Hermann Zapf designed his most famous typeface, Palatino, more than half a century ago. The drawings were completed in 1948, and by 1950 it was in use both as hand-set type and as a hot-metal typeface set on Linotype machines. In the early 1950s Zapf extended the Palatino family to include Aldus, a version designed specifically for text setting, and a pair of display variants (Michelangelo and Sistina), as well as narrow and swash italics.
