Original deposit: The papers are extensive, covering all aspects of Strachey's life and career. They include much manuscript material documenting his contributions to computer design and programming (on Elliot, Ferranti and EMI machines), and to programming languages, principally CPL, devised for the Titan (Atlas 2) computer at Cambridge University. There are reports and research papers for many firms and companies engaged in computer manufacture, drawn up by Strachey as a consultant; papers relating to his service on official and professional committees, and reports on research projects; drafts for unpublished or uncompleted publications; lectures and correspondence. There are also some programs, reports, etc. emanating from firms or manufacturers, which are of interest in the early history of British involvement in the computer industry.
Supplementary deposit: The material was assembled by Dr Campbell-Kelly, while preparing his biographical note 'Christopher Strachey, 1916-1975', Annals of the History of Computing, 7, 1985, 19-42. It supplements the main collection of Strachey's papers and correspondence deposited in the Bodleian Library in 1980. The new material includes reminiscences from a number of friends, conference papers and articles by Strachey, and obituaries and other biographical material.
