They Changed the World: Bell, Edison and Tesla

Despite having three completely different approaches, Alexander Graham Bell, Thomas Edison and Nicola Tesla each made significant contributions to the field of science and laid the foundation for modern technology.  As their paths crossed, a rivalry grew, with Tesla pushed into the shadows of history until a resurgence in the 1990s.  They Changed the World tells the story of the men who revolutionized the fields of light, sound and vision, while competing with each other for recognition.

"By focusing on the social and economic differences among Nikola Tesla, Alexander Graham Bell, and Thomas Edison, as well as their shared hunger for making monumental discoveries in electronics that could—and did—alter the modern world, the writer and the artist show plainly that an inventor’s creativity is but one ingredient in his or her achievements and that commercial success takes a toll on the inventor’s life outside the lab. . . Helfand’s solid research is a great jumping-off point for student researchers." — Francisca Goldsmith, Booklist
