Beatrice M. Hinkle (1874-1953) was an American writer, psychologist, and pioneer in psychical research. She studied under the renowned psychologist William James at Harvard University and developed a deep interest in the human unconscious and spiritual phenomena. Hinkle made significant contributions to the field of psychology in early 20th-century America through her translations of European psychological works and her own writings on mental exploration. As a female scholar in a male-dominated field, she broke barriers and established herself as an important figure in American psychological and psychical research movements.
