Nathan Beverly Stubblefield (* 22. November 1860 in Murray; † 28. März 1928 ebenda) war ein amerikanischer Erfinder und Melonenfarmer. Er erhielt unter anderem 1908 das US-Patent für eine induktive drahtlose Sprachübertragung und gründete damit verbunden den wahrscheinlich weltweit ersten Sprechfunkanbieter namens Wireless Telephone Company of America.

Nathan Beverly Stubblefield (22 de noviembre de 1860 - 28 de marzo de 1928), fue un inventor estadounidense conocido por su trabajo en telefonía inalámbrica. Aunque su dispositivo usaba inducción electromagnética y no ondas de radio propiamente dichas, posiblemente fue el primero en enlazar múltiples receptores simultáneamente.

Nathan Beverly Stubblefield (22 novembre 1860 – 28 marzo 1928) è stato un inventore statunitense e coltivatore di meloni in Kentucky. È stato dichiarato che avesse inventato la radio prima di Nikola Tesla, Aleksandr Stepanovič Popov o Guglielmo Marconi, ma i suoi dispositivi sembrano lavorare sull'induzione di frequenze audio (creando disturbi vicino al campo) piuttosto che sulla radiazione di radio frequenza per le telecomunicazioni per trasmissioni radio. Sebbene al tempo vi fossero esperimenti di altri contemporanei come , egli è stato proposto come uno dei pretendenti all'invenzione della telefonia senzafili, o per le trasmissioni senza fili della voce umana.

Nathan Beverly Stubblefield (November 22, 1860 – March 28, 1928) was an American inventor best known for his wireless telephone work. Self-described as a "practical farmer, fruit grower and electrician", he received widespread attention in early 1902 when he gave a series of public demonstrations of a battery-operated wireless telephone, which could be transported to different locations and used on mobile platforms such as boats. While this initial design employed conduction, in 1908 he received a U.S. patent for a wireless telephone system that used magnetic induction. However, he was ultimately unsuccessful in commercializing his inventions. He later went into seclusion, and died alone in 1928.

However, he was ultimately unsuccessful in commercializing his inventions. He later went into seclusion, and died alone in 1928. Disagreement exists whether Stubblefield's communications technology can be classified as radio, and if his 1902 demonstrations could be considered the first "radio broadcasts". Most reviews of his efforts have concluded that they were not radio transmissions, because his devices, although they used a form of "wireless", employed conduction and inductive fields, while the standard definition of radio is the transmission of electromagnetic radiation. However, Stubblefield may have been the first to simultaneously transmit audio wirelessly to multiple receivers, albeit over relatively short distances, while predicting the eventual development of broadcasting on a national scale.
