The Center, founded in 1948 by Mamie Clark, who was soon joined by Kenneth B. Clark, has for generations pioneered in the training and education of children from the City of New York. The Center also served as the locus of the initial experiments on the racial biases of education that led to the 1954 Supreme Court decision outlawing segregated education. These thirty-seven interviews detail the history of the intersection of education and varying theories and practices of psychology and social psychology that defined the Center. Staff, board members, and community activists were interviewed for a full range history of the Center. The interviews provided a part of the research base for David Rosner and Gerald E. Markowitz, Children, Race, and Power: Kenneth and Mamie Clark's Northside Center.
