Philip H. Lewis Jr.

After the death of his wife, Lewis lived at Middleton Glen in the new-urban planned community of Middleton Hills. This traditional neighborhood in the City of Middleton, Wisconsin was developed by his long-time friend Marshall Erdman. A street in Middleton Hills is named after Lewis. Lewis resided at Waunakee Manor, Waunakee, Wisconsin, before he died on July 2, 2017. On September 12, 2013 the Dane County, Wisconsin Board of Supervisors dedicated a Madison E-Way to Lewis, to be known as the Lewis Nine Springs E-Way. The title recognizes the work of Lewis and his wife, Elizabeth (Libby), who served for 26 years on the Dane County Parks Commission.

Lewis contributed to the origins of geographic information systems technology with his application of maps using transparent overlays for environmental planning. The Environmental Systems Research Institute (Esri) presented Lewis with its Lifetime Achievement Award in 2000.

Lewis celebrated his retirement from the University of Wisconsin at a banquet on April 22, 1995.

Lewis was a visiting professor in the School of Design at Harvard University from 1976 to 1977.

Lewis became the founder and director of the Environmental Awareness Center, part of the School of Natural Resources and the College of Agriculture and Life Sciences. Lewis had joint appointments with the Department of Landscape Architecture, Department of Urban & Regional Planning, and the University of Wisconsin–Extension. Lewis also served as chair of the UW Landscape Architecture Department from 1964 to 1972 and taught undergraduate and graduate design courses. Shortly before his retirement in 1995 he served as the Jens Jensen Professor of Landscape Architecture.

Lewis was the director of the Recreation and Open Space Study of Illinois from 1958 to 1961. Here he identified environmental corridors and landscape personalities that were used to guide planning efforts. He was recruited by Wisconsin Governor Gaylord Nelson to serve as the Director of the State of Wisconsin Recreation Resource, Research and Design, Department of Resource Development, where he served from 1963 to 1965. Environmental corridors were again identified in the Wisconsin State Recreation Plan to help guide planning decisions in the state.

On June 13, 1953, Lewis married Elizabeth Alice Thompson, a botany student at Radcliffe College. They were married for 58 years until her death on February 1, 2012.

After returning from Europe, Lewis worked for the University of Illinois Bureau of Community Planning from 1953 to 1963. He taught City Planning Research with visiting professor Patrick Horsbrugh in the spring of 1957. Horsbrugh and Lewis became lifelong friends and colleagues.

Lewis completed a summer internship with the National Park Service in 1952, where he learned about governmental agency interdisciplinary efforts to maintain the landscapes under their jurisdiction. His thesis focused on the Everglades Inventory and Development Study.

After working at the Goetz Nursery, he attended Harvard Graduate School of Design, (1950–1953), where he earned a master's degree in landscape architecture.

Lewis graduated from Lawrenceville Township High School in 1943. He enlisted in the Army Air Force upon graduation and completed a six-month training program at Hondo Air Base in Hondo, Texas, where he received navigation training. He completed his service with the Army Air Force in 1946. He attended the University of Illinois on the G.I. bill, receiving a bachelor's degree in landscape architecture in 1950. Influential figures during his undergraduate training included Stanley Hart White and Karl B. Lohmann. His education at the University of Illinois culminated in a trip to California to view contemporary landscape architecture projects with his favorite teacher, Hideo Sasaki. This trip included tours of gardens that had been designed by Thomas Dolliver Church and Garrett Eckbo. Following this trip, Lewis secured his first professional job as a landscape architect with the O. E. Goetz Nursery in Webster Groves, Missouri.

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".

Lewis was born in Robinson, Illinois (20 miles from his hometown of Lawrenceville, Illinois), United States, on September 4, 1925. His father, Philip Howard Lewis Sr. (1890–1971), was an attorney who was a county judge and a state's attorney (1924–1930). His mother, Florence Sutfin Lewis (1900–1998), was a homemaker who worked at the First National Bank in Lawrenceville, Illinois. He had a younger sister, Gretchen.
