d. 1815
A French naval officer, political figure, and writer, he moved between science, public life, and the sea. His surviving work includes practical and speculative writing on navigation, winds, and maritime reform.

by Antoine Poissonnier-Desperrières, chevalier de La Coudraye
Born in Fontenay-le-Comte in 1743, the chevalier de La Coudraye — François-Célestin de Loynes de La Coudraye — was a French naval officer who also built a career as a writer and public figure. Records describe him as both a man of the navy and an author, and he later served as a deputy to the Estates-General in 1789.
His books reflect a strong interest in maritime questions. He wrote on subjects such as determining longitude at sea, the theory of winds and waves, and the provisioning of sailors, showing the mix of scientific curiosity and practical naval experience that shaped his work.
La Coudraye died in Saint Petersburg on November 15, 1815. Though not widely known today, he stands out as one of those late eighteenth-century figures whose writing connected seafaring, technical inquiry, and public debate.
