Zapf was concerned that this was the wrong way to go, and while he was interested in creating a complicated program, he was worried about starting something new. However, Zapf remembered a page of calligraphy from his sketchbook from 1944, and considered the possibility of making a typeface from it. He had previously tried to create a calligraphic typeface for Stempel in 1948, but hot metal composition was too limiting on the freedom of swash characters. Such a result could only be achieved using modern digital technology, and so Zapf and Siegel began work on the complicated software necessary. Siegel also hired Gino Lee, a type designer from Boston, Massachusetts, to render the extensive character set. (The "ino" in "Zapfino" refers to Gino.)
