Marston was in a polyamorous relationship with his wife Elizabeth, a psychologist and inventor in her own right, and Olive Byrne, a former student who became an academic. This relationship was key to the creation of Wonder Woman, as Elizabeth and Olive's feminist ideals were ingrained in the character from her creation.
