Science educator Dennis Schatz has written for children a biography of Thomas Edison. In this 40-page book, Schatz describes Edison's life and his world-changing inventions: the phonograph, electric lighting, movie projectors, and more. The book includes a hand-crank-powered kinetoscope, filmstrip images to view, and blank strips to make simple moving pictures. Schatz is senior vice president for strategic programs at Pacific Science Center, in Seattle. A research solar astronomer prior to his career in science education, he worked at the Lawrence Hall of Science at the University of California, Berkeley.
