# Mary Terrall

Mary Terrall (April 10, 1952 – September 11, 2023) was an American academic and science historian. She specialized in the 18th century.

## Biography

Born in Sharon, Connecticut on April 10, 1952, Terrall earned a Bachelor of Arts from Harvard University and a doctorate from the University of California, Los Angeles.
The central theme of Terrall's research is the science of the 18th Century. She wrote articles on the various subjects of scientific culture in Berlin during the time of Frederick the Great and French science in the Age of Enlightenment. She also took an interest in vis visa, a theory at the origin of the laws of conservation of energy. She notably wrote a book and several articles on Pierre Louis Maupertuis, a French philosopher, mathematician, physicist, astronomer, and naturalist of the 18th Century who contributed to the various theories of Isaac Newton and formulated the stationary-action principle. Maupertuis also led the French Geodesic Mission to the Equator.
Terrall also described and analyzed the way Maupertuis used literary techniques to recount his expedition to Lapland in the form of an adventure story, so as to interest a wider audience. She wrote an article describing his use of anonymity when publishing controversial work, though presenting it as neutral. Additionally, she took an interest in the work of René Antoine Ferchault de Réaumur and the way in which he and other naturalists used literary techniques to tell narratives on animal behaviors.
In 2003, Terrall received the Pfizer Award from the History of Science Society for The Man Who Flattened the Earth: Maupertuis and the Sciences in the Enlightenment. She was awarded the Gottschalk Prize from the American Society for Eighteenth-Century Studies for the same work in 2004. She was the 1998 recipient of the Margaret W. Rossiter History of Women in Science Prize, awarded by the History of Science Society for her 1995 article "Emilie du Châtelet and the Gendering of Science," after having received the Derek Price Award in 1994 (now the Price/Webster Prize) for the "Representing the Earth’s Shape: The Polemics Surrounding Maupertuis’s Expedition to Lapland."
Mary Terrall died on September 11, 2023, at the age of 71.
