First female Kentucky Derby jockey Diane Crump dead at 77

Diane Crump, the first woman to compete in the Kentucky Derby as a jockey, died this week at the age of 77. 

Crump was diagnosed in October with an aggressive form of brain cancer and died Thursday night in hospice care in Winchester, Virginia, her daughter, Della Payne, told The Associated Press.

In 1969, she became the first woman to ride professionally in a horse race and, a year later, she became the first female jockey in the Kentucky Derby. It would be 14 more years before another woman would ride in the event.
