Mr. Prospector was a Thoroughbred racehorse who became an outstanding breeding stallion and notable sire of sires. A sprinter whose career was cut short by repeated injuries, he won seven of his 14 starts, including the Gravesend Handicap at Aqueduct Racetrack and the Whirlaway Handicap at Garden State Park.

Raise a Native was an undefeated Thoroughbred racehorse that was named 1963 champion two-year-old colt in the Turf and Sport Digest poll and was the highest rated juvenile in the Experimental Free Handicap. He sired 74 stakes winners, including Majestic Prince and Alydar. In its 1988 obituary for the horse, The New York Times called him "the most influential sire of American Thoroughbred stallions over the last 20 years".
