The Rev. C.T. Vivian, a civil rights veteran who worked alongside the Rev. Martin Luther King Jr. and served as head of the organization co-founded by the civil rights icon, has died. Vivian died at home in Atlanta of natural causes Friday morning, his friend and business partner Don Rivers confirmed to The Associated Press. Vivian was 95. His civil rights work stretched back more than six decades, to his first sit-in demonstrations in the 1940s in Peoria, Ill. He met King soon after the budding civil rights leader’s victory in the 1955 Montgomery Bus Boycott. Vivian became an active member of what would become the Southern Christian Leadership Conference. “He has always been one of the people who had the most insight, wisdom, integrity and dedication,” said Andrew Young, who also worked alongside King.
