Karl Gerstnera (TM)s work is a milestone in the history of design. One of his most important works is Designing Programmes, which is presented here in a new edition of the original 1964 publication. In four essays, the author provides a basic introduction to his design methodology. Instead of set recipes, the method suggests a model for design in the early days of the computer era. The intellectual models it proposes, however, continue to be useful today. What it does not purvey is cut-and-dried, true-or-false solutions or absolutes of any kind – instead, it develops fundamental principles in an innovative and future-oriented way. The book is especially topical and exciting in the context of current developments in computational design, which seem to hold out the possibility of programmed design. With many examples from the worlds of graphic and product design, music, architecture, and art, it inspires the reader to seize on the material, develop it further, and integrate it into his or her own work.
