Turgot was a French abbot (1727-1781), Baron de l’Aulne, who after leaving the clergy became an economist and stateman, and author of the book “Reflections on the Formation and Distribution of Wealth” published in 1776. One of the great Physiocrats, and student of François Quesnay, was the first to clearly formulate the law of diminishing returns. Turgot was an early supporter of trade and economic liberalization, this being the main reason of his great influence on Adam Smith.
