 nathan b. stubblefield (november 22, 1860 - march 28, 1928) was an american inventor and kentucky melon farmer. it has been claimed that stubblefield demonstrated radio in 1892, but his devices seem to have worked by audio frequency induction or, later, 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, which would, however conflict with the four documented patents for the photophone, invented jointly by alexander graham bell and charles sumner tainter in 1880. the photophone allowed for the transmission of sound on a beam of light, and on june 3, 1880 bell and tainter transmitted the world's first wireless telephone message on their newly invented form of telecommunication.carson, mary kay (2007) alexander graham bell: giving voice to the world, sterling biographies, new york, ny 10016: sterling publishing co., inc.. pp. 76-78. isbn 978-1-4027-3230-0. oclc 182527281phillipson, donald j.c., and neilson, laura bell, alexander graham, the canadian encyclopedia online. retrieved 2009-08-06 ==biography== image:file:274788.jpg|à¸à¸²à¸à¸²à¸ à¸à¸µ. à¸ªà¸à¸±à¸à¹à¸à¸´à¸¥à¸à¸´à¸¥à¸à¹ (nathan b. stubblefield) ===early years and family life=== stubblefield was the second of seven sons of a lawyer, william "capt. billy" jefferson stubblefield (1830â1874), and his mother victoria bowman (1837-1869) died of scarlet fever. stubblefield lived in [
