Dr. Ruth Lloyd was known as the first African American woman to acquire her doctorate degree in Anatomy. She started her work in pursuing a degree in zoology, then doctoral research where she studied the fertility of female Macaque monkeys. She taught Anatomy and Physiology in 1955. During this, she studied endocrinology, sex-related hormones, and medical genetics. She was an active member of the Sigma Xi Honorary Scientific Society and the American Association of Anatomists. Outside of her work, she was very dedicated to the All Souls Unitarian Church in Washington. All of her contributions, including being a charter member of the National Museum of Women in Arts, serve as a basis for researchers today.
