So Now You Know

On February 1, 1960, four African-American students sat down at a segregated lunch counter in a Greensboro, North Carolina Woolworth's store. They were refused service, touching off six months of sit-ins and economic boycotts that became a landmark event in the U.S. civil-rights movement. In 1993, an eight-foot section of the lunch counter was moved to the Smithsonian Institution.
