<DIV> <p>This addition to the Badger Biographies series tells the story of four young inventors who shared a dream: to create the best motorized bicycle in America. Their turn of the century aspirations took them from a backyard machine shop to a highly successful business empire - and all in the span of just a few years. With grit, determination, and not a little elbow grease, Bill Harley and the Davidson brothers - Arthur, William, and Walter - used their engineering and machine-shop expertise to continually perfect their designs and present the best possible products to the American public. Along the way they made their mark on the racing circuit and introduced safety measures that continue to this day. After their deaths, their sons and daughters continued this legacy, buying back the company after it changed hands and re-establishing Harley-Davidson as the king of the motorcycle world. From the old Knucklehead, Panhead and Shovelhead motors to the Evolution, Revolution and Twin Cam engines that followed, the story of Harley and the Davidsons remains one of the great success stories of the 20th century.</p> </div>
