Dad at Work

Part of the Laboratory staff photographed during lunch break outside the laboratories in January 1947; the photograph bears this date on the back. 
Back row: Alf James, Clive Lawson, Norman Dales.
Front row: Harry Grange, Donald Pell, Nancy Rudham, John Donavon, Elizabeth Ferrer, George Allison, Audrey Keen (later Dales). Harry Grange apparently set the camera up to take a time release exposure and then joined the group.
