Nathan B. Stubblefield (November 22, 1860 - March 28, 1928) was an American inventor and Kentucky melon farmer. It has been claimed that Stubblefield invented the radio before either Nikola Tesla or Guglielmo Marconi, but his devices seem to have worked by audio frequency induction or audio frequency earth conduction [History of the Radio Industry in the United States to 1940] by Carole E. Scott, State University of West Georgia (creating disturbances in the near-field region) rather than by radio frequency radiation for radio transmission telecommunications. Though there were contemporaneous experiments by others such as William Preece, Stubblefield has been proposed as a claimant for the invention of wireless telephony, or wireless transmission of the human voice. The physics club of Murray State University is named in his honor.

Biography

Early years

Stubblefield was the second of seven sons (Walter Watt 6/27/59, James Franklin 10/25/62, Louis Shelly 6/27/64, Robert Reginald 11/26/65, William Victor 1/27/68 and Harry Lee 9/26/71) of a lawyer, William "Capt. Billy" Jefferson Stubblefield (1830-1874), and Victoria Bowman Stubblefield (died 1869). Stubblefield lived in Murray, Kentucky. He was orphaned in 1874. Stubblefield was tutored by a governess and later attended a boarding school called the "Male and Female Institute" in Farmington, until his father died.

Stubblefield was self-educated by reading whatever publications were available in Murray, such as The Scientific American and Electrical World. He married Ada Mae Buchannan in 1881. They had nine children, three of whom died in infancy. His son Bernard was his primary assistant in the wireless telephone experiments. From 1907 to 1911, Stubblefield operated a home school called "The Nathan Stubblefield Industrial School," or "Teléph-on-délgreen Industrial School" built on his 85 acre melon farmland.

Death and afterwards

Stubblefield later lived in a self-imposed isolation in a crude shelter near Almo, Kentucky and eventually, starved to death. Stubblefield destroyed every prototype he made. He was buried in the Bowman Cemetery in Murray, Kentucky (Calloway County).

Since his death, various individuals and groups in Murray, Kentucky have publicized Murray as the Birthplace of Radio, a claim which is not widely recognized, and Stubblefield as the Father of Broadcasting, a claim which has more merit. Loren J. Hortin, Journalism Professor at Murray State, organized his students to investigate Stubblefield's work, leading to the dedication of a monument on campus in 1930. Hortin later said "Radio is a device that transmits and receives voice over considerable distance without connecting wires. Stubblefield invented, manufactured, and demonstrated such a device and did so before anyone else on the planet." The radio station in Murray, WNBS, used Stubblefield's initials in its call letters.
