Lodge, president of the Royal Society, called him "the greatest man in the world".
American President Hoover said: "Edison is the most famous person in America, a national treasure of America and a benefactor of mankind."
Miller said in Edison's Biography: "Without God's revelation, without the helmsman and guiding power, Edison would never have the precise mind of science and mathematics to understand the mysteries of the universe. Celestial planets keep rotating in a certain orbit for thousands of years; The wonder of creation, the diversity of life, and the magic of animals, plants and minerals all make him believe that there must be a god in the universe. "
Edison's cultural level is extremely low, but his contribution to mankind is so great. Edison not only has a curious heart and an instinct to try by himself, but also has unlimited energy and courage to work beyond ordinary people.
