List of National Inventors Hall of Fame inductees

The National Inventors Hall of Fame is an American not-for-profit organization, founded in 1973, which recognizes individual engineers and inventors who hold a U.S. patent of significant technology.
The inventor list constitutes historic persons from the past three centuries in addition to living inductees. Nominees must hold a U.S. patent of significant contribution to public welfare, and which advances science and the useful arts. John Fitch was the earliest born inventor inducted into the NIHF.
