Egon Balas (Cluj, Romania, June 7, 1922) is an applied mathematician and a professor of industrial administration and applied mathematics at Carnegie Mellon University. Balas is the Thomas Lord Professor of Operations Research at Carnegie Mellon's Tepper School of Business. Balas did some of the fundamental work in developing integer and disjunctive programming.[1]
Life and education
Balas was born in Cluj (Romania) in a Hungarian Jewish family. His original name was Blatt, which was first changed to the Hungarian Balázs and then later to the Romanian Balaş. He left Romania in 1966 and accepted an appointment with the Carnegie Mellon University in 1967. Balas obtained a "Diploma Licentiate" in economics (Bolyai University, 1949) and Ph.D.s in economics (University of Brussels, 1967) and mathematics (University of Paris, 1968).[2]
