Tech History Made on February 11, 1847

On this day 161 years ago a great inventor was born, Thomas Edison. Edison holds that record for most patents, alone and jointly that is 1,093 patents. His first patent in 1869 was for a electrographic vote recorder. It allowed legislators to place a vote for or against with the flip of a switch. It did not catch on because lobbyists lost the chance to convince a vote change during the time it normally took to count the physical ballots. Here a just a few thing he patented:
Incandescent Lamp
Printing Telegraph
Electro Magnets
Electric lights
Phonograph(pictured above)
