Ethel Tobach (November 7, 1921 – August 14, 2015)^[1] was an American psychologist known for her work in comparative and peace psychology.^[2][3]

Tobach was born on November 7, 1921, in Miaskovka, Ukrainian Soviet Socialist Republic, which was then part of the Soviet Union. Both of Tobach's parents were Jewish, which led to them and their daughter having to flee the country to avoid pogroms soon after Tobach was born. They initially fled to Palestine, but after Tobach's father died when she was nine months old, she and her mother moved to Philadelphia in the United States. Tobach and her mother lived in Philadelphia until they moved to Brooklyn, New York when Tobach was ten years old. She became interested in psychology after enrolling at Hunter College in 1937. She received her B.A. from Hunter College in 1949, graduating Phi Beta Kappa. She then enrolled at New York University (NYU), where she received her M.A. in 1952 and her Ph.D. in 1957 under the supervision of T. C. Schneirla.^[2][4]

After taking one of Schneirla's comparative psychology classes at NYU, in which she got an A, Tobach persuaded Schneirla to give her a job at the American Museum of Natural History. She would continue to work at the American Museum of Natural History for the rest of her career.^[4] During her career, she also served on the faculty of NYU, Hunter College, the CUNY Graduate Center, and Yeshiva University.^[5]

Tobach received the Society for the Psychological Study of Social Issues' Kurt Lewin Award, the society's most prestigious award, in 1993. In 2003, she received the APA's Gold Medal Award for Life Achievement in Psychology in the Public Interest.^[4]

Tobach married Charles Tobach, a photojournalist, in 1947; he subsequently persuaded her to apply to the Ph.D. program in psychology at NYU.^[7] She died in her sleep on August 14, 2015, in Wayland, Massachusetts.^[1]
