This memorandum, dated May 27, 1953, and authored by H. Marshall Chadwell, the Assistant Director of Scientific Intelligence, formally assigns the responsibility for maintaining current knowledge regarding reports of unidentified flying objects to the Physics and Electronics Division of the Office of Scientific Intelligence (OSI). The document directs the Chief of the Physics and Electronics Division to assume this duty and requests that the Chief of the Applied Science Division provide necessary support from a weapons and hardware perspective. The memorandum notes that major files concerning U.F.O.s were previously located in the Air Branch of the Applied Science Division and the Operations Staff office. It identifies Mr. Jackson Hacker of the IPS as the current custodian of certain files that were transferred to the IPS from the O/CI. The Physics and Electronics Division is instructed to take custody of these relevant files and to coordinate with Mr. Hacker to ensure that future material on the subject is routed directly to the Physics and Electronics Division.
