Berkeley, Edmund Callis.

Edmund Callis Berkeley received a BA in mathematics and logic from Harvard University in 1930 after which he worked for Mutual Life Insurance of New York as an actuarial clerk. In 1934 he took a position with Prudential Insurance of America where he eventually became chief research consultant. He joined the U. S. Navy in 1942 and worked at Dahlgren Laboratory as a mathematician. There, he was assigned to Howard Aiken's Harvard Laboratory to work on the sequential calculator project (Mark II).

After leaving the Navy in 1946 he returned to Prudential. In 1947 he helped found the Eastern Association for Computing Machinery, renamed the Association for Computing Machinery in 1948, and served as its first secretary. At Prudential Insurance, Berkeley worked on a hazards project to identify the greatest modern hazards, and the research convinced Berkeley that nuclear war was the greatest hazard facing mankind. Prudential decided to abandon the project, and forbade Berkeley from working on it even on his own time for fear that it would reflect poorly on the company.
