The Ruskin Colleges were a group of American colleges founded in the early 20th century by the socialist philanthropist Walter Vrooman, the college administrator George McAnelly Miller, and others, in the same spirit as the British Ruskin College, which Vrooman had cofounded. A core idea was for students to gain vocational training and earn their way through college by working in a cooperative business associated with the college. Ruskin Colleges were founded in Missouri, Illinois, and Florida.
