Joseph Marsh Sheridan studied at Beloit College, ASL in NYC, and the AIC. He taught English and dramatics in Quincy and in Roswell, NM, until 1928 when he abandoned this line of work to concentrate solely on art. He was an art instructor at the University of Minnesota (1929-30) and in 1931 moved to Berkeley where he studied with Hans Hofmann at UC. He established a studio in Berkeley and in 1933 he studied with Archipenko at Mills College. In the mid-1940s he worked in the art departments of the Unviersity of Arizona and Westminster College in Wilmington, PA. Working in watercolor and tempera, his works are often abstract, smbolic, or strongly influenced by Cubism.
