Here is the dramatic story of the race to invent the telephone and how Bell's patent would become the most valuable ever issued. The authors also write 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 they examine 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.
Edwin Grosvenor is American Heritage's editor-in-chief and Bell's great-grandson. Morgan Wesson is a filmmaker and journalist in upstate New York.
