S. Joseph Begun

Born 2 Dec 1905; died 5 Jan 1995 at age 89.Semi Joseph Begun was a German-American inventor who built the first tape recorder for broadcasting (1934), which was later used in the 1936 Olympics. After WW II, he continued to work on magnetic recording media based on coating paper and plastic tape with ferromagnetic powder suspensions. Begun developed the first consumer tape recorder in the U.S. under the trade name Sound Mirror. He also negotiated the first sourcing agreement for magnetic tape with 3M - which became a major product line. He also invented the Mail-A-Voice, which magnetically recorded on one side of a paper disk for letter correspondence.
