Born Darnell Wayne Lukas on Sept. 2, 1935, in Wisconsin as the second of three children, he rose to prominence in the sport with quarter horses in races that are effectively sprints. He moved into thoroughbreds in the late 1970s and won his first Preakness with Codex in 1980.

D. Wayne Lukas, the Hall of Famer who won 15 Triple Crown races, including seven Preakness victories, has died.

In 1968, Lukas moved to California and began training quarter horses. He found success, overseeing 24 world champions in 10 years. He then switched to thoroughbreds, saddling his first winner at Santa Anita in 1977. He became the first trainer to earn over $100 million in purse money, and 14 times he led the nation in money won.
