This volume brings together three papers from a symposium on the work of Robert Heilbroner, along with additional essays. Former students and colleagues from Europe, North America, and Brazil reflect on the contributions of the New School economist and historian of economic thought and discuss the relationship between Heilbroner and his mentor Adolphe Lowe, Heilbroner in the context of the American debate on government spending, and his views on capitalism. The volume also includes a new essay on Karl Marx's evolutionary credentials and the intellectual relationship between Marx and John Stuart Mill, an essay on the role of eugenicist thinking among Harvard economists into the interwar period, and a new archival discovery: Richard Musgrave's reflections on Alvin Hansen and John Williams' Fiscal Policy Seminar at Harvard, from 1988.
