Jones, Capers (2014) ‘The Technical and Social History of Software Engineering’, Addison-Wesley. Capers Jones’s book is a monumental history of computers and computing with a prime focus on ‘software engineering’. Jones has an introductory chapter which deals with the pre-history from the beginning of civilisation to 1930, then chapters dealing with each decade up to 2013. His chapter on the 1950s includes the LEO story, brief (pages 85, 86, in a 452 page book), but giving some weight to the place of LEO in computing history. See Capers Jones
