Diane Crump, a pioneering female jockey who broke gender barriers in horse racing, passed away at 77 after being diagnosed with aggressive brain cancer. In 1969, she became the first woman to ride professionally in a horse race and, a year later, the first female jockey to compete in the Kentucky Derby. Despite facing significant opposition, including boycotts from male jockeys, Crump persevered and won 228 races before retiring in 1998. Her trailblazing efforts opened doors for future generations of female jockeys and earned her lasting respect in the racing community.

Beyond her racing career, Crump was known for her determination and compassion, running a horse business after retirement and visiting patients with her therapy dogs. Her legacy is celebrated for courage and progress, inspiring many within and beyond the sport. Tributes from Churchill Downs and the Kentucky Derby Museum highlight her iconic status and the profound impact she had on horse racing and society.
