From PBS FEBRUARY ONE:
In one remarkable day, four college freshmen changed the course of American history. On February 1, 1960, Ezell Blair, Jr. (now Jibreel Khazan), David Richmond, Franklin McCain and Joseph McNeil—later dubbed the Greensboro Four—began a sit-in at a Woolworth’s lunch counter in a small city in North Carolina. The act of simply sitting down to order food in a restaurant that refused service to anyone but whites is now widely regarded as one of the pivotal moments in the American Civil Rights Movement.
The Greensboro Woolworth’s lunch counter was integrated in July 1960.
