The National Inventors Hall of Fame (NIHF) is an American not-for-profit organization which recognizes individual engineers and inventors who hold a U.S. patent of highly significant technology. Founded in 1973, its primary mission is to "honor the people responsible for the great technological advances that make human, social and economic progress possible." Besides the Hall of Fame, it also operates a museum in Alexandria, Virginia, and a middle school in Akron, Ohio, and sponsors educational programs, a collegiate competition, and special projects all over the United States to encourage creativity among students.
