In 1944 Stimson asked Rudolph Winnacker to undertake a study. of the Office of the Secretary of War during World War II. Winnacker was given access to the Secretary's files as well as to the Stimson diary. In April, 1945, Winnacker began submitting drafts of chapters to Stimson. Work on the study bogged down in May, 1946 with only two of the three projected parts completed. These covered the office through 1943. Little more of the study was ever sent to Stimson, and none of it, so far as can be determined, was published.
