Aaron Director

Aaron Director (1901–2004) was a Russian-born American economist who founded the Law and Economics program at the University of Chicago in the 1940s, laying the institutional groundwork for what would become the Chicago School's transformation of American legal and economic thought. Director's own published work was sparse — he preferred the Socratic method of the classroom to the printed page — but his influence was transmitted through the students and colleagues he shaped, including George Stigler, Ronald Coase, and his brother-in-law Milton Friedman. Director's seminar on antitrust at Chicago systematically dismantled the structuralist assumptions of mid-century antitrust law, arguing that vertical integration, resale price maintenance, and market concentration were often efficiency-enhancing rather than competition-reducing. This seminar was the incubator for the Consumer Welfare Standard and for the Chicago School's broader project of subjecting law to economic analysis.

Aaron Director published little but colonized much. The Chicago School's intellectual empire was built in his classroom, and its weapons were forged in his seminars.
