A Brief History of the Sit-In Movement

The Four Original Protesters
In 1980, the original four North Carolina A&T students returned to Greensboro for a ceremony, above, marking the 20th anniversary of their act of civil disobedience. Joseph McNeill, far left, went on to serve in the U.S. Air Force, attaining the rank of captain; David Richmond, second from left, became a counselor-coordinator for the Comprehensive Employment Training Act program in Greensboro before passing away in 1990; Franklin McCain, second from right, worked as a chemist for the Celanese Corporation; and Ezell Blair Jr., far right, who now goes by the name Jibreel Khazan, attended law school at Howard University and currently works with developmentally disabled people in New Bedford, Mass.
