In 1919, the Bauhaus manifest was not in geometric sans serifs but it was in an art nouveau form. Later Herbert Bayer and Joost Schmidt re constructed the type to a geometric type feel.
Herbert Bayer created the design for Bauhaus typeface in 1925. Bauhaus took place during the reform revolution in the 1920’s. The typeface is based on geometric shapes and sizes. Bauhaus is a san serif font meaning it does not have any lines tailing from the edges of the letters. Bauhaus is designed round by the edges not like Helvetica, which is straight giving it a modern abstract feel to the typeface.
