Scouting report

Wrote what is generally considered the first assembly language, for the ARC2 and later APE(X)C machines at Birkbeck, and the assembler to go with it. Co-wrote some of the earliest books on how to program and design these machines, and did early work applying neural network ideas to character recognition in the late 1950s.

Curator’s note
