Following a brief discussion of his early life and college years, Jonathan Seybold talks in detail about the work that his father, John W. Seybold, and he did in promoting the development and implementation of computerization in the printing and publishing industries, beginning in the 1960s. They first joined efforts to run the company, ROCAPPI, which was a pioneer in digital typesetting and hyphenation and justification (H&J) technologies. Jonathan then became the leading communicator for desktop publishing technology and the evangelist for the nascent desktop publishing industry. Jonathan worked as an industry consultant and founded Seybold Publications. He also founded Seybold Seminars, which grew into large, bicoastal gatherings and trade shows for both industry users and vendors. These forums were instrumental in promoting and disseminating information about the use of desktop publishing technologies during the 1980s and 1990s.
