• He was awarded a full scholarship to Oxford University (Exeter College),
where he initially studied chemistry.
• Despite the fact that he was eligible for a deferment because of his studies—
he volunteered for active duty and became a flight lieutenant in the Royal Air
Force Coastal Command, flying Sunderlands.
• After the war he returned to Oxford to complete his studies, switching to
mathematics and obtaining his degree in 1948.

WORK• After a brief period with Macy’s in New York City, working as a sales clerk in the men’s sportswear
department, Codd found a job as a mathematics lecturer at the University of Tennessee in Knoxville,
where he taught for six months.
• Codd’s computing career began in 1949, when he joined IBM in New York City as a programming mathematician, developing programs for the Selective Sequence Electronic Calculator(SSEC).
• The SSEC was IBM’s first electromechanical computer. It was a huge and noisy vacuum tube machine.
• He also lived in Washington DC for a brief period, where he worked on IBM’s Card Programmed Electronic Calculator.
• In the early 1950s, he became involved in the design and development of IBM’s 701 computer.
• The 701 was originally known as the Defense Calculator. It was IBM’s first commercially available computer for scientific processing; it was announced in 1952 and formally unveiled in 1953.

• In 1953, Codd left the U.S. and IBM in protest against Senator Joseph McCarthy’s witch-
hunting and moved to Ottawa, Canada, where he ran the data processing department for
Computing Devices of Canada Limited.
• This department was involved in the development of the Canadian guided missile program.
• A chance meeting with his old IBM manager led to his return to the U.S. in 1957, when he
rejoined IBM.
• He worked on the design of STRETCH.
• STRETCH was the IBM 7030, which subsequently led to IBM’s 7090 mainframe technology.
• He led the team that developed the world’s first multiprogramming system.
• In 1961, on an IBM scholarship, he moved to Ann Arbor, Michigan, where he attended the
University of Michigan and obtained an M.Sc. and Ph.D. in communication sciences (1965).
His thesis—which was published by Academic Press in 1968 under the title Cellular Automata
—represented a continuation and simplification of von Neumann’s work on self-reproducing
automata.
• In it, Codd showed that the 29 states required by von Neumann’s scheme could be reduced to just eight.
