Joseph McGraw began his career in harness racing as a trainer and farm manager in Meadow Lands, Pennsylvania. He went on to become an official at tracks, acting as a judge, timer and handicapper. After fifty years service on the Grand Circuit, McGraw became known as the "Dean" of presiding judges and then, finally, as the "Judge Landis" of harness racing. It was McGraw who invented one of the early starting devices for the harness track, known as the snap barrier. McGraw was also responsible for adding claiming races to cards to help support main events. He died in 1964.
