Born in Albuquerque on Oct. 8, 1915, Luna Leopold was the second son of Aldo and Estella (Bergere) Leopold. In 1948, Aldo died soon after hearing that Oxford University Press planned to publish A Sand County Almanac. Fortunately, Luna saw to it that the manuscript became a book, and now we have one of the most important books of the ecological movement. Like his father, Luna was a brilliant scientist with successful careers in both government and academia. Awarded his doctorate in geology from Harvard in 1950, he spent 22 years with the U.S. Geological Survey and then joined the faculty at UC Berkeley. In Luna’s obituary, the New York Times called his 1964 book, Fluvial Processes in Geomorphology, seminal. Other important works include Water: A Primer (1974) and A View of the River (1994). He was awarded the National Medal of Science in 1991. In 1996, David Rosgen dedicated his book Applied River Morphology to “Luna B. Leopold, whose wise counsel and teaching have benefited many, and whose exemplary contributions have advanced science and promoted the river ethic.” He died in Berkeley, Calif. on Feb. 23, 2006.
