Horatio A. Luro (February 27, 1901 - December 16, 1991) was a thoroughbred horse racing trainer in the United States. Luro was born in Argentina as one of nine children into the wealthy family of rancher and meat packer Adolfo Luro. The family had been involved for several generations with the lucrative business of polo horses, and Horatio Luro grew up as something of a playboy and maintained this lifestyle after moving to the United States. Well connected, he was friends with the social and business elite who could afford to be involved in the costly sport of thoroughbred racing. One of those elite was Canada's E. P. Taylor (1901–1989), chairman of a giant business conglomerate, the founder of the Jockey Club of Canada, and later the president of the National Thoroughbred Racing Associati
