Hey Stan, yes Edison had an ongoing feud with GE over AC/DC, but his Co. was Edison Electric, later called Consolidated Edison. Edison invented direct current and Tesla (GE) invented alternating current. Direct current was used in the first electric chair, which gave GE all the propaganda they needed to discredit direct current. GE won popular approval and AC is still being used today.

There are actually three estates on that area of Mcgregor Blvd. that were lived in by Edison, Henry Ford, and Harvey Firestone. Ford had a house next door to Edison, and Firestone lived in a rented house on the other side of Ford. Ford worked for Edison as a young man and became a lifelong friend.

His last experiment (working with Ford and Firestone) was to extract natural rubber from the goldenrod plant, which in essence is just a weed. Ford and Firestone needed it for tires. Edison died before they could mass produce it. Soon after, Dupont invented synthetic rubber, so the project was scrapped.

My brother was given a couple of souvenirs for working at the Edison home. He has an original hand blown light bulb (no it doesn't work), and an "Edison Gold Moulded Record". It's a vinyl cylinder dated 1902. The song is called "I Wonder Who's Kissing Her Now" by unknown artist.

There is also one of maybe seven original stradivarius violins at the museum, given to Edison by Tsar Nicolas.
