Thomas C. Leonard is a distinguished historian and professor at Princeton University, where he specializes in the intersections of economics, social policy, and American intellectual history. With a keen eye for the undercurrents of reform movements, Leonard's scholarship illuminates the complex and often troubling legacies of progressivism in shaping modern America. His seminal work, Illiberal Reformers: Race, Eugenics, and American Economics in the Progressive Era, meticulously uncovers how early 20th-century economists and policymakers intertwined scientific racism and eugenics with economic theory, challenging romanticized views of the Progressive Era. Drawing on extensive archival research, Leonard's writing bridges academic rigor with accessible narrative, offering profound insights into the ideological foundations of inequality and reform. A frequent contributor to leading historical journals, he continues to influence debates on the ethical dimensions of economic thought.
