Christiana Drummond Morgan (born Christiana Drummond Councilman; 1897–1967) was a lay psychoanalyst at Harvard University best known for her work co-authoring the Thematic Apperception Test, one of the most widely used projective psychological tests. She administered one of the earliest versions of the test to one of the first diagnosed anorexic patients in Boston. She is mostly remembered as the lover of American psychologist Henry Murray. The nude portrait statue of Morgan commissioned by Murray from Gaston Lachaise is now owned by the Governor’s Academy, Byfield, Massachusetts.
