Thomas Edison held 2,332 patents, the 1st one was never used
Born on February 11, 1847, American inventor Thomas Edison received the first of his then-record 2,332 patents (1,093 US patents) for an 'Electrographic Vote-Recorder', at the age of 21. When presented to the Congress committee, its chairman said, "If there is any invention on earth that we don't want down here, that is it." The vote recorder was never used.
