Hehehe, what a fight between Pro Riddlers!
And I must give the victory to... Paul!
It's indeed Yakov Dzhugasvili, son of Josef, the Man of Steel.
Sorry Phylo... Stalin's brother: no!, Stalin's relative: yes!, Stalin's son: yes! The name of the Son...?
Here's some other photographs (all from http://www.corbis.com
). Apparently the US held information about Jakob's death secret until the late sixties... The last picture showing the supposed corpse after being murdered or commited suicide "by guard". There is also rumoured that the germans tried to prison exchange Stalin's son against GFM Friedrich Paulus after the defeat at Stalingrad but that Stalin refused with the words "why change a soldier with a Field Marschall"...
Your turn Paul,
