This is the man who created my favorite superhero. He had an incredibly fasinating life, and I would strongly recommend reading The Secret History of Wonder Woman by Jill Lepore to learn more about him and his famous heroine. After reading it, I realized that every story about Wonder Woman's creation that I'd seen/read in the past was an oversimplification. Dr. Marston was a man who was ahead of his time and yet wouldn't have quite fit in our time, either.
Fun fact: He invented the lie detector (hence why he chose to give Diana of Paradise Island a lasso of truth).
