed him to become a wealthy man and made him receive the Legion d'Honneur in 1889. Around that time he retired to a small island in Trégastel, off the coast of Brittany, where between 1892 and 1896 he erected a neo-Gothic manor. Although the construction works were not finished in Abakanowicz's lifetime, the castle of Costaérès became a notable centre of Polish emigree culture, housing many notable artists, scientists and politicians. Among frequent guests of Abakanowicz were Aleksander Gierymski, Władysław Mickiewicz, Leon Wyczółkowski and Henryk Sienkiewicz. Bruno Abakanowicz died suddenly on 29 August 1900. In his will, he made Sienkiewicz the tutor of his sole daughter Zofia, who later graduated from the London School of Economics and the Sorbonne and was murdered during World War II at the Auschwitz concentration camp.

Nietzsche
Friedrich. 1900-08-25

56

Born 1844-10-15. Domain:Philosophy. Cause of death:Stroke

His style, and radical questioning of the value and objectivity of truth, raise considerable problems of interpretation, generating an extensive secondary literature in both continental and analytic philosophy. Nonetheless, his key ideas include interpreting tragedy as an affirmation of life, an eternal recurrence that has become subject to numerous interpretations, a reversal of Platonism, and a repudiation of (especially 19th-century) Christianity.
Commentators have frequently diagnosed a syphilitic infection as the cause of the illness. While most commentators regard Nietzsche's breakdown as unrelated to his philosophy, some, including Georges Bataille and René Girard, argue that his breakdown may have been caused by a psychological maladjustment brought on by his philosophy.
In 1898 and 1899, Nietzsche suffered from at least two strokes which partially paralysed him and left him unable to speak or walk.
After contracting pneumonia in mid-August 1900, he had another stroke during the night of August 24 / August 25, and then died about noon on August 25.

He is best known for being an independent co-discoverer of the Frenet–Serret formulas. He wrote six out of the nine formulas, which at that time were not expressed in vector notation. These formulas are important in the theory of space curves (differential geometry), and they were presented in his doctoral thesis at Toulouse in 1847. That year he became a professor at Toulouse, and one year later, 1848, he became professor of mathematics at Lyon. He also was director of an astronomical observatory at Lyon. Four years later, in 1852, he published the Frenet formulas in the Journal de Mathématiques Pures et Appliquées.

Eugenio Beltrami was an Italian mathematician notable for his work concerning differential geometry and mathematical physics. His work was noted especially for clarity of exposition. He was the first to prove consistency of non-Euclidean geometry by modeling it on a surface of constant curvature, the pseudosphere, and in the interior of an n-dimensional unit sphere, the so-called Beltrami–Klein model. He also developed singular value decomposition for matrices, which has been subsequently rediscovered several times. Beltrami's use of differential calculus for problems of mathematical physics indirectly influenced development of tensor calculus by Gregorio Ricci-Curbastro and Tullio Levi-Civita.
