Career
After taking a Bachelor of Science from Chicago in 1913 and an Doctor of Medicine in 1916, Greenacre worked for some years under Adolf Meyer on experimental psychology. She began psychoanalytic training in 1937, and thereafter rose to high prominence within the ranks of the American psychoanalytic establishment, before finally retiring at the age of ninety. Greenacre highlighted the voyeuristic elements in the writing of Lewis Carroll, as well as distortions of body image with respect to Lemuel Gulliver.
