Paul Klee is one of the most significant artists of the twentieth century. For the nine volumes of this landmark project, the Paul Klee Foundation researched some 9,800 drawings, prints, watercolours and oil paintings to catalogue the artist's oeuvre in its entirety. Presenting Klee's output in chronological order, each volume contains an introduction, an explanation of the catalogue system, a German/English glossary, a bibliography and indexes. All of the entries include full reference material, and the vast majority are illustrated. Klee's own entries from the meticulous catalogue he kept from 1911 until his death in 1940 are also included. In 1931, after terminating his teaching contract with the Bauhaus, Klee took up a professorship atthe Dusseldorf Academy of Art. Two years later, however, he came under attack from the Nazis and was dismissed, whereupon he went to live in Switzerland. Klee's work during 1931-33 reflects his further travels, to Sicily, Venice and the South of France.
