Working for many years as a mathematician for I.B.M., Mr. Bauer-Mengelberg also held simultaneous careers as a conductor and teacher. Before serving as President of Mannes from 1966-69, he was an assistant conductor at the New York Philharmonic under Leonard Bernstein and the music director of the St. Louis Philharmonic Orchestra. His overlapping expertise in computers led him to devise a system of musical notation for computers.

Born in Heidelberg, Germany, his family moved to the United States when he was 12. After serving in the Army from 1946-47, Mr. Bauer-Mengelberg attended New York University where he received a Bachelor's degree in philosophy and a master's in mathematics. Later he taught both subjects at a number of schools, including the New School for Social Research and Hunter College.
