There were hundreds of great inventions in the 1800s such as the telephone, steel plow, reaper, and the revolver. Thomas Edison is one of the greatest inventors of all time. He is most famous for inventing the light bulb, but there are some other inventions you might not know about. His first great invention was the tin foil phonograph that would prick holes in tin foil to spell words. The first transmission was "Mary had a little lamb." One of the uses of the phonogragh was to read books to the blind.
He also established a company to sell the machine. He invented the zooproxiscope which is basically the first video camera. He first called it a kinectiscope. Estamon Kodak started supplying film to Edison. He also invented a vitascope to project the films.
Not everything Edison did suceeded. He had 1,093 patents for inventions. One ivention that never worked was using cement to build things which we do now of course. The biggest failure was he couldn't find a way to mine iron ore. He tried unsuccessfully for 10 years, but he had to sell his stock in general electric to pay off his debt.
Thomas Edison is still one of the greatest inventors ever, but even the best fail sometimes.
