Samuel Pufendorf’s first nautral law work Elementorum Jurisprudentiae Universalis was published in 1660. This representation demonstrates that his ideas of natural law, including political economy, were taken over and used extensively by the most important British and French philosophers. In France, many philosophers used Pufendorf’s works as a major source when they developed their own doctrines. John Locke was the first scholar of any importance who actively used Pufendorf’s natural law works when he developed his own theories. Pufendorf’s natural law works were Jean-Jaques Rousseau’s primary source. An anonymous referee has claimed that everyone knew Pufendorf and his contribution to the history of economic thought. The investigation claims that Pufendorf’s contribution to political economy is of such importance that while Adam Smith unquestionably is considered the father of modern political economy, Samuel Pufendorf deserves to be remembered as the grandfather.
