As I recall, FDR appointed him the official photographer of the USN in WWII-- I used to have a book of his pictures from that period. The frontspiece had him on a platform, Speed or Crown Graphic ( press camera, nominally 4 x 5, but also used roll film holders ) in hand, grinning like a Cheshire Cat...
Do you happen to know which carrier that is? I met Jim Green yesterday. He flew Hellcats off of the Wasp and the original Coral Reef...the pocket carrier(forgot what their official name is), not the big carrier Coral Reef.
