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.
Today more than ever computers have taken center stage in our lives: science, economy, politics, art, there is no single human endeavour that has been left unaffected by Information Technologies. Whether this impact is positive or negative, is still very much up for debate. Continue reading “CfP: HaPoC 2019 in Bergamo”

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”
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. Continue reading “Validity and Correctness in LEO I & II”
The problem of identity is a long-standing one in philosophy. In turn, it is a crucial one for the Philosophy of Computer Science, and in particular for answering the question ‘what is a program?’. Two major strands in the history of such conceptual investigation can be found. Continue reading “Reflections on Identity and Copy of Programs”

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””
Submission of two-page extended abstracts (including footnotes, but excluding references) are invited. Accepted papers will be given a 30 minute presentation slot including discussion. We intend to publish selected papers in a special journal issue following the symposium.
