"One would think that I had never done anything worthwhile but the telephone," complained Alexander Graham Bell. No wonder he was annoyed; Bell invented the phone when he was just 29 and went on to lead a long and inventive life.This biography in the Snapshots: Images of People and Places in History series chronicles the life and many remarkable achievements of Alexander Graham Bell, including his work with the hearing impaired and experiments with flight, iceberg locators and, of course, the telephone.
