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.
Santa Claus's reindeer
Rudolph's story was originally written in verse by Robert L. May for the Montgomery Ward chain of department stores in 1939, and published as a book to be given to children in the store at Christmas time. According to this story, Rudolph's glowing red nose made him a social outcast among the other reindeer. Santa Claus's worldwide flight one year was imperiled by severe fog. Visiting Rudolph's house to deliver his presents, Santa observed Rudolph's glowing red nose in the darkened bedroom and decided to use him as a makeshift lamp to guide his sleigh. Rudolph accepted Santa's request to lead the sleigh for the rest of the night, and he returned home a hero for having helped Santa Claus.
