Ed Posner

Edward Charles Posner (August 10, 1933 – June 15, 1993) was an American information theorist and neural network researcher. He became chief technologist at the Jet Propulsion Laboratory, and founded the Conference on Neural Information Processing Systems.

Education and career Posner was born on August 10, 1933, in Brooklyn, and graduated from Stuyvesant High School in 1950; at Stuyvesant, one of his close friends was mathematician Paul Cohen. While a graduate student, he also visited Bell Labs, and later claimed that he had been assigned to the desk there that had formerly been Harry Nyquist's. at only 26 pages long, it held the record for the shortest doctoral thesis at the university.

Posner's research in information theory and coding theory was applied in the design of the NASA Deep Space Network, used for the communications between spacecraft and their base stations on Earth. He also studied communications networks and cellular telephone switching systems,
