McCain's son Frank McCain said today he died in North Carolina of respiratory complications late yesterday.
Franklin McCain was one of four students from North Carolina A&T State University who sat down at the segregated lunch counter on Feb. 1, 1960.
McCain, Joseph McNeil, Ezell Blair Jr. And David Richmond returned the following days with other protesters growing to at least 1,000 by the fifth day. Within weeks, sit-ins launched in more than 50 cities in nine states.
McCain became a research chemist. Richmond died in 1990.
