Alan Turing Proposal For 'ACE' Automatic Computing Engine

Alan Turing Presents the "Proposal for the Development in the Mathematics Division of an Automatic Computing Engine (ACE).”

This research proposal was presented to a meeting of the Executive Committee of the National Physical Laboratory (NPL) in Teddington, England, and approved at a second meeting held a month later.

Turing based this research on von Neumann’s First Draft of a Report on the EDVAC. He had studied it in summer 1945 when he was recruited by J.R. Womersley to join the staff of the NPL.
