Google today celebrates the 107th birthday of Rachel Louise Carson, an American marine biologist and conservationist. Visitors on Google will be welcomed with a beautiful illustration which is celebratory of her life, achievements and contributions to marine biology and ecology.

The doodle shows Carson standing with a pair of binoculars around her neck and a notebook in her hand observing a rich multitude of flora and fauna including a seal, a pelican, a tern, a butterfly and a wading bird.

Rachel Carson was born on May 27, 1907 in the rural river town of Springdale, Pennsylvania. Initially she wanted to be a writer but her love of biology took her first to Chatham College and then to Johns Hopkins University for an MS in Zoology in 1932. 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 a book ,Silent Spring which was noted and credited with advancing the global movement on environment.

Her most significant work was the campaign against the use of DDT (Dichloro Diphenyl Trichloroethane), a common insecticide, in the USA. She had questioned the logic of releasing large amounts of chemicals into the environment without a sufficient understanding of their effects on ecology and human health which eventually led to the ban on agricultural use of DDT in America in 1972.

Carson died in Silver Spring, Maryland on April.
