The young man

Alexander Graham Bell was born on March 3, 1847, in Edinburgh, Scotland. His father, Alexander Melville Bell, was an expert on the mechanics of the voice and on elocution (the art of public speaking). His grandfather, Alexander Bell, was an elocution professor. Bell's mother, Eliza, was hard of hearing but became an accomplished pianist (as well as a painter), and Bell took an interest in music. Eliza taught Alexander, who was the middle of three brothers, until he was ten years old. When he was a youth he took a challenge from a mill operator and created a machine that removed the husks from grain. He would later call it his first invention.
