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 tried to create a calligraphic typeface for Stempel in 1948, but hot metal composition placed too many limits on the freedom of swash characters. Such a pleasing 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 programmer from Boston, Massachusetts, to work on the project.
