Answer: Thomas Edison
Explanation: In his 84 years, Thomas Edison acquired a record number of 1,093 patents (singly or jointly) and was the driving force behind such innovations as the phonograph, the incandescent light bulb and one of the earliest motion picture cameras. He also created the world's first industrial research laboratory. Born in 1847, Edison would witness tremendous change during his lifetime. ... Edison invented or refined devices that made a profound impact on how people lived. The most famous of his inventions was the incandescent light bulb (1878), which would revolutionize indoor lighting and forever separate light from fire. Edison realized that the problem with Swan's design was the filament. A thin filament with high electrical resistance would make a lamp practical because it would require only a little current to make it glow. He demonstrated his light bulb in December 1879. Thomas Edison created many inventions, but his favorite was the phonograph. While working on improvements to the telegraph and the telephone, Edison figured out a way to record sound on tinfoil-coated cylinders. In 1877, he created a machine with two needles: one for recording and one for playback.
