A memorandum in the Silvermaster file from FBI Director [[J. Edgar Hoover]] to the Admiral Inglis of the [[Office of Naval Intelligence]] (ONI) dated 1947 informs ONI Stephan Brunauer had been investigated under the Atomic Energy Act upon recquest of the Atomic Energy Commission (AEC) in March of 1947 and upon reciept of the completed results from the FBI & Navy of the investigation by the AEC Brunauer had been denied access to restricted data under the Atomic Energy Act.
Hoover further advised that if the investigation of Brunauer had been continued it would have involved a violation of the Delimitiation Agreement in that Brunauer was a civilian. The investigation and its conclusions were conducted prior to a new Executive order on Loyalty of Government Employees and the FBI understood the Department of the Navy was also conducting its own investigation of Brunauer. <ref>FBI Silvermaster file [http://education-research.org/PDFs/Silvermaster134.pdf Vol. 134 November—December 1947, pgs. 66-67].</ref>
