Lucille Farrier Stickel (January 11, 1915 – February 22, 2007) was an American wildlife toxicologist and director of the Patuxent Wildlife Research Center from 1972 to 1982. Her research focused extensively on contaminants in wildlife ecosystems and her research on the effects of the pesticide DDT helped form the basis for Rachel Carson's book Silent Spring. She was also the first woman to both become a senior scientist as a civil servant of the US government and to be director for a national research laboratory.
