Saturday marks the 60th anniversary of the Greensboro Four sit-in protest at the lunch counter at Woolworth’s in downtown Greensboro, North Carolina. On February 1, 1960, four freshmen students at North Carolina’s A&T State University — Ezell Blair Jr., Franklin McCain, Joseph McNeil and David Richmond — refused to leave the whites-only lunch counter after being denied service. Their action inspired a nationwide wave of sit-ins aimed at desegregating businesses and public spaces. Within weeks of their action, sit-in protests spread to over 250 cities and towns across the country, sparking a nationwide movement that saw more than 400 protests by the end of the year.
