Rachel Louise Carson (May 27, 1907 – April 14, 1964) was an American marine biologist, author, and conservationist whose book "Silent Spring" and other writings are credited with advancing the global environmental movement.
The Rachel Carson National Wildlife Refuge is a 9125 acre National Wildlife Refuge made up of several parcels of land along 50 mi of Maine's southern coast.
 Created in 1966, it is named for environmentalist and author Rachel Carson, whose book "Silent Spring" raised public awareness of the effects of DDT on migratory songbirds, and of other environmental issues.
Henry Graham Greene (2 October 1904 – 3 April 1991), better known by his pen name Graham Greene, was an English novelist regarded by many as one of the great writers of the 20th century.
 Combining literary acclaim with widespread popularity, Greene acquired a reputation early in his lifetime as a major writer, both of serious Catholic novels, and of thrillers (or "entertainments" as he termed them).
 He was shortlisted, in 1966 and 1967, for the Nobel Prize for Literature.
 Through 67 years of writings, which included over 25 novels, he explored the ambivalent moral and political issues of the modern world, often through a Catholic perspective.
Dangerous Edge: A Life of Graham Greene is a biographical documentary film about Graham Greene, originally broadcast nationally on PBS on March 29, 2013 and distributed internationally.
 It was directed by Thomas Patrick O'Connor and narrated by Derek Jacobi.
 Contributors and cast include Graham Greene himself, his wife Vivien Greene, Bernard Diederich, John le Carré, David Lodge, John Mortimer, Bill Nighy, John Perkins, Paul Theroux and biographers Richard Greene (no relation) and Norman Sherry.
Ruth Jury Scott (27 March 1909 – 18 June 2003) was a lifelong environmental activist, naturalist, and conservationist.
 Scott was a close friend and colleague to Rachel Carson due to their shared passion for educating others about the environment as well as the deadly effects of chemical pesticides.
 She later served on the executive committee of the Rachel Carson Trust for the Living Environment, Inc.
