Thomas Edison filed a patent (U.S. Patent 865,367) on May 9, 1896 for a fluorescent lamp that was never sold. However, he did not use mercury vapor to excite the phosphor. His lamp used x-rays.
================
In 1857, the French physicist Alexandre E. Becquerel who had investigated the phenomena of fluorescence and phosphorescence, theorized about the building of fluorescent tubes similar to those made today. Alexandre Becquerel experimented with coating electric discharge tubes with luminescent materials, a process that was further developed in later fluorescent lamps.
===========================
American, Peter Cooper Hewitt (1861-1921) patented (U.S. patent 889,692) the first mercury vapor lamp in 1901. The low pressure mercury arc lamp of Peter Cooper Hewitt is the very first prototype of today's modern fluorescent lights. A fluorescent light is a type of electric lamp that excites mercury vapor to create luminescence.
