Alison & Adrian Bryant

Control Data Corporation was incorporated on July 8, 1957 in Minneapolis, Minnesota. CDC grew rapidly, eventually becoming the largest computer company in Minnesota by number of employees and annual revenues. The company produced some of the fastest computers of the time, including the CDC 6600, designed by Seymour Cray and generally considered the first supercomputer. In 1992, Control Data Corporation ceased operations and was split into two companies: Ceridian Corporation and Control Data Systems Inc.
In 1962 E. L Heymanson & Co. Pty Ltd. established representation for Control Data Corporation computer systems in Australia effective January 1st. This site is for ex employees of Control Data Australia (CDA) and Control Data New Zealand (CDNZ) and the Australasian (AAR) region.
