b. 1835
A sharp-eyed American naturalist, she turned close observation of plants and insects into lively science writing that reached a wide audience. Her work on carnivorous plants and her exchanges with Charles Darwin helped earn her a lasting place in the history of natural history.

by Samuel Wells, Frederick Leroy Sargent, Mary Treat
Born on September 7, 1830, Mary Treat was an American naturalist, botanist, entomologist, and writer. She is remembered for careful, hands-on studies of the natural world at a time when women were often excluded from formal scientific careers.
Treat wrote widely about insects, plants, and birds, blending patient observation with an easy style that made science approachable. She became especially known for her work on carnivorous plants in New Jersey, and she corresponded with Charles Darwin, who took her research seriously.
Over the course of her career, she published popular and scientific writing and built a reputation as an independent investigator. She died on April 11, 1923, leaving behind a body of work that still stands out for its curiosity, clarity, and persistence.
