Phil Lewis

University of Wisconsin Landscape Architecture Professor Emeritus Phil Lewis is on MySpace. His book, on the other hand, is starting to get scarce.

You can see how Fitchburg WI has their Regional Design guidelines online based on his work.
Here is a local blog writing about Phil Lewis' work.  You can see a great photo of one of his large models. The Wisconsin Idea Center features a classic Lewis-ian diagram. 

Perhaps the continuing relevance of his ideas is reflected in the fact that students still write about him.
