[Scleroderma and Paul Klee: Metamorphosis of life and art?].

Paul Klee was born in 1879 in Münchenbuchsee, not far from Bern, and died at the age of 60 in Switzerland due to severe scleroderma, which was diagnosed in 1936. From this time on, this connective tissue disease had followed him continuously and had strongly influenced his enjoyment of life, personal development and creative power in art work, before finally causing his death in 1940. Based on diaries, letters, personal remarks and notes, his case history was reconstructed from the first symptoms to the date of diagnosis up until his death and an analysis was made of the influence his illness had on his art work in aura, color, figure and productivity.
