On 5th and 6th November 2001, an international conference was held at the Guildhall in London to mark the 50th anniversary of the world's first business application of a computer, and to honour the Leo pioneers of 1951.

The conference, sponsored by the Corporation of London and many leaders of the computing and telecomms industry, was a great success and many ex-Leo employees joined the conference in the evening of the first day for the 2nd John Pinkerton Lecture, given, appropriately, by David Caminer OBE, Systems & Programming Manager for Leo from 1949.
