9 Inventions Edison Did Not Make
By Jawad on Web 2.0
"Keep on the lookout for novel ideas that others have used successfully. Your idea has to be original only in its adaptation to the problem you’re working on." – Thomas Edison
Much of what the public knows about America’s most celebrated inventor is riddled with misconceptions. Among other things, the shrewed businessman Thomas Alva Edison, did not invent the light bulb. Following is a list of inventions that are often attributed to Edison, but were in fact not his making.
1. The Electric Bulb or Incandescent Lamp
Ask any child who invented the light bulb, and the answer is likely to be "Thomas Edison". Contrary to what schools have taught for years, the American icon, Thomas Edison, neither invented the light bulb, nor held the first patent to the modern design of the light bulb. In reality, light bulbs used as electric lights existed 50 years prior to Thomas Edison’s 1879 patent date. In fact, Edison lost all patent rights to the light bulb both in Britain and the United States.
2. The Electric Chair
The first practical electric chair was invented by Harold P. Brown. Brown was an employee of Thomas Edison, hired for the purpose of researching electrocution and for the development of the electric chair. Since Brown worked for Edison, and Edison promoted Brown’s work, the development of the electric chair is often erroneously credited to Edison himself. Furthermore, Brown’s design was based on George Westinghouse’s alternating current (AC), which was then just emerging as the rival to Edison’s less transport-efficient direct current (DC), which was further along in commercial development.
