So this photo of the Cavendish Laboratory is from 1939, and I was wondering if anyone knew any more about who was in the photo. (Click to enlarge)
From notes I've been given, I believe the front row is:
DE Lea?; Unknown; ME Oliphant; Norman Feather; GFC Searle; Bragg Jr; John Cockroft; Philip Dee; James Chadwick or CTR Wilson? Miss Davies; Unknown
The second row definitely has Sam Devons (5th from left; dark shirt), and there's some suggestion that the man to his left (i.e. 4th from left on 2nd row) is Hermann Bondi; Eric Wild is in the 3rd row (4th from left)
Edit: Context of the photo. I don't know anything more about why it was taken other than it being the yearly (1939) photo of the department's Faculty Staff and Graduates; a family member has inherited it as his father is in it.
Any help, contributions or suggestions appreciated!
Thank you.
