From Wikipedia, the free encyclopedia
Claude Humbert Piarron de Chamousset (1717 - 1773) was a French philanthropist.
Born in Paris, he was the originator of mutual benefit societies. According to A. Piron, Du Service des Postes (1838), in 1758 he established a new postal system at Paris charging two sols for a single letter under one ounce, replacing the earlier postal system established in 1653 by Renouard de Velayer.
