Rachel Carson (1907-64) wanted to be a writer for as long as she could remember. Her first book, Under the Sea Wind , appeared in 1941. Silent Spring , which alerted the world to the dangers of the misuse of pesticides, was published in 1962. Carson's articles on natural history appeared in the Atlantic Monthly, the New Yorker, Reader's Digest and Holiday. An ardent ecologist and preservationist, Carson warned against the dumping of atomic waste at sea and predicted global warming. The Edge of the Sea , which completed her biography of the sea, is also published in Penguin Twentieth- Century Classics. Rachel Carson died of cancer at the age of 56.
