The psychodynamic approaches to therapy are primarily based on the theories of Freud. Sigmund Freud is considered the father of psychoanalysis, a method of therapy that emphasizes the importance of unconscious processes and childhood experiences in shaping behavior and personality. Freud's work laid the foundation for various therapeutic techniques used in psychodynamic therapy, including free association, dream analysis, and the exploration of transference and countertransference in the therapeutic relationship.

In contrast, the other figures mentioned, such as Carl Rogers, Aaron Beck, and Albert Ellis, are associated with humanistic therapy, cognitive therapy, and rational emotive behavior therapy, respectively. While these approaches also provide valuable insights into mental health treatment, they do not form the basis of psychodynamic theory. Thus, the correct answer is Freud.
