A legendary piece of construction history arrived at the National Inventors Hall of Fame Museum on April 19.
Joe Keller, the son of 2023 National Inventors Hall of Fame Inductee Louis Keller and nephew of Inductee Cyril Keller, was on a cross-country trip with the Keller brothers' invention — a 1958 prototype skid-steer loader.
Keller brought the loader to Alexandria, Va., where the prototype will be part of an exhibit at the National Inventors Hall of Fame Museum honoring the 2023 Class of Inductees, who will be recognized in October during NIHF's 50th anniversary Induction Ceremony.
