Regarded as the classic standard biography on Thomas Edison. It is the only biography written in the last 40 years to be recommended by the official voice of the caretakers of the Edison Laboratory National Monument in New Jersey which houses all of Edison's original records, sketches, notes, correspondence and memoranda. Depicts Edison as a pivotal figure in America's economic and industrial revolution success and at the same time as a human being, including his exploitative and, at times, crude qualities.
