He is the brother of H. H. Liebhafsky, and I believe they both were at Texas-Austin, when that department had a strong institutionalist (American-style, as in Veblen-Commons tradition) flavor. They both published often in the Journal of Economic Issues. They also both were very involved in developing and promoting the pragmatist (Dewey-Peirce tradition) philosophical base for institutionalist economics. There is a very good oral tradition about their teaching and supervising of students. Mathew Forstater
