Catalog Number





The Henry S. Tropp papers consist of materials stored in his office at Humboldt State University ranging in date from 1950 to 2000. The collection includes correspondence, research, and computer books, covering his professional work as both a history of computing scholar and a professor of mathematics.

Much of the collection relates to the work he did with professional associations such as AFIPS and ACM pertaining to publications and events about computer history. For example, the collection includes information about book reviews that he wrote for the IEEE Annals of the History of Computing, preparations for conferences such as HOPL (History of Programming Languages) and DPMA (Data Processing Management Association), and planning for events like Pioneer Day sponsored by the AFIPS History of Computing Committee. This portion of the collection is primarily composed of correspondence and memos. The collection also includes research for articles and events about important people, machines, and moments in computing history. Throughout the Tropp papers, there is correspondence with notable figures in the computing and computer history industry, some of which pertains to the Computer Oral History collection at the Smithsonian Institution. Finally, the collection holds information related to Tropp’s work as a professor of mathematics and his involvement in the field through professional associations and publications.

In addition to paper documents, the collection includes approximately 170 cassette tapes, five beta cam tapes, two VHS tapes, ten reel to reel tapes, and two DVDs. Most of these are either recordings of events, lectures, panel discussions, or oral history interviews. The collection also includes a small amount of photographic prints and slides.
