Editing Cray (section)

===Background: 1950–1972===
In 1950, [[Seymour Cray]] began working in the computing field when he joined [[Engineering Research Associates]] (ERA) in [[Saint Paul, Minnesota]]. There, he helped to create the [[ERA 1103]]. ERA eventually became part of [[UNIVAC]], and began to be phased out.

In 1960, he left the company, a few years after former ERA employees set up [[Control Data Corporation]] (CDC). He initially worked out of the CDC headquarters in Minneapolis, but grew upset by constant interruptions by managers. He eventually set up a lab in his hometown of [[Chippewa Falls, Wisconsin]], about 85 miles to the east. Cray had a string of successes at CDC, including the [[CDC 6600]] and [[CDC 7600]].
