Rev. Robert Palladino, whose work as a master calligrapher influenced a young Steve Jobs and subsequently the typography of Apple's first Mac computers. A Roman Catholic priest who learned the art of calligraphy as a Trappist monk, inspired the trans formative typefaces used in Apple's first machines, and by extension the modern personal computer. Prior to Mac, computers and operating systems used fonts and typesets that boasted all the artistic appeal of an IBM punch card.
