The Swiss type designer Adrian Frutiger decisively influenced the international creation of typefaces after 1950. His Univers typeface and the machine-readable font OCR-B are milestones, as is his type for the Paris airports, which evolved into the Frutiger typeface. All set new standards for signage types. In all, he created some fifty types, including Ondine, Méridien, Avenir, and Vectora.
