Sara Gwendolen Foulke

Sara Gwendolen Foulke (26 June 1863 – 13 December 1936) was an American zoologist, marine biologist and poet. She worked on microscopic water inhabiting animals and her obituary described her work as "genius."

Biography
Foulke was born at Bala Farm, Chester County, Pennsylvania, to Julia DeVeaux Powel (daughter of John Hare Powel) and her husband, William Parker Foulke. She was initially educated at private schools and subsequently attended Bryn Mawr College and the University of Pennsylvania. Further into her career she studied and undertook research at Woods Hole Oceanographic Institution and at the Station biologique de Roscoff.

During the 1880s, Foulke focused her research on infusoria and rotifers, microscopic water inhabiting animals. She published a number of scientific articles on the subject. She also assisted Edward Potts by providing scientific illustrations for his publication Fresh water sponges; a monograph. Later she became interested in investigating the behaviour and form of protoplasm. In 1897, Foulke published an article titled The Living Substance as such, and as Organism in the Journal of Morphology. This article was initially criticised. Later in life Foulke developed an interest in child and animal psychology. However, by the time of her death, this work was regarded by her obituary writer Henry Van Peters Wilson, as a work of "genius".

Death and publication of her book of poetry
Foulke died on 13 December 1936 at the age of 73 due to a heart attack at her home in Baltimore. After her death, her husband published her poems in a two volume set under her pseudonym Richard De Veaux.

Family
In 1894 Foulke was married to biologist Ethan Allen Andrews. The couple had three children.
