The Atlas Society (TAS) is an American 501(c)(3) nonprofit organization that promotes the philosophy of Ayn Rand. It is part of the Objectivist movement that split off from the Ayn Rand Institute in 1990 due to disagreements over whether Objectivism was a "closed system" or an "open system". David Kelley is the founder of TAS, and Jennifer Grossman is its current CEO.
