William Condren, 74; co-owned 1991 and 1994 Kentucky Derby winners

William Condren, 74, co-owner of Kentucky Derby-winning Thoroughbred horses Strike The Gold and Go For Gin, died Monday at Massachusetts General Hospital in Boston, the hospital said. The cause of death was not announced.

Condren, Joseph Cornacchia and B. Giles Brophy won the 1991 Derby at Churchill Downs with Strike The Gold, but the partnership was strained. Condren and Cornacchia later bought Brophy’s share in Strike The Gold, and in 1994 the remaining two co-owners won the Derby with Go For Gin. Condren and Cornacchia also owned 1996 Preakness winner Louis Quatorze.

Most of Condren’s racing success came with Hall of Famer Nick Zito, who trained Strike The Gold, Go For Gin and Louis Quatorze.

Condren was a co-founder and director of the National Thoroughbred Assn. and a trustee for the Thoroughbred Owners and Breeders Assn. He also served on the board of directors of the Grayson-Jockey Club Research Foundation.

A private investor with interests in real estate, oil and gas drilling and aircraft leasing, Condren was born in New York City and attended Fordham University and Harvard Law School.
