Edward Ellsberg (1891-1983) graduated first in his class from the United States Naval Academy in 1914. After he did a stint aboard the USS Texas, the navy sent Ellsberg to Massachusetts Institute of Technology for postgraduate training in naval architecture. In 1925, he played a key role in the salvage of the sunken submarine USS S-51 and became the first naval officer to qualify as a deep-sea diver. Ellsberg later received the Distinguished Service Medal for his innovations and hard work.
Rear Admiral Ellsberg was awarded the C.B.E. by His Majesty King George VI, and two Legions of Merit by the United States Government.
