Palatino™ is the work of Hermann Zapf, and is probably the most universally admired and used of his type designs. In 1950, it was punchcut in metal by August Rosenberger at D. Stempel AG typefoundry in Frankfurt am Main, and then adapted for Linotype machine composition. Zapf optimized Palatino's design for legibility by giving it open counters and carefully weighted strokes, producing a typeface that was legible even on the inferior paper of the post-World War II period. The font was named after Giambattista Palatino, a master of calligraphy from the time of Leonardo da Vinci. Palatino is a typeface based on classical Italian Renaissance forms.
