Patrick Courrielche
In 2015, Courrielche wrote a long form story "St. Nicholas: The Birth Of A Social Weapon" on the origin of Santa Claus and introduced the concept of a "social weapon" - a packaged idea, message, or product that is used by an individual or group to advance their cause. Courrielche argued that New York City elites crafted Santa Claus from St. Nicholas, a widely known patron saint, to stabilize a city plagued by annual misbehavior every December. Santa Claus was then used as a "social weapon" by merchants, craftsman, city rulers, parents, newspapers, and others to benefit their endeavors. The essay was added to the St. Nicholas Center's resource on the Origin of Santa Claus.
Mrs. Claus
Since 1889, Mrs. Claus has been generally depicted in media as a fairly heavy-set, kindly, white-haired elderly female baking cookies somewhere in the background of the Santa Claus mythos. She sometimes assists in toy production, and oversees Santa's elves. It is worth noting that, when not portrayed as white-haired or elderly, she is often shown to have red hair. This could be because red hair is the color that most commonly fades to white with age. She is usually depicted wearing a fur dress of red or green.
