What was the date that wonder woman was created?

Wonder Woman was the first female Superhero.

And she was a new kind of superhero, one who would triumph not with fists or firepower, but with love. She was created to be a model of that era's (1940's) unconventional, liberated woman.

The creator (William Marston) was also the creator of a systolic blood-pressure measuring apparatus, which was crucial to the development of the polygraph (the lie detector). Marston's experience with polygraphs convinced him that women were more honest and reliable than men, and could work more efficiently. In Marston's mind, women not only held the potential to be as good as men: they could be superior to men.

In a 1943 issue of The American Scholar, Marston wrote: "Not even girls want to be girls so long as our feminine archetype lacks force, strength, and power. Not wanting to be girls, they don't want to be tender, submissive, peace-loving as good women are. Women's strong qualities have become despised because of their weakness. The obvious remedy is to create a feminine character with all the strength of Superman plus all the allure of a good and beautiful woman."
