Helen Thompson Woolley

Helen Bradford Thompson Woolley (November 6, 1874 – December 24, 1947) was an American psychologist, known for her contributions to the educational sector, research on sex differences and research methods. Woolley's interest in scientific inquiry was prompted by the work of her father, Paul Thompson, who was an inventor. Woolley's academic achievement and resultant scholarship allowed her to pursue studies in psychology at the University of Chicago.

Woolley's university studies marked the beginning of her career in experimental and applied psychology. Her controversial dissertation, titled The Psychological Norms in Men and Women, attracted the interest and the scrutiny of the scientific world as it was the first major piece of psychological research explicitly examining the similarities and differences of the mental traits of women and men.

Woolley's husband, Paul Woolley, was a determining force in the course of her career, as the constant relocations required by his profession as a physician limited her academic opportunities. Following their wedding, Woolley followed Paul to Japan and subsequently the Philippines, where she started working as a researcher for the Bureau of Education, marking her first endeavour in developmental psychology. Woolley's work in education continued with her involvement in the Vocation Bureau, the Merrill-Palmer School and the Institute for Child Welfare Research at Teachers College, Columbia University.

Woolley's late life was plagued by her deteriorating mental health, which impacted her interpersonal relationships as well as occupational status. At the age of 73, she died of an aortic aneurysm at her daughter's home in Havertown, Pennsylvania.
