MacKenzie "Mack" Todd Miller (October 16, 1921 – December 10, 2010) was an American Thoroughbred racehorse trainer and owner/breeder. During his forty-six-year career, he conditioned seventy-two stakes winners, including four Eclipse Award champions.
Education and military service Mack Miller grew up near the Keeneland Race Course, and attended its first race in 1936. He studied at the Bolles School in Jacksonville, Florida then at the University of Kentucky but interrupted his education to serve with the United States Army Air Forces during World War II. After the war's end, in 1947 he went to work as a stable hand for Calumet Farm. He became involved with conditioning horses, and took out his training license in 1949.
