In 2005, Warner Brothers announced that Joss Whedon (Buffy, Angel) would write and direct a big-screen adaptation of the Wonder Woman story in 2006. That didn't happen, but for a while, Whedon was slated to write it with another writer -- William M. Marston. He created Wonder Woman back in 1941, but was also an attorney, a psychologist, an educational consultant and an inventor. Among other things, he can claim a leading role in the development of the polygraph lie detector and the systolic blood pressure test.
Marston's psychological specialty was gender theory, and he held some views which would be as radical today as they were in the 1940s. Depending on your perspective, you might consider him a crackpot or a proto-feminist.
