**NEUGEBAUER, Otto** Eduard. Innsbruck 26.5.1899 — Princeton N.J. 19.2.1990. Austrian Historian of Astronomy and Mathematics in the U.S.A. Son of Rudolph N. In 1917 he left Akad. Gymnasium, Graz, to join the army and thus obtained his matriculation without examination in classical languages in which the mathematically and technically minded youth was not at all interested. After one year’s service in Italy he studied electrical engineering and physics at Graz in 1919-21 and at Munich 1921-22. Then studies of mathematics at Göttingen, learned Egyptian for his diss. there. Ph.D. 1926 Göttingen. In 1927-33 PD and Oberassistent at Math. Inst., then ao. Professor at Göttingen. Forced by the Nazis to leave Göttingen he emigrated to Denmark (in 1933-39 eo. Professor of Mathematics at Copenhagen) and later to the U.S.A. In 1939-49 Professor of Mathematics at Brown University, in 1949-69 Professor of History of Mathematics there. Married 1927 with Grete Bruck.

ON did important work in mathematics in general, but his specialty was the history of ancient (classical and Near Eastern) mathematics and astronomy. In addition to Greek and Egyptian he learned Akkadian. Delving deep into original sources he was often capable of opening entirely new lines of understanding and made many pioneer finds. He made extensive study on the history of Oriental science, including Indian, partly in collaboration with his student D. Pingree.
