On the back of this photo of my dad and his father, his mother has written "Hamburg, NY, 1941, right after Pearl Harbor."
Here he is with his mother in a companion photo. He looks rather dressed up which makes me wonder if he had perhaps just enlisted.
I know he was gone off to the war in January as this telegram to his parents indicates: "Am in Norfolk on USS Long Island and feeling fine. Do not mention this to anyone when you answer my letters." All very "loose lips sink ships."
The USS Long Island was the first cargo ship to be converted to use as an aircraft carrier since we did not have enough warships after Pearl Harbor. They came to be known as "baby flat tops" as a result of their distinctive look. I have the 1943 Christmas Day Menu Card from that ship which my dad kept. You can read about it here.
