Correspondence; reports; printed matter; memoranda; grant proposals; drafts of articles; speeches; minutes of meetings. The records of Hutchisson, director of the American Institute of Physics (AIP) (1957-1964) are primarily from his tenure as director, a period of enormous growth at the AIP with the initiation of the Education Department, the history of physics project, the Documentation Research Project, and a major increase in journal publication, particularly Soviet translation journals. The collection focuses on the areas of Hutchisson's particular interests: science education including various projects to improve physics teaching at all levels and increase the public understanding of physics; physics history including the creation of the Niels Bohr Library; journal publication including internal examination of publishing procedures at AIP, and an evaluation of SCIENCE ABSTRACTS. The largest series reflects Hutchisson's activities in the scientific community at large with correspondence discussing educational and scientific legislation and funding, and international cooperation on scientific matters. Other material concerns AIP awards, organizational structure and operations with coverage of the revision of the constitution and bylaws to create associate member society status and of the physical expansion at the new headquarters; public relations activities with press releases and files on seminars for science writers; the development of citation indexing; and the placement of physics graduates. Files of the Member Societies: Acoustical Society of America, American Association of Physics Teachers (AAPT), American Physical Society (APS), Optical Society of America, and Society of Rheology, are mostly informational copies, although the APS and AAPT files contain some substantive correspondence. Also contains speeches, reprints, personal correspondence, and correspondence concerning Hutchisson's involvement with the AIP in capacities other than director. Correspondents include: Henry A.
