By the time Thomas Edison was 23, his passion to experiment and develop new inventions had earned him a number of patents. Although not all of Edison's creations were popular or useful enough to be mass-produced, many paved the way for future technology. The images in this gallery show advertisements and uses of a few of the mechanisms Edison created.
