software Zapf worked on typography for computer programs from the 1960s onwards. His ideas were considered radical, not taken seriously in
West Germany, and rejected by the
Technische Universität Darmstadt, where he lectured from 1972 to 1981. Because he had no success in Germany, Zapf went to the United States, where he lectured about computerized typesetting, and was invited to speak at
Harvard University in 1964. The
University of Texas at Austin was also interested in Zapf and offered him a professorship, which he did not take, because his wife opposed a move to that state. Because Zapf's plans for the United States had come to nothing, and because their house in Frankfurt had become too small, Zapf and his wife moved to
Darmstadt in 1972. In 1976,
Rochester Institute of Technology (RIT) offered Zapf a professorship in typographic computer programming, the first of its kind in the world. He taught there from 1977 to 1987, flying between Darmstadt and
Rochester. There he developed his ideas further, with the help of his connections in companies such as
IBM and
Xerox and his discussions with computer specialists at Rochester. A number of Zapf's students from this time at RIT went on to become influential type designers, including
Kris Holmes and
Charles Bigelow, who together created the
Lucida type family. Other prominent students include the calligrapher and type designer
Julian Waters and book designer
Jerry Kelly. In 1977, Zapf and his friends Aaron Burns and
Herb Lubalin founded Design Processing International, Inc., in New York and developed typographical computer software. It existed until 1986, when Lubalin died. Zapf and Burns founded Zapf, Burns & Company in 1987. Burns, also an expert in typeface design and typography, was in charge of marketing until his death in 1992. Shortly before, two of their employees had stolen Zapf's ideas and founded a company of their own. Zapf knew that he could not run an American company from Darmstadt and did not want to move to New York. Instead, he used his experience to begin the development of a typesetting program, the "
Hz-program", building on the hyphenation and justification system in
TeX. During financial problems and bankruptcy of
URW++ in the mid-1990s,
Adobe Systems acquired the Hz patent(s) and later made some use of the concepts in their
InDesign program. == Zapfino ==
