B. 1888 - Josef Albers is well known for his compositions that explore the relationships of color through a single, simple form, usually the square. In choosing the square, Albers revealed his knowledge of the work of Kasimir Malevich and Piet Mondrian, both of whom had explored the form’s spiritual and formal possibilities. Albers was also aware of the Neo-Platonic significance of the square as a pure form. His main interest, though, was in color and understanding the rules guiding visual experience, an interest that had been sparked at the Bauhaus by Paul Klee’s introductory courses, where superimposed squares demonstrated compositional and spatial effects.
