Rachel Carson (May 27, 1907 – April 14, 1964) began her career as a biologist working with the U.S. Fish and Wildlife Service, where she later became editor-in-chief of all that department’s publications. She won lasting fame with her publication of Silent Spring in 1962, in which she documented the deleterious effects of synthetic pesticides to the environment, particularly DDT.
