| Notes | At Donovan’s urging, in 1941 President Roosevelt established the Coordinator of Information, which included a propaganda organization — the Foreign Information Service (FIS). However, Donovan and FIS Director Robert Sherwood disagreed over propaganda messages and little was accomplished. When the OSS was created in 1942, FIS separated and became the Office of War Information. Free from arguments over propaganda content, Donovan formed the Morale Operations (MO) Branch on March 3, 1943. |
