Robert Cooley Angell (born April 29, 1899, Detroit, Michigan, U.S.—died May 12, 1984) was an American sociologist known for his studies of individuals interacting in social groups such as government units, the church, the family, business enterprises, clubs, cooperatives, and other associations.
He received his education at the University of Michigan, obtaining his Ph.D. in 1924.
