Fessenden: Builder of Tomorrows - Helen May Trott. Fessenden - Hardcover

Based on her husband's unfinished autobiography and her own letters, Helen Fessenden wrote what remains the definitive biography of one of America's most eminent radio pioneers, responsible for the two-way radio, the wireless telephone, the sonic depth finder and the submarine telephone. Using heavy documentation, she traces Fessenden's life as a series of confrontations and crises interspersed with several important achievements: the alternator principle, the first broadcast station (1906), and heterodyne theory. When it was published in 1940, The New York Times called Fessenden: Builder of Tomorrows, "a valuable and entertaining biography". Books stated that this biography "should be read by all who realize that creative ideas are the only hope of the nation and the race".Fessenden, Helen is the author of 'Fessenden: Builder of Tomorrows - Helen May Trott.
