Laszlo Moholy-Nagy (1895-1946). One of the great photographers and graphic designers (including typographical designs) of the Bauhaus movement.
I highly recommend checking out graphic design images (especially posters) from the Bauhaus era. Many of them are incredible and definitely have inspired what may still be called radical design today. Especially in terms of typography. Also look at Constructivist Design.
(Constructivism came right after the Bauhaus movement...it's easy to see why. It definitely vibed off of the Bauhaus movement. Lots of black and white and red and gray. Mayhaps a post on this soon.).
