LEO Chronicle

Scope and Content

David Caminer's copy of the LEO Chronicle - a detailed timeline for the development of LEO written by TR Thompson. It covers first the period 1947-55, then Thompson added an extension for 1955-61.

This copy is evidently a photocopy of a version originally owned by Ernest Lenaerts - it includes some of his annotations.
