As an enthusiast of vacuum tube radio technology, with its smells of hot dust and pipe tobacco, I found the story of the Lyons Electronic Office to be a superb metaphor for the British approach to engineering - uncertain, incremental, cautious, yet with flashes of great brilliance.
John Simmons and his team knew they were far ahead of everyone else (just as, earlier, at Bletchley Park, Thomas Flowers and Alan Turing must have known the same about their 'Colossus' machine) and we see that the dedication and enthusiasm produced by that awareness led them to the very forefront of an emerging technology. In 2003, vacuum tubes and tanks of mercury must seem very 'Heath Robinson' to us, yet it is worth reflecting upon the vast distance the computing industry has travelled in the 50 years since LEO. For a vivid example of this journey - go to the Science Museum in London and take a look at the Ferranti 'Pegasus' machine on display as a contemporary of LEO.
Alas, the business world failed to capitalise on the opportunity and the subsequent mergers meant opportunity was lost.In fairness, the author does make the point that the mergers that led to the creation of ICL had to happen to make the industry, as a whole, stand any kind of chance against the huge US market. Despite this, the Americans were still able to achieve dominance.
This is a fascinating story, skilfully told to engage and capture the reader's attention. There are no heavy techie details and no long/boring corporate manifestos - just the plain simple story of the vision of those who saw an opportunity to advance their own view of the application of knowledge for the benefit of all.
