Quack was an American Thoroughbred racehorse who holds the world record for a three-year-old with the fastest mile and a quarter ever run on dirt. He was sired by T.V. Lark, the 1961 American Champion Male Turf Horse, and out of the mare Quillon, a daughter of the outstanding Champion broodmare sire Princequillo. Quack was a very large horse whose style was to lag behind early and finish with a devastating closing kick. He was a bay with a spot of white on his forehead. Though Quack had success early in his career with Hall of Fame jockey Bill Shoemaker, he found even more success with Hall of Fame jockey Don Pierce, whose first ride on him was the 1972 Hollywood Gold Cup.
