Shuffling about his laboratory at Menlo Park, New Jersey, a shock of hair over one side of his forehead, sharp blue eyes sparkling, stains and chemical burns on his wrinkled clothing, Thomas Edison never looked like a man whose inventions had revolutionized the world in less than a lifetime. Certainly, he never acted like it. Once, when a visiting dignitary asked him whether he had received many medals and awards, he said, “Oh, yes, Mom’s got a quart of them up at the house.” “Mom” was his wife. Yet every day he demonstrated what a giant among men he was. Great were his contributions to mankind. He patented a record 1,093 inventions in his lifetime.
