Thomas Michael "Tim" Scanlon (; born 1940), usually cited as T. M. Scanlon, is an American philosopher. At the time of his retirement in 2016, he was the Alford Professor of Natural Religion, Moral Philosophy, and Civil Polity in Harvard University's Department of Philosophy, where he had taught since 1984. He was elected to the American Philosophical Society in 2018.
Erwin Finlay-Freundlich (German: [ˈfʀɔɪntlɪç]; 29 May 1885 – 24 July 1964) was a German astronomer, a pupil of Felix Klein. Freundlich was a working associate of Albert Einstein and introduced experiments for which the general theory of relativity could be tested by astronomical observations based on the gravitational redshift.
Helmuth Plessner (4 September 1892, Wiesbaden – 12 June 1985, Göttingen) was a German philosopher and sociologist, and a primary advocate of "philosophical anthropology".
Alfred Theodor Brauer (April 9, 1894 – December 23, 1985) was a German-American mathematician who did work in number theory. He was born in Charlottenburg, and studied at the University of Berlin. As he served Germany in World War I, even being injured in the war, he was able to keep his position longer than many other Jewish academics who had been forced out after Hitler's rise to power. In 1935 he lost his position and in 1938 he tried to leave Germany, but was not able to until the following year. He initially worked in the Northeast, but in 1942 he settled into a position at the University of North Carolina at Chapel Hill. A good deal of his works, and the Alfred T. Brauer library, would be linked to this university. He occasionally taught at Wake Forest University after he retired from Chapel Hill at 70. He died in North Carolina, aged 91.
He was the brother of the mathematician Richard Brauer, who was the founder of modular representation theory.
Helmut Hasse (German: [ˈhasə]; 25 August 1898 – 26 December 1979) was a German mathematician working in algebraic number theory, known for fundamental contributions to class field theory, the application of p-adic numbers to local class field theory and diophantine geometry (Hasse principle), and to local zeta functions.
Karl Menninger (October 6, 1898 – October 2, 1963) was a German teacher of and writer about mathematics. His major work was Zahlwort und Ziffer (1934,; English trans., Number Words and Number Symbols), about non-academic mathematics in much of the world. (The omission of Africa was rectified by Claudia Zaslavsky in her book Africa Counts.)
Karl August Reinhardt (27 January 1895 – 27 April 1941) was a German mathematician whose research concerned geometry, including polygons and tessellations. He solved one of the parts of Hilbert's eighteenth problem, and is the namesake of the Reinhardt polygons.
Wilhelm Lenz (February 8, 1888 in Frankfurt am Main – April 30, 1957 in Hamburg) was a German physicist, most notable for his invention of the Ising model and for his application of the Laplace–Runge–Lenz vector to the old quantum mechanical treatment of hydrogen-like atoms.
Arthur Scherbius (30 October 1878 – 13 May 1929) was a German electrical engineer who invented the mechanical cipher Enigma machine. He patented the invention and later sold the machine under the brand name Enigma.
Scherbius offered unequalled opportunities and showed the importance of cryptography to both military and civil intelligence.
