Rachel Louise Carson (May 27, 1907 – April 14, 1964) was an American marine biologist, writer, and conservationist whose sea trilogy (1941–1955) and book Silent Spring (1962) are credited with advancing marine conservation and the global environmental movement.
Carson began her career as an aquatic biologist in the U.S. Bureau of Fisheries, and became a full-time nature writer in the 1950s. Her widely praised 1951 bestseller The Sea Around Us won her a U.S. National Book Award, recognition as a gifted writer, and financial security. Its success prompted the republication of her first book, Under the Sea Wind (1941), in 1952, which was followed by The Edge of the Sea in 1955 — both were also bestsellers. This sea trilogy explores the whole of ocean life from the shores to the depths.
Late in the 1950s, Carson turned her attention to conservation, especially some problems she believed were caused by synthetic pesticides. The result was the book Silent Spring (1962), which brought environmental concerns to an unprecedented share of the American people. Although Silent Spring was met with fierce opposition by chemical companies, it spurred a reversal in national pesticide policy, which led to a nationwide ban on DDT and other pesticides. It also inspired a grassroots environmental movement that led to the creation of the U.S. Environmental Protection Agency. Carson was posthumously awarded the Presidential Medal of Freedom by President Jimmy Carter.
Carson was born on May 27, 1907, on a family farm near Springdale, Pennsylvania, located by the Allegheny River near Pittsburgh. She was the daughter of Maria Frazier (McLean) and Robert Warden Carson, an insurance salesman. She spent a lot of time exploring around her family's 65-acre (26 ha) farm. An avid reader, she began writing stories, often involving animals, at age eight. At age ten, she had her first story published. She enjoyed reading St. Nicholas Magazine, which carried her first published stories, the works of Beatrix Potter, the novels of Gene Stratton-Porter, and in her teen years, Herman Melville, Joseph Conrad, and Robert Louis Stevenson. The natural world, particularly that of the ocean, was the common thread of her favorite literature. Carson attended Springdale's small school through tenth grade, and then completed high school in nearby Parnassus, Pennsylvania, graduating in 1925 at the top of her class of 44 students. In high school, Carson was said to have been somewhat of a loner.
Carson gained admission to Pennsylvania College for Women, now Chatham University, in Pittsburgh, where she originally studied English but switched her major to biology in January 1928. She continued contributing to the school's student newspaper and literary supplement.
She was admitted to graduate school at Johns Hopkins University in Baltimore in 1928, but was forced to remain at the Pennsylvania College for Women for her senior year due to financial difficulties. In 1929, she graduated magna cum laude. In the summer of 1929, Carson moved to Woods Hole, Massachusetts for a course at the Marine Biological Laboratory (MBL). While at MBL, Carson wrote a "detailed anatomical study of the brain and cranial nerves of a turtle". Her time at MBL had a profound impact on Carson, who later stated that her "first prolonged contact with the sea [was] at Woods Hole", where she "first discovered the scientific literature of the sea". That fall, she continued her studies in zoology and genetics at Johns Hopkins. After her first year of graduate school, Carson became a part-time student, taking an assistantship in Raymond Pearl's laboratory, where she worked with rats and Drosophila, to earn money for tuition. After false starts with pit vipers and squirrels, she completed a dissertation on the embryonic development of the pronephros (urinary organ) in fish.
In June 1932, she earned a master's degree in zoology. She had intended to continue for a doctorate, however in 1934 Carson was forced to leave Johns Hopkins to search for a full-time teaching position to help support her family during the Great Depression. In 1935, Carson's father died suddenly, worsening their already critical financial situation and leaving Carson to care for her aging mother.
At the urging of Mary Scott Skinker, her undergraduate biology mentor, Carson secured a temporary position with the U.S. Bureau of Fisheries, where she wrote radio copy for a series of weekly educational broadcasts called Romance Under the Waters. The series of 52 seven-minute programs focused on aquatic life and was intended to generate public interest in fish biology and the bureau's work, a task that several writers before Carson had not managed. Carson also began submitting articles on marine life in the Chesapeake Bay, based on her research for the series, to local newspapers and magazines. Carson earned extra money as a lecturer at the University of Maryland's Dental and Pharmacy Schools and Johns Hopkins University.
Carson's supervisor, pleased with the success of the radio series, asked her to write the introduction to a public brochure about the fisheries bureau; he also worked to secure her the first full-time position that became available. Sitting for the civil service exam, she outscored all other applicants and, in 1936, became the second woman hired by the Bureau of Fisheries for a full-time professional position, as a junior aquatic biologist.
Using her research and consultations with marine biologists as starting points, she wrote a steady stream of articles for The Baltimore Sun and other newspapers. However, her family responsibilities further increased in January 1937 when her older sister died, leaving Carson as the sole breadwinner for her mother and two nieces.
In July 1937, the Atlantic Monthly accepted a revised version of an essay, The World of Waters, that she originally wrote for her first fisheries bureau brochure. Her supervisor had deemed it too good for that purpose. The essay, published as Undersea, was a vivid narrative of a journey along the ocean floor. It marked a major turning point in Carson's writing career. Publishing house Simon & Schuster, impressed by Undersea, contacted Carson and suggested that she expand it into a book. Several years of writing resulted in Under the Sea Wind (1941), which received excellent reviews but sold poorly. In the meantime, Carson's article-writing success continued with her features appearing in Sun Magazine, Nature, and Collier's. Carson attempted to leave the Bureau (by then transformed into the United States Fish and Wildlife Service) in 1945. However, few jobs for naturalists were available, since most money for science was focused on technical fields in the wake of the Manhattan Project.
In mid-1945, Carson first encountered the subject of DDT, a revolutionary new pesticide—lauded as the "insect bomb" after the atomic bombings of Hiroshima and Nagasaki—that was only beginning to undergo tests for safety and ecological effects. DDT was one of Carson's many writing interests at the time, but editors found the subject unappealing; she published nothing on DDT until 1962.
Carson rose within the Fish and Wildlife Service, and in 1945 was supervising a small writing staff. In 1949, she was appointed chief editor of publications, which allowed her increased opportunities for fieldwork and freedom in choosing her writing projects; however, it also entailed increasingly tedious administrative responsibilities. By 1948, Carson was working on material for a second book and decided to begin a transition to writing full-time. That year, she took on a literary agent, Marie Rodell; they formed a close professional relationship that would last the rest of Carson's career.
Oxford University Press expressed interest in Carson's book proposal for a life history of the ocean, spurring her to complete by early 1950 the manuscript of what would become The Sea Around Us. Chapters appeared in Science Digest and The Yale Review, which published a chapter, "The Birth of an Island," which won the American Association for the Advancement of Science's George Westinghouse Science Writing Prize. Beginning in June 1951, nine chapters were serialized in The New Yorker.
