About the artist:

Klee was born on December 18, 1879, in Münchenbuchsee, near Bern, Switzerland, the second child of Hans Klee, a German music teacher, and a Swiss mother. His training as a painter began in 1898 when he studied drawing and painting in Munich for three years. By 1911, he had returned to that city, where he became involved with the German Expressionist group Der Blaue Reiter (The Blue Rider), founded by Wassily Kandinsky and Franz Marc in 1911. Klee and Kandinsky became lifelong friends, and the support of the older painter provided much-needed encouragement. Until then, Klee had worked in relative isolation, experimenting with various styles and media, such as making caricatures and Symbolist drawings, and later producing small works on paper mainly in black and white. His work was also influenced by the Cubism of Pablo Picasso and Georges Braque, and the abstract translucent color planes of Robert Delaunay He visited Tunisia in 1914. In 1920, Walter Gropius invited Klee to join the faculty of the Bauhaus. A school of architecture and industrial design operating first in Weimar (1919–25) and then Dessau (1925–32), it also included the study of arts and crafts. Nearly half of Klee's some 10,000 works (mainly small-scale watercolors and drawings on paper) were produced during the ten years he taught at the Bauhaus, and they vary widely. Some relate to the subject of his courses, to his preoccupation with the relationship of colors, such as Static-Dynamic Gradation, produced in 1923 . In the same year, Klee painted Ventriloquist and Crier in the Moor , which, with its humor and grotesque fantasy, may strike many viewers as the quintessential "Klee." Klee developed his own often whimsical world of line and color, rich in symbolism and the expression of his vision of society. He taught from 1920 to 1931 at the Weimar Bauhaus and then at Dessau's Bauhaus. It was during this time that he met Kandinsky. While Klee's work showed the influence of constructivist tenets, it never lost the humane element which made it seem much freer. From 1931 to December 1933, Klee taught at the Academy of Fine Arts in Düsseldorf. When the National Socialists declared his art "degenerate" in 1933, Klee returned to his native Bern. Personal hardship and the increasing gravity of the political situation in Europe are reflected in the somber tone of his late work. Lines turn into black bars, forms become broad and generalized, scale larger, and colors simpler, as in Comedians' Handbill or Angel Applicant.
