PAUL KLEE (1879-1940) Attrib., Title: Untitled, Medium: Watercolor on paper, Date: Circa 1938, Size: 11.75 x 9.75 in. COA. Was a Swiss painter and important figure in the development of early 20th-century avant-garde art. KleeÂ’s breadth of subject matter ranged from his child-like portrait Senecio (1922), to the geometric landscape Castle and Sun (1928). Â“Spatial art does not begin with a poetic mood or idea,Â” he mused. Â“But with construction of one or more figures, with the harmonizing of several colors and tones, or with the devaluation of spatial relationships and so on.Â” Born on December 18, 1879 in MÃ¼nchenbuchsee, Switzerland, his love of art and music was cultivated by his family from a young age. Klee went on to study under the painters Heinrich Knirr and Franz von Stuck in Munich. By 1911, he had become a part of Munich's avant-garde milieu, which included Wassily Kandinsky, August Macke, Franz Marc, as well as other members of the Der Blaue Reiter group. Klee went on to become a professor at the fledging Bauhaus school of art and design during the 1920s. Forced to leave Germany in 1933, he was later included in the Nazi regime's infamous Â“degenerate artÂ” exhibition Â“Entartete KunstÂ” of 1937. Klee died on June 29, 1940 in Muralto-Locarno, Switzerland. Today, his works are held in the collections of the Solomon R. Guggenheim Museum in New York, the National Gallery of Art in Washington, D.C., the Tate Gallery in London, and the Kunstmuseum Basel.
