At the age of 90, Land, born Landsberger in Berlin, who came to England as a young boy fleeing Nazi Germany, expressed his delight at receiving the award which he sees as “a sign of recognition of the LEO contribution to information systems.” Continue reading “OBE for Frank Land”
The LEO Computers Society 2019 reunion was held on Sunday, 7th April 2019 at the Victory Services Club, Marble Arch. With an attendance of around 80 including some invited guests, the event gave members the opportunity of catching up with colleagues – some from as long ago as the 1950s, including at least half a dozen who had actually worked on LEO I, the world’s first business computer. The Society is in partnership with the Centre for Computing History, Cambridge (CCH), working together on a Heritage Lottery Funded (HLF) project to preserve, protect and promote LEO’s story.
Efficient and reliable computing is based on validity and correctness. Techniques to ensure these essential features have been in place since the early days of computing. The present study focuses on the hardware testing, data validation and program correctness techniques designed and implemented for LEO I and II machines in the UK during the 1950s.

Two case studies in the early European Computer Industry
A common pattern in the growth and development of early Western European computer manufacturers is the collaboration between academia and entrepreneurship. Very often early European computer companies established a joint venture with an academic environment – a university or a research institute. Continue reading “Business computing seminar in Lille”
The presentation is an historical reconstruction of the procedures to ensure validity and program correctness in the early examples of business computers: the focus of the talk is the hardware testing, data validation and program correctness techniques designed for LEO I and II in the UK during the 1950s.

Abstract of the paper presented at the 4th HaPoC – History and Philosophy of Computing conference in Brno, 3-7 October 2017.
Coping with the “American giants”: mergers, relationships and attempted partnerships in the European computer industry in the early Sixties
During the 1950s, a fragmented computer industry grew up in Europe. After the enthusiasm and pioneering in a brand new business like computers, at the beginning of the 1960s these companies were weakened by several issues, such as the financial crisis and the pressure of US competitors like IBM and General Electric. The investments in R&D were not fully refunded by the income from machines sales after several years. The growth of a computer company, in fact, was often doomed by these costs and very often also by lack of proper marketing experience in a totally brand new field. Continue reading “Coping with the “American giants””
Peter Bird worked for J. Lyons & Co. from 1964 to 1991. He published his book LEO: The First Business Computer in 1994 and later an extensive book about Lyons in 2000.
We met Peter Bird in October 2016 at his house in Wokingham. We had a productive day, discussing about his books on Lyons and LEO. A day full of hints and suggestions, going through his collection of photos of LEO people and machines. Peter passed away on the 16th August 2017. Continue reading “In memory of Peter Bird”
On November 29th 2016 we attended the unveiling of a commemorative plaque for LEO – Lyons Electronic Office. The plaque is located in Lyons Walk, W14 0QH, former location of Cadby Hall, the factory complex and the headquarters of J. Lyons & Co and LEO I’s home in Hammersmith.
The engraved stone has been generously funded by Tony Morgan, who was Commissioning Manager at LEO Computers Ltd. and is now Technical Consultant to the LEO Computers Society.
On November 29th, 2016 LEO Computer Society will unveil a plaque commemorating LEO I on the 65th anniversary of its first business routine run in Lyons Walk, Olympia, London. The location is close to the former location of Cadby Hall, the major office and factory complex in Hammersmith, London, which was the headquarters of J. Lyons & Co and LEO’s first home.
