 In the spirit of reductive minimalism, Bayer developed a crisp visual style and adopted use of all-lowercase, sans serif typefaces for most Bauhaus publications.Bayer is one of several typographers of the period including Kurt Schwitters and Jan Tschichold who experimented with the creation of a simplified more phonetic-based alphabet.From 1925 to 1930 Bayer designed a geometric sans-serif "Proposal for a Universal Typeface" that existed only as a design and was never actually cast into real type.
