On the 25th October, 2018, the Leo Computers Society held a celebratory lunch to mark the 90th birthday of Ralph and Frank Land, two of the most active members in the Society.
Frank Land became a programmer for LEO in 1952; later was appointed Chief Consultant for LEO Computers and its successors. He is Emeritus Professor of Information Systems at the London School of Economics.
Ralph Land joined LEO Computers in 1959; he was appointed General Manager for Eastern Europe for English Electric and, later, ICL. He was appointed a CBE “for services for export” in 1996.

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”
Mary Lee Woods Berners-Lee (1924-2017) was a British mathematician and computer scientist. After graduating at the University of Birmingham, she got a fellowship at the Mount Stromlo Observatory in Canberra. Back from Australia, in 1951 she started working for Ferranti as a programmer, in the Ferranti Mark I and I* team at the University of Manchester.
It is a pleasure to announce the start of the ANR project What is a (computer) program? with a two days event to be held on February 7-8 at MESH, rooms 1 and 2, Espace Baïetto, 2 Rue des Canonniers, Lille.
On February 7th, there will be a session of the Lille-Paris séminaire History and Philosophy of Computer Science and Computing (HEPIC) with participation of Cliff Jones and Samuel Goyet (see here for more details). On February 8th, there will be the workshop Models between structures and meanings of programs which introduces the project followed by several talks from members of the project. Continue reading “Launch of ANR project: What is a program?”
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”
Philosophy, like other disciplines in the humanities, enjoys a mutually enlightening relationship with history […] The philosophy of computer science, like other philosophy devoted to a particular subject, enjoys a mutually enlightening relationship with the history of that particular subject […] I have been pleasantly surprised to find research in the history of computing quite interesting, and can only hope for reciprocal generosity toward philosophy on the part of historians. With respect to computing, the international organization founded to bring together history and philosophy is HaPoC, the Commission on the History and Philosophy of Computing. Designated a Commission by both divisions of the International Union of History and Philosophy of Science and Technology (http://www.iuhpst.org), it aims to “enhance our understanding of computing by means of historical and philosophical explorations.” The dedicated and hard-working HaPoC leaders Liesbeth de Mol, of the Université de Lille, and Giuseppe Primiero, of Middlesex University London, explain how this came about.
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.
