Thomas Edison did not invent the lightbulb, shocking I know! In 1879 Edison produced something that everyone around the world needed, but it wasn't his idea. Although he perfected the lightbulb he did not invent it. The idea originated in Canada by 2 men. Henry Woodward and Matthew Evans. They successfully produced an electric filament lamp a full 5 years before Edison. The 2 Canadians sold their patent to Edison in 1879. Some believe Edison stole the patent and released it as his own. The only reason Edison gains credit for the revolutionizing invention instead of Henry Woodward and Matthew Evans is simply because Edison got the filament to burn longer and more efficient than them.
