Scope and Content
Administrative / Biographical History
ICL was founded in 1968 under the Wilson Labour Government in the Industrial Expansion Act as part of its industrial rationalisation programme, in order to create an international presence in computers. The formation of ICL was the culmination of a series of mergers and acquisitions during the late 1950s and 1960s which brought together the two strands of punched-card equipment manufacturers and general electrical equipment manufacturers, both of which were diversifying into computers. The immediate merger brought together International Computers and Tabulators Ltd (ICT), and English Electric Computers. Later, Standard Telephones and Cables (STC) became the parent company.
