Thomas Alva Edison (February 11, 1847 â€“ October 18, 1931) 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.

"The existence of an intelligent Creator, a personal God, can to my mind, almost be proved from chemistry," writes Edison; and George Parsons Lathrop, in commenting upon Edison's belief, says:- "Surely it is a circumstance calculated to excite reflection, and to cause a good deal of satisfaction, that this keen and penetrating mind, so vigorously representing the practical side of American intelligence - the mind of a remarkable exponent of applied science, and of a brilliant and prolific inventor who has spent his life in dealing with the material part of the world - should so confidently arrive at belief in God through a study of those media that often obscure the perception of spiritual things." Edison, it seems, like Keely, has never been discouraged by the obstacles which he meets with, in his researches, nor even inclined to be hopeless of ultimate success.
"Unlike Keely, Edison through all his years of experimental research has never once made a discovery. All the work of this great and successful inventor has been deductive, and the results achieved by him have been simply those of pure invention. Like Keely he constructs a theory, and works on its lines until he finds it untenable; then, he at once discards it and forms another theory. In connection with the electric light, he evolved or constructed three thousand successive theories; each one reasonable and apparently likely to be true; yet, only in two cases was he able to prove by experiment that his theories were correct. Of such a nature is the "dead-work" which all researches on scientific principles must toil through to attain success." Bloomfield-Moore, More Science
