Sigmund Freud is one of the most important historical figures of psychology, as he is the creator of psychoanalysis (a technique used to study the unconscious mind). Although he passed away in 1939, his work is still studied and highly regarded today. Sherman quotes some of Sigmund Freud's writings and ideas in this video here.
