1875–1973
A pioneering clinical psychologist, she helped shape some of the early tools used to study language, intelligence, and mental illness. Her work linked careful testing with real-world hospital practice at a time when psychology was still defining itself.

Grace Helen Kent was an American clinical psychologist born on June 6, 1875, in Michigan City, Indiana, and she died in 1973. She is best known for her major role in developing the Kent-Rosanoff Free Association Test, an influential word-association test designed to help distinguish patterns of thought in psychiatric patients.
She studied at Grinnell College, earned bachelor's and master's degrees in psychology from the University of Iowa, and also studied at Harvard and at the Philadelphia Hospital for the Insane. Over the course of her career, she worked at institutions including Kings Park State Hospital, Worcester State Hospital, and Danvers State Hospital, where she developed and refined psychological tests for both adults and children.
Kent's career stands out for its practical spirit: she focused on tests that clinicians could actually use in hospitals and clinics, not just in research settings. In addition to her association test, she contributed to form-board and intelligence testing, and she continued teaching and clinical work even after her formal retirement.
