John Robinson Pierce (March 27, 1910 – April 2, 2002), was an American engineer and author. He did extensive work concerning radio communication, microwave technology, computer music, psychoacoustics, and science fiction. Additionally to his professional career he wrote science fiction for many years using the names John Pierce, John R. Pierce, and J. J. Coupling. Born in Des Moines, Iowa, he earned his PhD from Caltech, and died in Sunnyvale, California, from complications of Parkinson's Disease. At Bell Labs Pierce wrote about electronics and information theory, and developed jointly the concept of pulse-code modulation (PCM) with his Bell Laboratories colleagues Bernard M. Oliver and Claude Shannon. He supervised the Bell Labs team which built the first transistor, and at the request of one of them, Walter Brattain, invented the term transistor; he recalled: Pierce's early work at Bell Labs concerned vacuum tubes of all sorts. During World War II he discovered the work of Rudolf Kompfner in a British radar laboratory, where Kompfner had invented the traveling-wave tube; Pierce worked out the mathematics for this broadband amplifier device, and wrote a book about it, after hiring Kompfner for Bell Labs. He later recounted that "Rudy Kompfner invented the traveling-wave tube, but I discovered it." According to Kompfner's book, the statement "Rudi invented the traveling-wave tube, and John discovered it" was due to Dr. Eugene G. Fubini, quoted in The New Yorker "Profile" on Pierce, September 21, 1963. Pierce is widely credited for saying "Nature abhors a vacuum tube", but Pierce attributed that quip to Myron Glass. Others say that quip was "commonly heard at the Bell Laboratories prior to the invention of the transistor". Other famous Pierce quips are "Funding artificial intelligence is real stupidity", "I thought of it the first time I saw it", and "After growing wildly for years, the field of computing appears to be reaching its infancy." The National Inventors Hall of Fame has honored Bernard M. Oliver and Claude Shannon as the inventors of PCM, as described in 'Communication System Employing Pulse Code Modulation,' filed in 1946 and 1952, granted in 1956. Another patent by the same title was filed by John Pierce in 1945, and issued in 1948: . The three of them published "The Philosophy of PCM" in 1948. Pierce did significant research involving satellites, including an important role as executive director of Bell's Research-Communications Principles Division) for the development of the first
