Thomas Edison inventor

Many inventions come from a pure chance.  One such example is from the American inventor Thomas Edison, most known as the founder of the light bulb and the phonograph . In 1875 Thomas Edison happened to discover the photocopying, when he used paraffin to try to improve the telegraph wire.

However,  Chester Carlson is officially the inventor of the photocopying and he applied for the patent for the process in 1938.
