                   Archimedes may have used his principle of buoyancy to determine whether 

                      the golden crown was less dense than solid gold.

Thomas Alva Edison                               
February 11, 1847 -  October 18, 1931 (aged 84) U.S.A
He was an American inventor, scientist, and businessman who developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park" (now Edison, New Jersey) by a newspaper reporter, he was one of the first inventors to apply the principles of mass production and large teamwork to the process of invention, and therefore is often credited with the creation of the first industrial research laboratory.
