Josef Müller-Brockmann. Eine Brücke in die Zukunft. Zürich: Migros, 1955
“Müller-Brockmann believed that initial attempts at employing a grid system, along with a striving for maximum order and economy in the use of typographic resources, could already be discerned in the thirties, while it took until the latter half of the forties before the first printed matter was actually designed based on a grid; he was, however, unable to name an initiator (...) One hypothesis is that Max Bill came up with the first genuine grid system in the late thirties. Afterwards this design principle was consistently developed further by Bill as well as by Richard Paul Lohse, Hans Neuburg, Josef Müller-Brockmann and others.”
