Horst W. J. Rittel (1930 – 1990) was a German-born design theorist and university professor, educated as a theroretical physicist. He is best-known (along with M. Webber) for coining the term ‘wicked problem’, but his influence on design theory and practice was also much wider. In 1963 Rittel went to Berkeley. In 1973 he also joined the University of Stuttgart in Germany.
In his work he also thought about information systems and developed a planning/design method known as IBIS (Issue-Based Information System) for handling wicked problems. With his German colleague Werner Kunz Rittel also wrote a book on the foundation of information science in Germany (Werner Kunz and Horst Rittel, Die Informationswissenschaften: ihre AnsÃ¤tze, Probleme, Methoden und ihr Ausbau in der Bundesrepublik Deutschland, MÃ¼nchen 1972).
