Full Answer

Peter Cooper Hewitt built upon the work of Julius Plucker and Heinrich Geissler, who applied electricity to tiny gas particles in a tube to create light. Hewitt created a bluish-green light with a mercury-filled tube. He teamed up with George Westinghouse to become the first team to manufacture it commercially. Thomas Edison applied for a patent in 1896, but his fluorescent light used X-rays to excite the atoms and never sold.
