R. G. LeTourneau
Robert Gilmour "R. G." LeTourneau (; November 30, 1888 – June 1, 1969), born in Richford, Vermont, was a prolific inventor of technologies related to earthmoving machinery, and founder of LeTourneau Technologies and LeTourneau University. His factories supplied machinery which represented nearly 75 percent of the earthmoving equipment used by the Allied forces during World War II, and more than half of the 1,500-mile (2,414 km) Alaska Highway in Canada, "Alcan", was built using LeTourneau equipment.
