Jakob Erbar was a German professor of graphic design and a type designer. Erbar trained as a typesetter for the Dumont-Schauberg Printing Works before studying under Fritz Helmut Ehmcke and Anna Simons. Erbar went on to teach in 1908 at the Städtischen Berufsschule and from 1919 to his death at the Kölner Werkschule. His seminal Erbar series was one of the first geometric sans-serif typefaces, predating both Paul Renner's Futura and Rudolf Koch's Kabel by some five years.
