In addition to his work with the State Fair and the FAP, Haupers was well known as an art educator. He began teaching in 1930s at the St. Paul Arts and Crafts Center and the St. Paul Gallery and School of Art and continued teaching until his death. His influence on decades of young artists was as instrumental in developing the visual arts in Minnesota as his administrative roles.[1] In 1965, Haupers was the subject of an oral history interview about the Federal Art Project,[2] and was also interviewed in 1977 and 1981 as part of the Minnesota Artists Oral History Project, transcripts of which are available online.[3][4]
