The couple had no children, but were friends with some college students and young professionals, including Nathaniel Branden (who later wrote psychology books, including important works on self-esteem), Alan Greenspan (economist, who was Federal Reserve chairman for the United States government) and Leonard Peikoff (later author of philosophy works, and editor of Rand's works). O'Connor "played host" to many discussions and forums about human interaction, relationships and societies, while wife Rand led the conversations.
