# Hermann Bauer

Hermann Bauer (22 July 1875 – 11 February 1958) was a German naval officer who served as commander of the U-boat forces of the Kaiserliche Marine during World War I. In addition to his World War I career, Bauer is well known as the author of the book Das Unterseeboot, a treatise on the design and operation of U-boats, which was later translated into English by Hyman G. Rickover. Rickover's translation became a basic text for the US submarine service.
