Rudolph Ernest Langer , also Rudolf, (March 8, 1894 - March 11, 1968 ) was an American mathematician .
Rudolph Langer was the brother of Walter Charles Langer and William L. Langer . He received his doctorate in 1922 at Harvard University under George David Birkhoff on boundary value problems of differential equations. From 1922 to 1925 he taught at Dartmouth College and from 1927 to 1964 he was a professor at the University of Wisconsin – Madison . From 1942 to 1952 he was there in front of the mathematics faculty. He directed the Army Mathematics Research Center at the university. His successor in this position was John Barkley Rosser .
He dealt with boundary value problems and asymptotic solutions of ordinary differential equations and also with inverse problems, for example from geophysics.
From 1949 to 1950 he was President of the Mathematical Association of America . In 1959 he was elected to the American Academy of Arts and Sciences . In 1964 he received the US Army's Outstanding Civilian Service Medal . He also worked on Birkhoff's book Relativity and Modern Physics (1923).
