At the age of 17, Leonard Peikoff was invited to the home of Ayn Rand, the novelist and Objectivist philosopher. Thus began a friendship that lasted until her death in 1982. Today, Dr. Peikoff is Rand's legal and intellectual heir - and the world's foremost authority on Objectivism.

Renowned philosopher, Dr. Peikoff is the author of Objectivism: The Philosophy of Ayn Rand and The Ominous Parallels: The End of Freedom in America. He has edited numerous Ayn Rand anthologies and has recently published a new book, The DIM Hypothesis, which deals with the role of epistemology in cultural and practical affairs.
