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.).
