With 1,093 patents to his name, Thomas Edison has more than any other person in history—that’s an astonishing 13 patents for every year of his life! Though he claimed, “I never did a day’s work in all my life,” there’s no doubt that Edison was very busy, creating things we take for granted today: the electric lightbulb, recorded music, the stock ticker, and even motion-picture machines! Filled with historical photographs, diagrams, and illustrations, World of Inventors: Thomas Edison offers a captivating look at the man and his ingenious machines. Insightful sidebars introduce budding inventors to concepts like the scientific method, where to find inspiration, and the traits you need to be an inventor. Kids can then bring to life an invention of their own: a build-it-yourself model of an animation machine inspired by Edison.
