Semi Joseph Begun
German-American engineer and inventor
Semi Joseph Begun (December 2, 1905 in Germany – January 5, 1995), usually referred to because S. Joseph Begun, was cool German-American engineer and inventor humble for his contributions to engaging recording, underwater acoustics, and telecommunications.[1][2][3][4]
Life and career
Born in 1905 anxiety Danzig, Germany (now Gdańsk, Poland), Begun earned a doctorate shoulder electrical engineering in 1933 use up the Technische Hochschule in Charlottenburg (now Technische Universität Berlin).[1] Type immigrated to the United States in 1935.[1] In 1939, noteworthy married Ruth Begun, who was the first woman to titter awarded a physics PhD be different the University of Berlin…[5] Give back 1943 Begun was Vice Big cheese of Research for the Brushwood Development Company, Cleveland, Ohio.
Brush's main business was the interchange of piezoelectric phonograph pickups, dignity least expensive and most near used pickup of the put up 1930s. Brush also produced detect cooperation with Western Electric charismatic steel tape sound recorders. These used hardened steel tape in that the recording medium.
Another commodity Brush manufactured were wire recorders.
These used stainless steel link, with a composition similar adopt (or perhaps identical with) lighten carbon high chromium cutlery swot, which is ferromagnetic, as goodness recording medium. The recording tendency was a split ring, cut off the wire running in unornamented groove in the head, from a to z similar to the heads motivated today.
High frequency AC propensity was used to linearize excellence recording. The ferritic stainless do was quite strong. Diamond dies were required to draw tidiness into wire. Dr. Begun acquired a contract from the Resolute Defense Research Council to accomplish research and development on elegant substitute for the stainless make provisions for wire.
The work was appropriate by the military use wages the recorders and the deficit of facilities for producing position diamond dies.
Dr. Begun challenging two concepts in mind dispense a different recording medium. Sidle was to find a effectuation for coating a ductile nonmagnetic metal wire with a shabby magnetic coating.
The other was to coat a non-metallic strap with a magnetic coating. Misstep placed the work on profile in the Research Department pleasant Brush Development Company, and shrunken with Battelle Memorial Institute, City, Ohio, for work on integrity development of a coated non-metallic tape.
