Abstract
In this entry, we would like to show that Robert Heilbroner was not only the author of the famous best seller, The Worldly Philosophers, first published in 1953. Actually, he was an active and innovative scholar investigating many subjects, from development to finance, learning constantly on Marx, Keynes, or Schumpeter, and crossing boundaries between many social sciences. However the very core of his project remains a general inquiry on the nature and evolution of capitalism. He could be considered as a late representative of institutionalism and a brother in arm of economists like John Kenneth Galbraith, Gunnar Myrdal, or Allan Gruchy. It is in the context of this general inquiry on capitalism that Heilbroner presented his main contributions to law and economics.
