William Moulton Marston was an American psychologist, inventor, and author, born on May 9, 1893 in Cliftondale, Massachusetts. He gained significant recognition for his contributions to various fields, particularly in the study of behavior and emotions. Marston is most well-known for creating the fictional character Wonder Woman, who made her first appearance in 1941. Additionally, he developed the systolic blood pressure test, which formed the basis for the modern lie detector or polygraph test. Marston gained a strong reputation for his theories on human behavior, emphasizing the importance of emotions and promoting the idea that love, or what he called the “love disc,” can be a powerful influence in society. Despite his academic achievements, Marston faced controversial opinions due to his unconventional lifestyle and advocacy for women’s rights, even participating in the early 20th-century feminist movement. He passed away on May 2, 1947 in Rye, New York, leaving behind a complex legacy in the fields of psychology, comic books, and social activism.
