LEO editor

IN AT THE START OF BUSINESS COMPUTING 

  •  What was it really like to be in at the start of business computing, to attempt what no-one had done before, to develop totally new ways of processing and managing data that would eventually completely change the way business operates across the world?
  • A flavour of what it felt like can be had from the reminiscences of over 80 people who variously worked on LEO (Lyons Electronic Office), the world’s first computer to run business applications, and its successor machines, now being published as a book this month (28 September). Coming out strongly through the book, “LEO remembered,” is the shared excitement from those involved – designers, engineers, programmers, operators and sales people alike – in knowing that they were onto something big.
  • Noting this, the book’s joint editors, Hilary Caminer and Lisa McGerty, comment: “First hand testimony takes us to the heart of the day-to-day routine, the frustrating task of locating and mending hardware and software faults, the camaraderie built from working together on never-before-tackled systems and programming problems, the ethos that LEO instilled and that stayed with its people in their later, often very distinguished careers.”
  • LEO story 
  • The LEO story began in 1947 when the board of the large J. Lyons & Co catering group, then under the threat of being swamped by paperwork, stumped up the princely sum of £3000 (£83,000 in today’s money) to help fund the completion of Cambridge University’s large scientific computer known as EDSAC. Once it was working, Lyons adapted EDSAC to become LEO for the very different needs of business where relatively straightforward calculations, but in much larger volumes, were involved.
  • This was in no way a straightforward task. Frank Land, one of the ground-floor LEO pioneers, commented: “What is not generally appreciated, and is part of the remarkable story that unfolded, is that Lyons, famed for baking bread and feeding people, actually built the computer using their own resources on site at their Cadby Hall headquarters”.
  • The bold decision by the Lyons board bore fruit when, in November 1951, just over 70 years ago, the resulting LEO ran its first live business application, a bakeries valuation job, the first in the world to do so. Lyons retained this lead through most of the 1950s and early 1960s, setting up a company, LEO Computers Ltd, to develop and sell computers at home and overseas before eventually merging with International Computers and Tabulators (ICT) in a final fling for the British computer industry.
  • The LEO story ended in 1981 when the last of the LEO computers, a LEO 326, one of a large number operated by the Post Office for telephone billing, was finally turned off, the same year coincidentally when the last of the Joe Lyons famous teashops closed its doors.
  • ‘LEO remembered’ is published, with financial support from the AIT Trust, by the charities LEO Computers Society and the Centre for Computing History, based in Cambridge. It has a foreword by Dame Stephanie Shirley CH and an introduction by Professor Frank Land OBE.
  • The book is available, priced £8 plus postage, from LEOremembered@leo-computers.org.uk

1919-1997

Abstract: John Pinkerton joined Lyons as chief engineer at the very beginning of the LEO initiatve and led the engineering side until the merger with English Electric. He held senior engineering appointments within the merged companies until his retirement. Much of the success of the LEO enterprise lay in his genius for bringing innovative ideas to practical fruition – one of the true heroes of the information age.
