I imagine that my dad's (Philip Rosten-Rosenblum) contribution to laser communication will be lost to history for lack of documentation. While he had been hired by TRW for the X ray satellites, when those had been launched, they had him work on a new kind of idea--laser communication. That is the same thing as radio waves except that you super impose signals on lasers instead of radio waves. That was very well known to me who first hand knowledge of his lab at TRW and his associates. However when TRW went under because of the KGB spy that had been found there, all documentation was lost and they sold their records to other aerospace corporations. In the mix up, my dad's name was lost. But I imagine that is no worse than the inventor of fire or the wheel whom we also do not know their names. [And by the way, it had nothing to do with the amazing advantages of laser communication as we see in fiber optics and the Space X laser communication system, but rather to have a signal system between satellites that the Soviets could not eavesdrop into.] That was at the height of the Cold War when the USSR and the USA were almost at the point of total war. Some system to protect American communications had to be found and that was my dad's idea. A way to have a system of communication that the Soviets could not listen into. Radio waves are spread out. Laser signals are focused. {TRW had noticed him because they wanted X ray satellites,-- and who better to get for that than the inventor of the Infra Red ray Telescope and later invented the Copy Mate Machine using X rays to for a perfect image.. Only after the last of those satellites were launched did the focus switch to laser communication.
