Hermann Chitz's life, which began quietly in 1908 in the Kingdom of Saxony, was to span a century and two continents. He escaped to America from Hitler's Europe; his parents, assimilated Jews, stayed behind. With a Prague doctorate and patent in hand, he landed in New York in 1939, and changed his name--starting over as Herman Sheets. In wartime he worked on critical aspects of the atomic bomb that would end the Second World War. In peacetime he directed research and development for Electric Boat's nuclear submarine program. At the peak of his career, in a single year, his wife died unexpectedly and he was fired for displeasing Admiral Hyman Rickover. As a single parent, with three of his six children still at home, he started his career over again in the University of Rhode Island. Not until his own children were educated and launched did he remarry and take on an expanded family. This is the remarkable story of an immigrant, inventor, ocean engineer, technical consultant, and family man who consistently turned difficult transition into new beginnings.
