After twenty-five years of far-ranging fieldwork, Eleanor J. Sterling knows the full spectrum of Earth’s waterways well—a knowledge she amply poured, as curator, into the exhibit entitled “Water: H2O= Life" at the American Museum of Natural History, November 3, 2007 through May 26, 2008. Her expertise on one particular river, the Mekong, shaped her co-authorship, with Martha Maud Hurley and Le Duc Minh of the book Vietnam: A Natural History. (Yale University Press, 2006). She currently directs the Center for Biodiversity and Conservation at AMNH and teaches at Columbia University in New York.
