Harold E. Edgerton
Returned Sept. 11 by air plane (Air France) from Paris with Bill. The story of our summer adventures with underwater photography of the bottom of the sea was written in a series of 20 letters which were sent to the Nat. Geo. Society.
Three methods were used to take photos of the bottom:
(1) the Bathyscaphe, where an observer “shoots” the photo at the right time
(2) the Sled where the camera is towed along on the bottom.
(3) The vertical camera with a sonar indicator to tell when the camera is near the bottom.
All three methods were used during the summer.
[in left-hand margin:
The April 1955 Nat Geo Magazine had an article about the camera work.
Bill and I lived in the Toulon Navy Yard for the month of July on the Calypso, while working on the Bathyscaphe. Then we went to Marseille and Tunisia and return with a group of biologists.
