Best known as a graphic and industrial designer, Bayer continually expressed his affinity for geometrical forms and spatial constructions. Influenced by the constructivist theories of Theo von Doesburg; Dadaist principles of collage; and by 3 Bauhaus masters: Johannes Itten, the director of the Vorkurs; Wassily Kandinsky, a teacher of analytic drawing who authored Concerning the Spiritual in Art; and the painter Paul Klee, Bayer's powerful graphic sensibility was funneled into the various disciplines that his productive career encompassed. In Germany, he was Bauhaus Master of typography and advertising from 1925-28 and from 1928-38 honed his skills in art direction. In America, Bayer served as art director of Vogue and Dorland Advertising Agency, chairman of design for the Container Corporation of America and corporate director of art for Atlantic Richfield Company.
