Alexander Graham Bell

True or False? The telephone was Alexander Graham Bell's first invention. False! Alexander Graham Bell invented a talking machine when he was fifteen years old. Even before that he had invented wheat husker. As a young man, he taught deaf children how to talk at a school in Boston, Massachusetts. He invented a metal detector that was used in several wars to find bullets in wounded. Later in life, he experimented with small airplanes and special boats called hydrofoils. One hydrofoil set a speed record of seventy-one miles per hour in 1919, making it the fastest boat in the world.McPherson, Stephanie Sammartino is the author of 'Alexander Graham Bell ', published 2007 under ISBN 9780822576068 and ISBN 0822576066.
