Kathrine Switzer was the first woman to run the Boston Marathon as a numbered entry.
She registered for the race under the gender-neutral “K. V. Switzer”. Race official Jock Semple attempted to physically 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, and other runners provided a shield for her. The photographs taken of the incident made world headlines.
