Maxwell Maltz (1889-1975) was an American cosmetic surgeon, author, and pioneer in the field of self-development and applied psychology. Trained as a medical doctor and practicing plastic surgery for many years, Maltz became fascinated by the profound psychological changes he observed in patients after physical reconstruction. These insights led him to explore the connection between self-image, behavior, and personal achievement, which he ultimately synthesized in his self-help classic Psycho-Cybernetics.
