Philip Guston was a Canadian-born, American artist. Guston was known for his involvement in the New York School, during a time of transition form Abstract expressionism to Neo-expressionism. Rather than painting in a purely abstract manner, Guston preffered to render objects in a cartoon-like fashion.

Guston was born with the name, Phillip Goldstein, in Montreal Canada. As a child, Guston moved with his family to Los Angeles, California. Guston’s family constantly faced anti-semetic persecution and were the victims of Klan activities. When Guston was still young he found his father dead after comitting suicide behind their family house. A few years after the traumatizing incident, Guston enrolled at the Los Angeles Manual Arts High School. It was at this point that Guston was first exposed to art and studied along other future artists such as Jackson Pollock.

Guston earned a scholarship to study at Otis Art Institute of Art, but left after only year of study. Guston was unsatisfied with the academic approach and use of plaster casts over live models. At the age of eighteen, Guston painted a political mural about the Scottsboro Boys. The mural was controversial among law enforcers and soon defaced. Guston’s political and socail interests continued to grow, and in 1936 Guston moved to New York to work as an artist for a WPA program.

During the 1940s Guston started working as a teaching-artist. From 1941-1945 Guston became an artist-in-residence, first at the State University of Iowa and then at Washington University in Missouri. After this point Guston began to teach at New York University, Pratt Institute and Boston University.

Guston continued to create mainly abstract paintings until the 1960s. At this point he shifted towards more representational and cartoon-like paintings. Guston first exhibited his new paintings at the Marlborough Gallery, New York in 1970. The show was highly criticized, despite the praise of fellow artist, Willem de Kooning.

After the exhibit, Guston decided to leave New York City and relocate upstate in Woodstock. Guston spent the rest of his life in Woodstock where he made his last and most remebered series. His latest works included images of shoes, clocks, cigarettes and Klan symbols. Guston’s works are now highly valued in collections around the world.
