Philip H. Lewis Jr.

Philip Howard Lewis Jr. (September 4, 1925 – July 2, 2017) was an emeritus professor of landscape architecture who promoted the "environmental corridor" concept. He taught for more than 40 years at the University of Illinois (1953–1963) and the University of Wisconsin–Madison (1964–1994). Charles Little, author of Greenways for America, describes Lewis as the "...most inventive (and occasionally controversial) figure in regional landscape planning theory in the country".
