Johann Philipp Reis - In 1860 Reis was the first who produced a functioning electromagnetic device that could transmit musical notes, indistinct speech, and occasionally distinct speech by means of electric signals. Antonio Meucci - An early voice communicating device was invented around 1854 by Antonio Meucci, (who called it a telettrofono.) In the 1880s Meucci was credited with the early invention of inductive loading of telephone wires to increase long-distance signals.

On kindlaks tehtud, et enne Belli leitas telefoni Antonio Meucci. Veel võistle Bell Elisha Gray-ga, kes ennem telefoni valmis saab. Bell jõudis paar tundi ennem seda teistele näidata ja võitis. Siis hakkasid nad kohtus käima ja lõppude lõpuks võitis ikka Bell. Alexander Graham Bellist Alexander Graham Bell sündis Edinburghes 3. märtsil 1847.
