Darwin Lambert's autobiography: A lifelong odyssey toward Earthmanship, his word for the process of cooperating with Nature in order to achieve his goals of happiness and a healthy and sustainable Earth. ""Darwin's knowledge of the workings of nature, his historical perspective, and his various writings earned him a large following among near-by and national conservationists. He was a careful and thorough researcher and his broad range of local information was most helpful to me throughout my tenure at Shenandoah National Park. If Darwin were alive today, in our world of instant communication and everyday convenience, I am confident that he and Eileen would still choose to live in Shaver Hollow in their 1845 log house located at the end of a narrow, ungraded mile of bumpy road from a chained gate and their rural mailbox."" Robert R. Jacobsen, November 4, 2013 National Park Service, retired, former superintendent of Lehman Caves National Monument and Shenandoah National Park
