Holless Wilbur Allen ran a small archery shop in Missouri. In 1966 he grabbed a hacksaw, sawed the ends off a recurve bow and bolted a pulley onto each limb. He patented it in 1969, the first compound bow. The Smithsonian keeps his patent model. More than 1.2 million students a year now learn archery on a compound bow like his, in schools across all 50 states. Bowhunters still draw one every fall.
