Landscape architect Warren Henry Manning (1860–1938) was one of the most influential practitioners in the profession’s nascent years. Horticulturist, landscape architect, town and city planner, and author, Manning was mentored by Frederick Law Olmsted and went on to practice in almost every state in the country, tallying more than 1,700 diverse projects in his fifty-year career. Hundreds of these properties still survive. Among other notable achievements, Manning was a founding member of the American Society of Landscape Architects, trained several influential landscape architects of the twentieth century, and developed a method of site analysis that was later refined by Ian McHarg to form the basis of today’s computer-aided design (excerpted from Library of American Landscape History, Inc., http://www.lalh.org/manningrp.html, accessed February 2011)
