Irving B. Kahn

Died 22 Jan 1994 at age 76 (born 30 Sep 1917).American inventor of the teleprompter, who headed the TelePrompTer company. In the mid 50's, Kahn designed and built what was perhaps the first remotely controlled, multi-image, rear projection system in the world for the U.S. Army's facility in Huntsville, Ala., to make persuasive presentations to visiting Congressmen. With five images (one large, 3¼ by 4 slide or film image in the center flanked smaller slides at each side) and random access it could search and select among 500 slides. TelePrompTer also made many technological contributions to the early cable TV industry. In 1961, Kahn and Hub Schlafley demonstrated Key TV, an early pay TV concept, by showing the second Patterson vs. Johansson heavyweight fight, essentially giving birth to pay-per-view.

Old man: "Well, son, I got married when I was 21. The wife and I decided that if we had arguments, the loser would take a long walk to get over being mad. I suppose I have been benefitted most by 79 years of fresh air."
