Several years later, when DC Comics introduced the concept of the Multiverse, the Silver Age Wonder Woman was situated as an inhabitant of Earth-One, while the Golden Age Wonder Woman was sited on Earth-Two. It was later revealed, in Wonder Woman #300, that the Earth-Two Wonder Woman had disclosed her secret identity of Diana Prince to the world, and had married her Earth's Steve Trevor.
The I Ching era had an influence on the 1974 Wonder Woman TV movie featuring Cathy Lee Crosby, in which Wonder Woman was portrayed as a non-superpowered globe-trotting super-spy who wore an amalgam of the Wonder Woman and Diana Prince costumes. The first two issues of Allan Heinberg's run (Wonder Woman vol. 3, #1–2) include direct references to I Ching, and feature Diana wearing an outfit similar to that which she wore during the I Ching era.
In 1944, Gaines and Marston signed an agreement for Wonder Woman to become a newspaper strip, syndicated by King Features. Busy with the newspaper strip, Marston hired an 18-year-old student, Joye Hummel, to help him write comic-book scripts. Joye Hummel, now Joye Kelly, turned 90 this April; in June, she donated her collection of never-before-seen scripts and comic books to the Smithsonian Libraries. Hiring her helped with Marston’s editorial problem, too. Her stories were more innocent than his. She’d type them and bring them to Sheldon Mayer, Marston’s editor at DC, she told me, and “He always OK’d mine faster because I didn’t make mine as sexy.” To celebrate syndication, Gaines had his artists draw a panel in which Superman and Batman, rising out of the front page of a daily newspaper, call out to Wonder Woman, who’s leaping onto the page, “Welcome, Wonder Woman!”
Olive Byrne met Marston in 1925, when she was a senior at Tufts; he was her psychology professor. Marston was already married, to a lawyer named Elizabeth Holloway. When Marston and Byrne fell in love, he gave Holloway a choice: either Byrne could live with them, or he would leave her. Byrne moved in. Between 1928 and 1933, each woman bore two children; they lived together as a family. Holloway went to work; Byrne stayed home and raised the children. They told census-takers and anyone else who asked that Byrne was Marston’s widowed sister-in-law. “Tolerant people are the happiest,” Marston wrote in a magazine essay in 1939, so “why not get rid of costly prejudices that hold you back?” He listed the “Six Most Common Types of Prejudice.” Eliminating prejudice number six—“Prejudice against unconventional people and non-conformists”—meant the most to him. Byrne’s sons didn’t find out that Marston was their father until 1963—when Holloway finally admitted it—and only after she extracted a promise that no one would raise the subject ever again.
