Franz Heinrich Kaiser (25 April 1891 – 13 March 1962) was a German astronomer.He worked at the Heidelberg-Königstuhl Observatory from 1911 to 1914 while working on his Ph.D. there, which he obtained in 1915. During this time, Heidelberg was a center of asteroid discovery, and Kaiser discovered 21 asteroids during his time there.The outer main-belt asteroid 3183 Franzkaiser was named in his memory on 1 September 1993 (M.P.C. 22497).
David Katz (1 October 1884, Kassel – 2 February 1953, Stockholm) was a German-born Swedish psychologist and educator who specialized in Gestalt psychology and phenomenology. He was a professor Emeritus at the University of Stockholm. Prior to the establishment of the Nazi regime in Germany, he served as the chair of psychology and education at the State University of Mecklenburg in Rostock.
Eduard August Grüneisen (26 May 1877 – 5 April 1949) was a German physicist. The dimensionless thermodynamic measure known as Grüneisen parameter is named after him.
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.
Ludwig Otto Blumenthal (20 July 1876 – 12 November 1944) was a German mathematician and professor at RWTH Aachen University.
Gerhard Hessenberg (German: [ˈgɛʁ.hart ˈhɛsənˌbɛrk]; 16 August 1874 – 16 November 1925) was a German mathematician who worked in projective geometry, differential geometry, and set theory.
