Rachel Carson and her sisters : extraordinary women who have shaped America's environment / Robert K. Musil.

"Rachel Carson was the first American to combine two longstanding, but separate strands of American environmentalism - the love of nature and a concern for human health. Widely known for her 1962 best-seller, Silent Spring, Carson is today often perceived as a solitary great woman, whose work single-handedly launched a modern environmental movement. But as Musil demonstrates, Carson’s life’s work drew upon and was supported by already existing movements, many led by women, in conservation and public health."--Dust flap.
