(With Robert Bruegmann and John Zukowsky, Art institute of Chicago, Chicago, 1979.) A catalog to accompany an exhibition at the Art Institute, this volume contains three essays by the authors. The theme of Chappell's essay, "The Enduring Power of a Plan," is the continuing influence of the ideas embodied in the Burnham Plan of 1907. In a forceful account, she illuminates the six major changes Burnham proposed for the city, and the subsequent fate of each. Analysis of what happened, what did not happen, and what may yet happen in the future accounts for the rest of the essay. In the end Chappell concludes that our great debt to Burnham includes not only what happened in Chicago, but the legacy of optimism that city planning can effect civic change. Bruegmann's brilliant essay focuses on the importance of graphic imagery in the presentation of city plans, especially in the work of Jules Guerin. Zukowsky's essay gives a thorough account of the provenance of the drawings.
