Harvard-educated psychologist, lawyer, inventor, writer, woman’s rights activist and super hero creator William Moulton Marston had a career that was impressive to say the least.

He had several claims to fame.  He developed a lie detector test in the 1920s which later evolved into the modern day polygraph.  In the 1940s he created the first female superhero – Wonder Woman – the subject of a current box office smash.

And Marston’s research and findings about the measure of human behavior and consciousness led to the theory behind the development of the DiSC profile, utilized by millions of people around the world to build more effective relationships at work and at home.
