Hello, Rainy." - In 1892, ignorant of the wireless inventions of the past 60 years, Nathan creates an electromagnetic induction wireless telephone and demonstrates it to his friend Rainey Wells. A few years later, Nathan develops a superior wireless telephone that uses natural conduction through the earth and water.

Stubblefield was experimenting with ground radio since 1882, but did not patent his developments until much later. Credible witnesses saw his ground radio experiments in action during this time frame, establishing the historical priority of Stubblefield. While Marconi could barely send telegraphic "dots and dash" signals with great difficulty through a static-filled medium, Nathan Stubblefield had already transmitted the human voice with loud, velvet clarity. Others would adopt and implement the Collins system (Fessenden, DeForest, Bethenod, Braun), but none could duplicate the Stubblefield System.

Stubblefield researched "Magnetic Waves" and developed several systems which did not use ground terminals for exchanging signals. Long distance wireless telephone communications were his aim. Many imagined this to be radio as we know it, but several features of Stubblefield aerial are distinctive and different.

Mr. Stubblefield reasoned that, since electrical waves traverse the whole earth, it might be possible to send signals to distant places. These ground-permeating natural electrical waves might serve as carriers for the human voice. The ground would act as both power generator and signal conductor.

1882 - Transmitted audio frequency electromagnetic signals
1885 - Transmitted the Human Voice, using his induction coil transmitter
1892 - First to Broadcast Human Voice, using his wireless telephone attached to a landaerial - First Wireless Telephone Broadcasting Demonstrations [Voice]
1898 - May 8 -- Patent Wireless Telephone Transmission Coil
1902 - First Ship-to-Shore wireless telephone Broadcast, using wires dropped in the water from the steamer Bartholdi-
1908 - Patented the All-in-One Wireless Telephone for Auto/Ship/Train : patent US887357.

P.S.:"Tesla was among the curious onlookers in attendance at Stubblefield's 1902 wireless demonstration in Philadelphia."
