Research comments: This is an interesting photo of some of the earliest LEO pathfinders. Derek Hemy was instrumental on the systems and programming side of LEO; Ernest Lenaerts, an engineer, had spent time at Cambridge developing the EDSAC machine so was involved in LEO right from the start; Leo Fantl worked alongside Derek Hemy as a pioneer programmer. Gordon Gibbs is the only person in the photo of whom we know little.

Another interesting aspect of this photo is the roll of paper that can be seen hanging (from the ceiling?) near the console. This is early in LEO's I career, the machine having successfully run its first program in 1951. So just what was that roll of paper used for? (LM)

Collected by Peter Bird as part of his research for his book LEO - The First Business Computer (1994).
