Lyndon B. Johnson
Lyndon B. Johnson in his naval uniform from World War II, in a photo from 1942. Johnson was already a Congressman when the war started in 1941; he served very briefly as a lieutenant commander in the South Pacific before President Franklin Roosevelt called all members of Congress to return to their legislative work.
