The artists did the same - they paid dues, shared clerical and custodial duties, and mounted both combined and solo shows of their work. Because the artists were in the nascent stages of their careers, a definitive roster of the founding members of the Hansa Gallery is hard to pin down. According to an interview with Richard Bellamy, who joined the Hansa as Program Director in 1955, after it had moved to a swankier uptown address, early members of The Hansa included Jean Follett, Barbara Forst, Miles Forst, Wolf Kahn, Allan Kaprow, Felix Pasilis, Richard Sankiewicz, Jacques Beckwith, and Jane Wilson. Wilson's husband, the composer and writer John Gruen, served as the co-op's first Program Director, despite his inexperience in the art world.
