Active at the Bauhaus between 1920 and 1931, teaching in the bookbinding, stained glass and mural-painting workshops, Paul Klee (1879-1940) brought his expressive blend of color and line to the school–and, with the second volume in the Bauhausb cher series, beyond its walls. In his legendary Pedagogical Sketchbook, Klee presents his theoretical approach to drawing using geometric shapes and lines. Evincing a desire to reunite artistic design and craft, and written in a tone that oscillates between the seeming objectivity of the diagram, the rhetoric of science and mathematics, and an abstract, quasi-mystical intuition, Klee's text expresses key aspects of the Bauhaus' pedagogy and guiding philosophies.
