Who is credited with inventing the fluorescent light bulb? Some resources told me it was Nikola Tesla, yet others told me it was a collaboration of Peter Cooper Hewitt, Edmund Germer, George Inman, and Richard Thayer. Can someone please clarify this for me? Thank you.

Answer 1

It was not Tesla. The other people you mentioned played a role at various times. A good history of the developnment can be found at:
