In the year that Winston Churchill announced Britain had an atomic bomb and the concept for the integrated circuit, the basis for all modern computers, was first published by Geoffrey W.A. Dummer, this photo was taken in Buckinghamshire. It was February 1952 and shows a group of approximately 70 men standing and sitting outside a wooden building. One, wearing a top hat in the second row, is holding a ukulele. Do you know where this location is? Do you recognise any of the men? Perhaps you can spot your grandfather, dad or uncle?
