Biographical Note

Hyman Joseph Ettlinger was born September 1, l889, in St. Louis, Missouri, and was educated at Washington University (Bachelor's degree, 1910) and Harvard University (Master's, 1911; Ph.D., 1920). He joined the faculty of the University of Texas at Austin (UT) in 1913, and retired in 1968. He was especially noted for his teaching. Ettlinger's research was in differential equations and the calculus of variations. He was associated with the UT Defense Research Laboratory, where he worked on aerodynamics. He was chairman of the Department of Pure Mathematics for approximately 25 years. He died in Austin on June 8, 1986.

Scope and Contents

Records of Ettlinger's teaching (1925-1966; 8 in.) include teaching notes and mimeographed text materials for several courses. Notes of courses Ettlinger attended while a graduate student at Harvard University are present (1910-1913; 7 in.) and include notes of courses by G.D. Birkhoff, M. Bocher, C.L. Bouton, W.E. Byerly, J.L. Coolidge, H.N. Davis, D. Jackson, W.F. Osgood, and B.O. Peirce. There are mimeographed notes of lectures on Heaviside's operational calculus given at the Massachusetts Institute of Technology (1925; 2 in.). Ettlinger's research is represented by notes and technical reports prepared in association with the UT Defense Research Laboratory (now the Applied Research Laboratories) (1947-52; 4 in.). Also included is a computer printout (1977; 84 pp.) and associated letters and notes on the doctoral descendents of UT mathematics faculty (prepared in collaboration with Albert C. Lewis). There is a small amount of general correspondence (1912-81; 2 in.).
