Ian L. McHarg (20 November 1920 – 5 March 2001) was a Scottish landscape architect and writer on regional planning using natural systems. McHarg was one of the most influential persons in the environmental movement who brought environmental concerns into broad public awareness and ecological planning methods into the mainstream of landscape architecture, city planning and public policy. He was the founder of the department of landscape architecture at the University of Pennsylvania in the United States. His 1969 book Design with Nature pioneered the concept of ecological planning. It continues to be one of the most widely celebrated books on landscape architecture and land-use planning. In this book, he set forth the basic concepts that were to develop later in geographic information systems. Biography Formative years His father was a manager and later a salesman in the industrial city of Glasgow, Scotland. McHarg showed an early talent for drawing and was advised to consider a career in landscape architecture. His early experiences with the bifurcated landscapes of Scotland—the smoky industrial urbanism of Glasgow and the sublimity of the surrounding environs—had a profound influence on his later thinking. It was not until after his term in the Parachute Regiment, serving in war-stricken Italy during World War II, however, that he was able to explore the field of urban landscape architecture. After working with the Royal Engineers during World War II, he travelled to America. He was admitted to the school of architecture at Harvard University's Graduate School of Design where he received professional degrees in both landscape architecture and city planning in 1949. After completing his education he returned to his homeland, intending to help rebuild a country ravaged by war. In Scotland he worked on housing and programs in "new towns", until he was contacted by Dean G. Holmes Perkins from the University of Pennsylvania. Dean Perkins wanted McHarg to build a new graduate program in landscape architecture at the University. Soon thereafter, McHarg began teaching at the University of Pennsylvania, where he developed the department of landscape architecture, and developed a popular new course, titled Man and Environment in 1957. The course featured leading scholars whom McHarg invited to his class to discuss ethics and values, as well as other ideas ranging from entropy to plate tectonics. In 1960, he hosted his own television show on CBS, The House We Live In, inviting prominent theologians and scientists of
