This is the exciting history of the birth of computing. When a new field of knowledge opens up new possibilities, anything can happen---water computers, tea shops at the cutting edge of technology and, as often happens with technology, parallel development in separate parts of the word; Britain, the U.S., the U.S.S.R. and (a suprise to me) Australia.
This account is full of suprises about the earliest electronic computing machines, with colourful accounts of the pioneers in the field do amazing things that no-one had previously even thought of. A golden age of innovation, both technically and commercially with visionary business executives seeing the potential for the new technology---for example, Lyon's tea shops.
It is a fascinating history, which Mike Hally appears to relish. He avoids technical details of these early computers, but blends in enough information to appreciate the difficulties faced by the engineers who were, effectively, inventing the modern world. He also tackles the more controversial subject of priority of invention, which still rages today, without passing judgements but sticking to the facts.
It is hard to know what it must have been like in those exciting times, but Mike Hally captures a flavour of it in the interviews with some of those involved with these early machines, and one wonders if such a revolutionary step could ever now be taken in quite the same way.
A book not just for the student of computing history, but an accessible history of pioneering, vision and invention.
