Harlem Youth Opportunities Unlimited, more commonly called HARYOU, was an American social activism organization founded by psychologists Kenneth Clark and Mamie Phipps Clark in 1962. Its director was Cyril deGrasse Tyson, father of astrophysicist Neil deGrasse Tyson, and founding member of the 100 Black Men of America.[1] The group worked to increase opportunities in education and employment for young blacks in Harlem. It also was designed to teach residents of Harlem how to work with governmental agencies to meet their demands.[2]
