Ruth Smith Lloyd (January 17, 1917 – February 5, 1995) was a 20th-century scientist whose research focused on fertility, the relationship of sex hormones to growth, and the female sex cycle. She earned a PhD in the field of anatomy from Western Reserve University in 1941, making her the first African-American woman to have reached this achievement.[1] Lloyd worked on the faculty of medicine at Howard University from 1942 to 1977. She married physician Sterling Morrison Lloyd in 1939, and they had three children: Marilyn, Sterling and David. She died of cancer in 1995.

Early life and education[edit]

Ruth Smith was born in Washington, DC on January 17, 1917.[2] Her parents were Mary Elizabeth (Morris) Smith, who was a clerk in the US Treasury Department, and Bradley Donald Smith, who was a pullman porter.[2] She had two sisters named Hilda B, and M Otwiner.[3][4] She was the youngest child.[5] Lloyd attended the prestigious, historically black, Dunbar High School.[2][3]

Lloyd attended Mount Holyoke College, which was then a mostly white institution.[6] Her choice of college was reportedly influenced by the experience of her brother-in-law, William Montague Cobb, who was married to Hilda.[2] Lloyd graduated with a bachelor of arts cum laude in 1937, majoring in zoology.[2][7]

From 1937 to 1938, Lloyd studied for a master's degree in zoology at Howard University supported by a fellowship, under Ernest Everett Just.[2] She had planned on becoming a school teacher, but was encouraged to undertake further study.[5] Lloyd gained a fellowship from the Rosenwald Fund and undertook doctoral studies under Boris Rubenstein at Western Reserve University in Cleveland, Ohio.[2] She studied the fertility of macaque monkeys,[8] becoming the first African-American woman to gain a PhD in anatomy with her dissertation, Adolescence of macaques (Macacus rhesus) in 1941.[9][2]

Career[edit]

Lloyd taught at Hampton Institute in Virginia from 1941 to 1942, and then joined the medical faculty of Howard University in 1942.[2][5][3] Lloyd worked at Howard until her retirement in 1977.[5][3] She taught physiology and anatomy, reaching the rank of associate professor in 1955.[2] Her areas of research were endocrinology, sex-related hormones, and medical genetics.[5] Lloyd also chaired the university's Committee on Student Guidance and was director of the Academic Reinforcement Program.[2][3] From 1947, the Department of Anatomy in which she worked was chaired by William Montague Cobb.[10]

She was a member of Sigma Xi honorary scientific society and the American Association of Anatomists.[3]

Personal life[edit]

Ruth Smith married Sterling Morrison Lloyd in on December 30, 1939.[3][2] He was a physician who also graduated from Howard University, who died in 1980.[2][3] Lloyd had three children and eight grandchildren.[3][2] In retirement, she was active in the All-Souls Unitarian Church, helped found the National Museum of Women in the Arts in 1987, and was a member of the social and service organization, Girl Friends.[2][3]

Lloyd died of cancer at home in Washington on February 5, 1995.[3]
