Louis-Camus Destouches

Louis-Camus Destouches (1668 – 11 March 1726) was a French artillery officer.

He was a chevalier of the ordre de Saint-Lazare from 1690, and became a chevalier of the ordre de Saint-Louis in 1720, then commandeur in 1725. He saw a brilliant career in the artillery, gaining him the nickname 'Canon'.

Jean le Rond d'Alembert, philosophe and contributor to the Encyclopédie, was born from an affair with Claudine Guérin de Tencin in 1716. His illegitimate son was the mathematician Jean le Rond d'Alembert. Destouches secretly funded his illegitimate son's education, and left him an income of 1200 livres upon his death in 1726 in Paris.
