Superman débuted in 1938, Batman in 1939, Wonder Woman in 1941. She was created by William Moulton Marston, a psychologist with a Ph.D. from Harvard. A press release explained, “ ‘Wonder Woman’ was conceived by Dr. Marston to set up a standard among children and young people of strong, free, courageous womanhood; to combat the idea that women are inferior to men, and to inspire girls to self-confidence and achievement in athletics, occupations and professions monopolized by men” because “the only hope for civilization is the greater freedom, development and equality of women in all fields of human activity.” Marston put it this way: “Frankly, Wonder Woman is psychological propaganda for the new type of woman who should, I believe, rule the world.”
