Tobey showed at New York's Whitney Museum in 1951. He also spent three months as guest critic of graduate students' work at Yale University on the invitation of Josef Albers, and had his first retrospective show at the California Palace of the Legion of Honor in San Francisco. In 1952, the film "Tobey, Mark: Artist" debuted in the Venice and Edinburgh film festivals. Acknowledging "academic responsibility," Hallsten enrolled in graduate school at the University of Washington's department of Scandinavian languages and literature in the early 1950s and, after receiving his master's degree, Tobey began referring to him by the honorific, Professor.
