For the first time in the 91-year history of the Indianapolis 500, three women will be in the same field: Milka Duno (far left), Sarah Fisher (second from left) and Danica Patrick (far right). Duno, a rookie driver from Venezuela, joins Fisher and Patrick, both veterans at Indy, on the 33-car grid. Here, we offer a photo essay of their careers, on and off the track, along with a few shots of the original women of Indy, Janet Guthrie and Lyn St. James. (The trio joined St. James, center, and tennis great Billie Jean King for a photo before the start of qualifications on May 12.)
