Alexander Graham Bell, 1847-1922
Scottish-born Alexander Graham Bell studied speech from an early age. While trying to improve the telegraph, Bell discovered that the voice could be transformed into electric current and transmitted over a wire. He exhibited his telephone at the 1876 Centennial Exhibition in Philadelphia, where the startled emperor of Brazil exclaimed, "I hear, I hear!" Bell's invention revolutionized communication, leading to the establishment of the Bell Telephone Company. Upon learning of the inventor's death, his friend and competitor Thomas Edison observed: "[he] brought the human family in closer touch."
