Robert W. Durrenberger, a professor of geography at ASU from 1971-1982, passed away on Oct. 20, 2012 at the age of 94. Durrenberger, already a nationally-known climatologist when he arrived at ASU, will be remembered at ASU for establishing the position of Arizona State climatologist at the university, as well as helping develop ASU’s climatology program into an internationally-recognized center for teaching and research. He’ll also be remembered for his research and insights into environmental challenges presented by rapid population and economic growth of the American Southwest. When he arrived at ASU in 1971, Durrenberger was well-known as a geographer with a focus on arid land research, environmental problems, agricultural geography and the U.S. southwest. He had been professor at San Fernando Valley State College (now California State University – Northridge) since 1956, where he had also served as department chair and dean of graduate studies. Durrenberger worked to establish Arizona’s State Climatology Program at ASU, and in 1973, the state named Durrenberger as Arizona’s first state climatologist. At the same time the Arizona Board of Regents also established the Laboratory of Climatology, an independent unit at ASU with a mission to serve the public, state agencies and businesses of Arizona by maintaining historical climate data for Arizona and conducting research in climate-related issues. Durrenberger held the position of Arizona State climatologist until 1979. In his role as state climatologist, he authored numerous publications specifically relevant to Arizona. After stepping down from his post as state climatologist, he focused on solar energy development, directing a project to assess Arizona’s solar energy resources and authoring a report on a solar radiation monitoring system for Arizona. While at ASU, Durrenberger published a dictionary of the environmental sciences, and played a role in a wide range of other professional activities. He served as editor-at-large for The National Weather Digest, and on the executive board of the Solar Radiation Division of the American Section of the International Solar Energy Society. Minnesota State University in Moorehead, where Durrenberger earned his undergraduate degree, presented him with its 1977 Distinguished Alumni Award, citing his contributions in education, climatology, and service to state and federal governments. He is survived by his wife of 66 years, Bernadine A. Durrenberger, a daughter, three grandchildren and two great-grandchildren. His son, Dan Durrenberger, preceded him in death.
