J. Robert Oppenheimer Personnel Hearings Transcripts

J. Robert Oppenheimer Personnel Hearings Transcripts

In December 1953, the Atomic Energy Commission (AEC) suspended the security clearance of Dr. J. Robert Oppenheimer, and after a four-week, closed-door hearing in April and May 1954, formally revoked that clearance. In June 1954, the AEC released a redacted version of the hearing transcript, (see AEC press release), with security classified information deleted, published by the Government Printing Office (GPO) under the title, In the Matter of J. Robert Oppenheimer: Transcript of Hearing before Personnel Security Board. Sixty years later, the Department of Energy has re-reviewed the original transcript and is making available to the public, for the first time, the full text of the transcript in its original form. The transcript, produced in 19 volumes, is arranged in such a way that pages from which information was deleted in the published version are easy to locate with the deleted information readily identifiable. Also included is a separate volume showing the location and text that was deleted from the 1954 published version. This volume gives the page number of both the 1954 GPO publication and the original transcript. See Oppenheimer transcripts.
