He was a professor emeritus at Claremont McKenna College and Claremont Graduate University, and a distinguished fellow of the Claremont Institute. Robert P.

He has been published in the Claremont Review of Books, the Review of Politics, National Review, and the New York Times. His most famous work, Crisis of the House Divided: An Interpretation of the Issues in the Lincoln-Douglas Debates, written in 1959, has been described as "the greatest Lincoln book ever".Jaffa was a formative influence on the American conservative movement, challenging notable conservative thinkers, including Russell Kirk, Richard M. Weaver, and Willmoore Kendall, on Abraham Lincoln and the founding of the United States. He debated Robert Bork on American constitutionalism. He died in 2015.
