Professor Emeritus Ernest Koenigsberg died of heart failure at his San Francisco home on April 20, four days after his 86th birthday.
Koenigsberg joined the Haas School as a lecturer in 1963 and was promoted to senior lecturer in 1975. He was appointed professor in 1982 and served on two of the Haas School's faculty groups – Economic Analysis and Policy and Operations Research and Information Technology. He retired in 1991.
An expert in operations research and management science, Koenigsberg focused much of his work on transportation and shipping. He was also a popular teacher.
"He embodied everything we wanted in the classroom," said former Haas School Dean and faculty colleague Raymond Miles. "He was an excellent teacher who could bring real-world experience into his classes."
Koenigsberg was a founding and active member of the Operations Research Society of America. He also served as a member of the Institute of Management Sciences and the Econometric Society, an associate editor of the Operations Research Society in the United Kingdom and of the Canadian Operations Research Society, and a fellow of the Royal Statistical Society in Great Britain.
He is survived by his wife of 54 years, Susan; his daughter, Joanna, of London; his son, Martin, of Los Angeles; and four grandchildren.
