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.
