This original contribution largely based on unpublished material to the biography of an American president and to the diplomatic history of the United States traces Franklin Roosevelt's contacts with the French from his childhood until the end of his life. It necessarily concentrates on the years after he ascended the presidency--the pre-war years of the 1930s and the war years from 1939 to 1944. Especially knotty were the war years when Roosevelt had to deal with two French governments--the Vichy government and the Free French government of Charles de Gaulle--as well as their representatives and supporters.
