marquis de Charles Casaux

Often listed in old catalogs as Charles, marquis de Casaux, he is also identified in major library and reference records as Alexandre Casaux or Alexandre Cazeau de Roumillac. Sources agree that he lived from 1727 to 1796, and describe him as a French writer whose work moved across economics, politics, and public affairs.

Reference records and biographical summaries describe him as a military man, colonial planter, economist, and politician, with links to the physiocratic current of eighteenth-century economic thought. He was also associated with the Royal Society, and his work circulated in both French and English.

Among his best-known works is Thoughts on the Mechanism of Societies, a study of national debt, taxation, and wealth that focused closely on England. The surviving record around his title and personal background is a little tangled, so the safest picture is of a prolific late-Enlightenment author whose books joined economic theory to urgent practical questions about government and society.
