Aaron Director was the key figure in the formative years of Chicago antitrust analysis. Although he didn’t write much himself his thoughts were transmitted through a legion of famous students including Robert Bork (before Bork became cranky) and Richard Posner. George Stigler once said “most of Aaron’s articles have been published under the names of his colleagues.” Director also founded the very influential Journal of Law and Economics which he co-edited with Ronald Coase.
Director is Rose Friedman’s older brother. When Rose was to marry Milton he gently teased that he was not in favor because Milton was too supportive of the New Deal! Appreciations from Don Boudreaux, the Washington Post, and the University of Chicago.
