Alan M. Turing
Abstract: This chapter presents Alan M. Turing's report, ‘Proposed Electronic Calculator’. The report was submitted to the Executive Committee of the National Physical Laboratory in February 1946, under the description ‘Report by Dr. A. M. Turing on Proposals for the Development of an Automatic Computing Engine (ACE)’. The design set out in ‘Proposed Electronic Calculator’ was the basis for all the ACE computers.

Keywords: Alan M. Turing, calculator, National Physics Laboratory, ACE computer,
