William Moulton Marston was a psychologist and feminist, as was his wife Elizabeth Holloway Marston. They were involved in a long term polyamorous relationship with Olive Byrne, and the triad had four children - the two born to Byrne being legally adopted by the Marstons. Elizabeth continued to work even after having children, which was almost unheard of for its day, and both Marstons were prominent in the early feminist movement. William had a position as scientific adviser to the feminist magazine Family Circle. In his writings, he suggested that women were naturally more intelligent than men, and that matriarchy was the inevitable (and desirable) future of the United States. William and Elizabeth were married for thirty two years. Their relationship with Olive started in the '20s, and persisted until William’s death in 1947, after which Elizabeth and Olive continued in a relationship until the latter’s death in the '80s. Elizabeth herself died at the age of 100 in 1993.
William Marston is credited with the invention of the polygraph and (with Elizabeth’s help) the the systolic blood pressure test, but he is most famous for the creation of comic book superhero Wonder Woman.
