William Fett (1918–2006) was an American-born painter who spent much of his career in Mexico, where he developed a distinctive style blending Romanticism, Surrealism, and landscape painting. Born in Ann Arbor, Michigan, he studied at the School of the Art Institute of Chicago, graduating in 1941 before traveling to Mexico on a fellowship. This experience profoundly shaped his artistic vision. Fett became known for his luminous watercolor landscapes of Mexican terrain, often infused with abstract, biomorphic, and surreal elements. During the 1940s, his work was exhibited in New York and acquired by major institutions, including the Museum of Modern Art. He was associated with a circle of exiled Surrealist artists working in Mexico. He later taught for decades at Washington University in St. Louis, while increasingly distancing himself from the commercial art world to pursue a more personal, independent practice.
