The geometry of Paul Renner’s sans letterforms was tempered by optical correction to follow earlier typeface proportions, with capitals close to old-style forms, yet still retaining the spirit of the New Typography. His early experimental characters were included as alternatives in the sans which was to become the Futura released by Bauer in 1927–30. Unusually, old style figures also appeared in his early versions but they too were soon discarded. Foundry Architype Renner as a new four weight family has been developed from the original Renner Regular and Bold, created by The Foundry for the first Architype Collections in the early 1990s. This new family features the old style figures and the experimental elements.
