How was Alan Greenspan connected to Ayn Rand and the Collective?

Alan Greenspan was a prominent member of the "Collective," an inner circle of intellectual followers that gathered at Ayn Rand’s apartment to discuss her philosophy and review drafts of her work, such as Atlas Shrugged.1

After meeting Rand in 1952, Greenspan became a dedicated member of her inner circle and embraced the principles of objectivism, including the advocacy of radical self-interest and laissez-faire capitalism. His association with the group began during the period when Rand’s followers, including Nathan and Barbara Branden, were actively engaging with her ideas and promoting her work.21

While Greenspan later achieved significant public influence as an economist and chairman of the Federal Reserve, his early intellectual development was deeply shaped by his participation in this group and his commitment to Rand's philosophical framework.12
