Johann Philipp Reis

Johann Philipp Reis (; 7 January 1834 – 14 January 1874) was a self-taught German scientist and inventor. In 1861, he constructed the first ''make-and-break'' telephone, today called the Reis telephone. It was the first device to transmit a voice via electronic signals, and is regarded by some as the first telephone. Reis also coined the term telephone. Provided by Wikipedia
