Biographical/Historical note

Semi Joseph Begun, a pioneer in magnetic recording, was born in the Free City of Danzig (now Gdansk, Poland) on December 2, 1905. He earned an M.S. in Engineering in 1929 and a doctorate in 1933 from the Institute of Technology in Berlin for work related to magnetic recording. In 1929, he began working for Schuchhardt A.G., where he designed the first commercially successful magnetic recorder. Later, he worked for Echophon A.G. and C. Lorenz A.G., where he designed the first magnetic tape recorder for use by the German Broadcasting System. Begun emigrated to America in 1935 and worked in New York City both for the Guided Radio Corporation and independently. He and Sidney Wolf formed two companies Acoustic Consultants and Magnetone, a holding company for Begun’s patents. In 1938, he joined the Brush Development Company in Cleveland, Ohio. During World War II, Begun served as a member of the National Defense Research Committee. After the war, he wrote Magnetic Recording (1949), the first textbook on the subject. In 1952, the Brush Development Company merged with the Cleveland Graphite Bronze Company to form the Clevite Corporation. Begun held several executive positions at Clevite, including Director of Advanced Development and Vice President for International Operations. He was a member of Clevite’s Board of Directors and assisted in the merger between Clevite and Gould National Battery in 1968. In 1969, Begun formed Science Management, Inc., (SMI) to serve investment groups and other interested clients with the evaluation of new and existing products and to appraise management ability of new ventures with high technology products. In 1971, Begun founded Auctor Associates, Inc., a consulting firm focused on high technology markets. In 1983, he founded the Society for Prevention of Violence, a non-profit educational organization. Begun held over 50 patents and was the recipient of numerous professional awards. He died in Cleveland on January 5, 1995.

Scope and Contents note

The S. Joseph Begun papers contain correspondence, memoranda, patents, printed matter, reports, speeches and writings, awards, biographical materials, and autobiographical and historical material documenting the life and career of S. Joseph Begun.

Series 1: Personal Papers, 1927-1998, is arranged alphabetically by general subject and contains materials related to Begun’s education, biographical files and obituaries, and awards.

Series 2: Professional Files, 1924-1992, is organized in general chronological order. Following broad subdivisions covering his early activities in Germany and America, these materials are grouped by corporate affiliation: Brush, the National Defense Research Committee, Clevite, Gould, Science and Management, Inc., and Auctor Associates, Inc. It should be noted that Begun’s involvement with various organizations often overlaps; his continuous employment with Brush, Clevite, and Gould means that similar letterheads may be found under different corporate bodies.

Series 3: Writings and Speeches, 1930-1988, documents Begun’s publications and presentations, and includes drafts, correspondence, programs, printed matter, magazines, and reprints. It should be stressed that this series is not a bibliography. The series is arranged chronologically.

Series 4: Autobiographical and Historical Materials, 1888, 1930-2000, reflects Begun’s efforts in his last years to write his autobiography. He wrote drafts, interviewed former co-workers such as Al Dank and Otto Kornei from the Brush Development Company, and accumulated a considerable number of articles and other materials on the history of magnetic recording. Additional materials include a copy of Begun’s autobiography, My Years in Magnetic Recording: Dr. Semi Joseph Begun, as edited by Dr. Mark Clark.
