Luigi Fantappiè (15 September 1901 – 28 July 1956) was an Italian mathematician, known for work in mathematical analysis and for creating the theory of analytic functionals: he was a student and follower of Vito Volterra. Later in life, he proposed scientific theories of sweeping scope.
Louis Marcel Brillouin (French pronunciation: [lwi maʁsɛl bʁijwɛ̃]; 19 December 1854 – 16 June 1948) was a French physicist and mathematician.
Born in Saint-Martin-lès-Melle, Deux-Sèvres, France, his father was a painter who moved to Paris when Marcel was a boy. There he attended the Lycée Condorcet. The Brillouin family returned to Saint-Martin-lès-Melle during the Franco-Prussian War of 1870 to escape the fighting. There he spent time teaching himself from his grandfather's philosophy books. After the war, he returned to Paris and entered the École Normale Supérieure in 1874 and graduated in 1878. He became a physics assistant to Éleuthère Mascart (his future father-in-law) at the Collège de France, while at the same time working for his doctorates in mathematics and physics, which he gained in 1880 and 1882, respectively. Brillouin then held successive posts as assistant professor of physics at universities in Nancy, Dijon and Toulouse before returning to the École Normale Supérieure in Paris in 1888. Later, he was Professor of Mathematical Physics at the Collège de France from 1900 to retirement in 1931.
In 1911 he was one of only six French physicists invited to the first Solvay Conference. He was awarded the Prix La Caze for 1912.
Brillouin was elected to the Académie des Sciences in 1921. He was an officer of the Legion of Honour.During his career he was the author of over 200 experimental and theoretic papers on a wide range of topics which include the kinetic theory of gases, viscosity, thermodynamics, electricity, and the physics of melting conditions. Most notably he:
built a new model of the Eötvös balance,
wrote on Helmholtz flow and the stability of aircraft,
worked on a theory of the tides.Brillouin died in Paris (16 June 1948). His son Léon Brillouin, also had a prominent career in physics.
Friedrich Simon Archenhold (2 October 1861 in Lichtenau, Kingdom of Prussia – 14 October 1939 in Berlin) was an astronomer who founded the Treptow Observatory (today the Archenhold Observatory) in Berlin-Treptow. He graduated from the Realgymnasium in Lippstadt before entering Friedrich Wilhelm University in 1882, where he and Wilhelm Förster founded the Urania Society at the Berlin University Observatory.
Marcel Gilles Jozef Minnaert (12 February 1893 – 26 October 1970) was a Belgian-Dutch astronomer. He was born in Bruges and died in Utrecht. He is notable for his contributions to astronomy and physics and for a popular book on meteorological optics: Light and colour in the open air, first published in English in 1940.
Carl August von Steinheil (12 October 1801 – 14 September 1870) was a German physicist, inventor, engineer and astronomer.
Max Bense (7 February 1910 in Strasbourg – 29 April 1990 in Stuttgart) was a German philosopher, writer, and publicist, known for his work in philosophy of science, logic, aesthetics, and semiotics. His thoughts combine natural sciences, art, and philosophy under a collective perspective and follow a definition of reality, which – under the term existential rationalism – is able to remove the separation between humanities and natural sciences.
Ernst Philipp Barthel (17 October 1890 in Schiltigheim - 16 February 1953 in Oberkirch (Baden)) was an Alsace philosopher, mathematician, and inventor.In the 1920s and 1930s he taught as a Privatdozent of philosophy at the University of Cologne. From 1924 on Barthel edited the magazine Antäus. Blätter für neues Wirklichkeitsdenken (Journal for new Reality Thinking), which served as the organ of the Gesellschaft für Lebensphilosophie (Society for Life Philosophy) founded by him in Cologne.
Barthel maintained philosophical friendships with his compatriots Albert Schweitzer and Friedrich Lienhard.
Heinrich Carl Franz Emil Timerding (23 January 1873 in Strasbourg – 30 April 1945 in Braunschweig) was a German mathematician, professor at the Braunschweig University of Technology, mainly known for his contributions to probability theory.
He was awarded the Brunswick and the Prussian War Merit Cross, the Ritterkreuz (Knight's Cross) of the Order of Henry the Lion, and in 1938 the Nazi Civil Service Faithful Service Medal.In 1900 he attended Columbia University in New York City the American Mathematical Society's summer meeting, where he read a paper.
Elisabeth Eleonore Anna Justine Heuss-Knapp (née Knapp; 25 January 1882 – 19 July 1952) was a German politician of the Free Democratic Party (FDP), social reformer, author and wife of German president Theodor Heuss. She was the founder of the Müttergenesungswerk charitable organisation officially called Elly Heuss-Knapp Foundation in her honour.
César Vezzani (8 August 1888 – 11 November 1951) was a French/Corsican operatic tenor who became a leading exponent of French grand opera through several decades. (Some sources give his date of birth as 1886.)
