Paul Klee (December 18, 1879 – June 29, 1940) is a Swiss-born artist.
His highly individual style is influenced by movements in art that included Expressionism, Cubism, and Surrealism.
Klee is a natural draftsman who experiments with and eventually deeply explored color theory, writing about it extensively; his lectures Writings on Form and Design Theory (Schriften zur Form und Gestaltungslehre), published in English as the Paul Klee Notebooks, are held to be as important for modern art as Leonardo da Vinci's A Treatise on Painting for the Renaissance.
He and his colleague, Russian painter Wassily Kandinsky, both teach at the Bauhaus school of art, design and architecture.
His works reflect his dry humor and his sometimes childlike perspective, his personal moods and beliefs, and his musicality.
