"Dick" McMahon was born in Fredonia, Kansas, about 1880. Around 1896, he started as a groom and learned the art of driving trotters with the Steward Brothers of Kansas City, Missouri. His first claim to fame was a pacer, Major Muscovite, at the turn of the century. McMahon maintained a public stable until he went with Calumet Farm in Kentucky. With the Calumet horses he won many stakes, including the 1931 Hambletonian with Calumet Butler. McMahon retired from racing after the 1931 season to manage Calumet Farm. McMahon was rated one of the best race drivers of his time. A very handsome man, he was loved and respected by many. He died in Kentucky in 1945.
