How many inventions did Thomas Edison steal?

I know he took the credit for the light bulb when it wasn't his invention. Are there any others?
I'm just curious. It isn't for a test.

Update: Vegas Jimmy - It is a well known fact that the lightbulb is a British Invention, whether you like it or not.
I have never stolen anything in my life. I would never take the credit for someone elses work either.
