Google has created a doodle to mark the 107th birthday of environmentalist author Rachel Louise Carson.
The internet giant has devised one of its iconic illustrations to commemorate the birthday of the American marine biologist and conservationist, whose book Silent Spring is credited with advancing the global environmental movement.
The doodle features a tall, slim woman, presumed to be Carson gazing across a lake into the middle distance.
She has a pair of binoculars about her neck and her elegant neckerchief flutters in a stiff breeze.
A multitude of flora and fauna can be seen, including a seal, a pelican, a tern, a butterfly and a wading bird of some description.
Born in Springdale, Pennsylvania on May 27, 1907, Carson began her career as a marine biologist in the US Bureau of Fisheries and became a full-time nature writer in the 1950s.
She wrote three best-selling books about the ocean, entitled The Sea Around Us, The Edge of the Sea and Under The Sea Wind before turning her attention to conservation, especially environmental problems that she believed were caused by man-made pesticides.
The result was 1962′s Silent Spring, which led to a nationwide ban on DDT and other pesticides and inspired a grassroots environmental movement that led to the creation of the US Environmental Protection Agency.
Carson died in Silver Spring, Maryland on April 14, 1964 at the age of 56.
She was posthumously awarded the Presidential Medal of Freedom by Jimmy Carter.
