William Moulton Marston

William Moulton Marston was a renowned psychologist, inventor, and comic book writer, best known for creating the character Wonder Woman. He held a Ph.D. in Psychology from Harvard and was a professor at American University. His diverse career reflected his interest in understanding and depicting human behavior.

Marston developed the DISC theory in the 1920s, focusing on four primary emotions and associated behavioral responses.

His work emphasized understanding emotional behavior to better manage people and relationships, laying the groundwork for the modern DISC assessments used in various sectors today.
