The Swiss designer Adrian Frutiger developed Serifa® in 1964, and it was released by the Bauer Type Foundry in 1967. He based the shapes in Serifa on those in Univers, the sans serif family he designed in the 1950s. While Serifa retains the geometric, linear skeletons of Univers, it has the addition of unbracketed square serifs, a squatter x-height, and boxier caps. Because of these characteristics, Serifa is a true representative of the slab serif (or Egyptian) style. Slab serifs designs first emerged at the beginning of the nineteenth century and have had a couple popular revivals in the twentieth century. Serifa is surprisingly elegant and legible, and with its six weights, it functions well in both text and display typography. See also Glypha, which is a condensed version of Serifa.
