A tribute to an exceptional teacher and a study of the abstract visual relationships that were her lifelong pursuit. Rowena Reed Kostellow taught industrial design at Pratt Institute for more than 50 years and the designers she trained - and the designers they are training - have changed the face of American design. This volume reconstructs the series of exercises that led Kostellow's students from the manipulation of simple forms to the creation of complex solutions to difficult design problems. It includes her exercises and commentary along with selected student solutions, and concludes with examples of work from former students who became leaders in the field, including such figures as Tucker Viemeister, Ralph Applebaum, Ted Muehling, and others.
