註釋

". . . rarely have inventor and invention been better served than in this book."- New York Times Book ReviewHere, Edwin Grosvenor, American Heritage's publisher and Bell's great-grandson, tells the dramatic story of the race to invent the telephone and how Bell's patent for it would become the most valuable ever issued. He also writes of Bell's other extraordinary inventions: the first transmission of sound over light waves, metal detector, first practical phonograph, and early airplanes, including the first to fly in Canada. And he examines Bell's humanitarian efforts, including support for women's suffrage, civil rights, and speeches about what he warned would be a "greenhouse effect" of pollution causing global warming.
