I recognise Dirac and Schrodinger only. Can you name others?
The woman is probably Marie Curie.
Is that Kapitsa ?
(2nd row, 4th from the left)
"Photograph taken in Dublin in 1942, and showing in the front row (left) theoretical physicist Dr Sheila Tinney with Nobel physicist Paul Dirac (3rd from left), Taoiseach Éamon de Valera (centre) and Prof Erwin Schrodinger (second from right)."
So not Kapitsa then, he would have been back in Russia by then.
Since the photo was taken in 1942 is sort of rules out most of the famous physicists of the time; they were either already working in Los Alamos, on the opposing side of the war (Heisenberg&co) or not able to travel for other obvious reasons (Kaptisa, Landau..).
BTW, I cheated. Dropped the image onto Google Images. Handy way to get information about an image.
Apart from Dirac, Schrodinger, and Irish Taoiseach (Prime Minister) de Valera, I also recognize Irish mathematician Dr. Arthur W. Conway (front row, 5th from left), who was also President of University College Dublin from 1940 to 1947, corresponding to the time this photo was taken.
Here is some biographical entries of him online:
Yes, I recognize Dirac and Schrödinger too.
Second row (from below), nr 3 from the left looks like Heisenberg, I think.
On this page, http://www-groups.dcs.st-and.ac.uk/history/Biographies/Tinney.html, the entire first row of the photo is described.
Eddington! Didn't he go crackers trying to reconcile religion and relativity?
Separate names with a comma.
