Stewart Lee Udall, Secretary of the U.S. Department of the Interior under Presidents Kennedy and Johnson, in 1963 published The Quiet Crisis, a book that provided a history of the American conservation movement, discussed the degradation of the nation's natural resources, and called for more responsible stewardship in the future. Issued the year after Rachel Carson’s Silent Spring, it became a New York Times bestseller widely reviewed in the popular press and in scientific journals. Most of the book drew on Udall’s reading of history and memoir, but the penultimate chapter, titled "Conservation and the Future," relied on seven reports published in 1962 by the Committee on Natural Resources of the National Research Council-National Academy of Sciences at President Kennedy's request and on a massive independent study produced by the Resources for the Future think tank. Udall concluded that science and technology were positive forces for resource conservation, an assertion he later regretted when, as an attorney in private practice, he litigated cases seeking compensation from the government for the harm caused to individuals by nuclear bomb testing fallout and uranium mining. Historian Byron Pearson has characterized Udall’s tenure at Interior as a period of pragmatic political deal-making with the U.S. Congress that relied more on rhetoric than on scientific and technical data (Still the Wild River Runs, 2002). In this paper, I will evaluate the ways in which Udall interpreted and used the National Academy of Sciences and Resources for the Future information in The Quiet Crisis in an effort to begin to understand the network of print that influenced American environmental policy of the 1960s.
