Thomas Edison Facts

Thomas Edison taught his second wife Morse code so they could communicate in secret by tapping into each other's hands when her family was around. He even proposed to her this way — tapping "Will you marry me?" into her palm during a carriage ride. She tapped back "Yes."

Gustave Eiffel built a secret apartment at the top of his tower - 906 feet above Paris - with a piano, sitting room, and three small desks for science. Paris's wealthy offered him fortunes to rent it for a single night. He refused every offer. On September 10, 1889, Thomas Edison climbed up and gifted him a phonograph. The apartment still exists, with wax figures of Eiffel, Edison, and his daughter Claire inside.
