Description of Photograph Photograph (original print) of the LEO I power supply switchboard in the main installation area at Cadby Hall. Further power supply equipment was installed in the basement. The photograph was taken by Leo Fantl, one of the programmers in the original LEO team and also a keen amateur photographer. This image appears in the interactive plan for our Virtual LEO I installation, p27. The caption written on the back of the print is in LEO historian Peter Bird's handwriting, indicating the Fantl prints were originally from his collection but were at some point separated before they were given to the archive.
Research comments: This photograph of LEO's power distribution panels shows the calculator room at Cadby Hall before the false floor is laid. The windows to the left of the picture face the 'quad' area at the centre of WX (administration) block. The workbench near the windows gives a sense of the room as a laboratory and workshop as it was at this point in time i.e. before LEO I is fully operational.
