John Stone Stone

John Stone Stone (September 24, 1869May 20, 1943) was an American mathematician, physicist and inventor. He labored as an early telephone engineer, was influential in developing wireless communication technology, and holds dozens of key patents in the field of "space telegraphy".

Career

Stone was born in Manakin village, Virginia, the son of Charles Pomeroy Stone, the American Civil War general and engineer. Raised in Cairo, Egypt until 1882, Stone was fluent in Arabic, French, and English; his father tutored him in mathematics. Stone also learned to ride in Egypt and was an excellent horseman. On his family's return to the United States, Stone attended Columbia Prep, Columbia University, and Johns Hopkins University.

After early research at American Telegraph & Telephone, Stone created his own company to build transmitting stations for the U.S. Navy. In 1907, Stone started in Boston the Society of Wireless Telegraph Engineers (SWTE). He won the Franklin Institute Edward Longstreth Medal in 1913. J. S. Stone invented the Stone common battery system. J. S. Stone help create the carrier current system of transmission. J. S. Stone's tuned circuits for radio transmitters and receivers had precedence over Guglielmo Marconi's similar system.

Among his political and Americanist activities was as a member of the American Defense Society's Board of Trustees.

Once married and divorced, Stone died in San Diego, California May 20, 1943.
