Considered one of the most important painters of the 20th century, Clyfford Still (1904-1980) was among the first generation of Abstract Expressionist artists who developed a new and powerful approach to painting in the years immediately following World War II. After the artist's death in 1980, the Clyfford Still Estate was sealed off from public and scholarly view. In August 2004, the City of Denver, was selected by Still's wife, Patricia Still, to receive the substantial Still collection. In 2005, Patricia Still also bequeathed to the city her own estate, which included select paintings by her husband as well as his complete archives. The Still Museum collection, which represents nearly 94 percent of the artist's lifetime output, includes approximately 2,400 works created between 1920 and 1980. The Clyfford Still Museum is the newest addition to Denver's burgeoning Cultural Arts District and is located adjacent to the Denver Art Museum in the city's Civic Center Cultural Complex.
