In 1894, he commissioned the first pushball: a leather-covered wooden frame, six feet three inches in diameter, which weighed around 70 pounds (32 kilograms). It cost him $175 ($6,775 in today’s money). His son Edwin helped devise the rules and the next year introduced it to Harvard, where he was at college. Twenty thousand people unwittingly attended an exhibition match on November 3, 1895, played during the half time of a football game between Harvard and the University of Pennsylvania; Edwin, of course, captained the Harvard team.
