Peikoff met Ayn Rand in 1951, at age 17, after being invited to her home in California. Their friendship and professional association lasted until her death in 1982, and Rand’s ideas redirected him from pre-medical studies toward philosophy.

Peikoff’s enduring legacy is as a principal custodian and expositor of Objectivism after Rand’s death. He helped establish the Ayn Rand Institute in 1985, and his systematic presentation of the philosophy drew on a 1976 lecture course Rand publicly endorsed.
