Considered a member of the first generation of Bay Area Figuration, weeks’ work is characterized by a signature “flattened” style, bold outlining of brilliant color fields, and aggressive, interlocking shapes. His influences range from European Modernists Henri Matisse and Max Beckmann to California Modernist Maynard Dixon and Mexican muralist Clemente Orozco.
Weeks studied at the California School of Fine Arts, which later became the San Francisco Art Institute. In 1943, he enlisted in the Army Air Forces. After World War II, he returned to the California School of Fine Arts, studying under the charismatic instructors David Park and William Gaw.
His monumental figural compositions and landscapes from the 1950s and sixties are prized for their clarity, articulation, and balance between color and form. Weeks is associated with the Bay Area figurative painters, but unlike his peers—David Park, Elmer Bischoff, and Richard Diebenkorn-he never publicly experimented with non-objective painting. By 1960, Weeks unique style had fully emerged and works from this time are highly sought-after by curators and collectors.
