Book: Alexander Graham Bell Bell's entire life was as exciting and dramatic as his great discovery, that being the secret of sending sound over wires. He did not rest on his laurels, but in spite of poverty and obstacles, went through life searching. He was one of the great pioneers in aviation. He was the inventor of the phonograph record, a new type of speed boat and a method of sending the voice over a ray of light. This is an informal and authoritative rendering of Bell's life.
