What was Thomas Edison’s first patent?
Electric voting machine
Throughout the 20th century, Edison was the world’s most prolific inventor. At the beginning of the century, he held 736 U.S. patents. His final count was 1,093 U.S. patents, including 1084 utility patents (patents for inventions) and 9 artistic design patents.
On June 1, 1869 Thomas Edison was granted his first patent for an electric voting machine. Unfortunately, Congress wanted no part of the device, so young Edison’s vote-recorder was sent to the political graveyard.
His next invention fared much better: an improved stock market tickertape machine, which earned him an instant $40,000 (about $700,000 today). He would continue to develop many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb.
