5. Thomas Edison And The Phonograph
Thomas Edison is perhaps on of the most famous inventors of all time because of his many useful inventions like the light bulb, the motion picture camera, and pictured here the phonograph. Edison invented the phonograph in 1877 when he was developing a machine that could record and play back sound. It’s no secret that Edison invented the phonograph, but have you ever actually seen the photograph of him unveiling it? I didn’t think so–pretty cool, isn’t it?
