Otto Klineberg

Otto Klineberg was a Canadian born psychologist. He held professorships in social psychology at Columbia University and the University of Paris. His pioneering work in the 1930s on the intelligence of white and black students in the United States and his evidence as an expert witness in Delaware were instrumental in winning the Supreme Court school segregation case Brown v. Board of Education in 1954. Through his work in UNESCO and elsewhere, he helped to promote psychology internationally.
