Thomas Alva Edison was born on February 11, 1847, in the small town of Milan, Ohio.
Throughout his lifetime, he earned $4, and became the driving force behind some of the $4 of the 20th Century.
Not only did he conceive of ideas as original as the phonograph and alkaline battery, but he also worked to expand on existing ideas - such as the $4 - and brought them to fruition in creative ways.
His mind was so rampant with invention that he became known as the "$4," and his list of works far exceeds what most of us have come to know him by.
Here some of the most remarkable inventions you probably never knew Edison and his research assistants created.
