John Herbert Orr (August 19, 1911 – May 6, 1984) was an Alabama entrepreneur who formed Orradio Industries, Inc., a high-technology firm that manufactured magnetic recording tape for both professional and consumer markets.
However, the tape had not been completely erased, and Hitler's voice, so the story goes, could be heard intermittently along with that of Eisenhower.
When the German engineers gave Orr their studies on plastic tape, the only place in Europe manufacturing the material was a factory making ladies imitation leather purses.
The system, called the "Orrtronic Tapette", was produced in versions for home, commercial, and automotive use, and was offered as a prize on television game shows.
OrrTronics was then sold to Delco Battery and Orr formed Orrox Corporation, which specialized in hard disc drive controllers, refurbishing of Quadruplex videotape recorder heads, and computerized video tape editing systems for TV broadcasters and post-production houses.
