When the members of the Committee of Public Safety are discussed, Prieur de la Côte-d’Or is usually mentioned last, if at all. Yet he was one of the founding fathers of the French Republic as we know it today. Alongside Carnot, Prieur made a major contribution to the victories of the French armies by organizing the production of saltpeter and the manufacture of weapons — a Herculean task amid revolution and war. He also helped found what would later become the École polytechnique. Prieur believed that a republic could not endure without public education. He also played a major role in introducing the metric system, a reform that still shapes our daily lives.
