Thomas Edison
Back in 1879, when people first got wind of Thomas Edison’s latest invention, the general reaction was lukewarm at best. In fact, it was condemned by one Scientist from the Stevens Institute of Technology as ‘a conspicuous failure’ and ridiculed by others as the stuff of fairy tales, “unworthy of the attention of practical or scientific men.” The invention in question? The lightbulb. Edison went on to file over a thousand patents for his various inventions and is known as one of the greatest inventors who ever lived.
