Kathrine Switzer was the first woman to run the Boston Marathon in 1967 as a numbered entry. She registered under the gender-neutral "K. V. Switzer."
Race official Jock Semple attempted to remove her from the race, and according to Switzer said, "Get the hell out of my race and give me those numbers." However, Switzer's boyfriend Tom Miller, who was running with her, shoved Semple aside and sent him flying. The photographs taken of the incident made world headlines.
