From Wikipedia

John Robinson Pierce (March 27, 1910 – April 2, 2002), was an American electrical 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.
