Molly Harrower (born Mary Rachel Harrower; January 25, 1906 – February 20, 1999) was an American clinical psychologist. During the Second World War she created a large-scale multiple choice Rorschach test. She was one of the first clinical psychologists to open a private practice. Specializing in diagnostics, Harrower developed a scale allowing practitioners to predict which patients would profit from psychotherapy.
