title: [Louis-Marie Rousseau and the "Chocolat rationnel des pharmaciens français" (Rational Chocolate of French pharmacists)].
abstract: In 1883, the chemist Louis-Marie Rousseau (1849-1930) creats the "Compagnie hygiénique française" (French Hygienic Company). The company manufactures and sells the "Poudre de viande Rousseau" (Rousseau meat powder) and the "Chocolat Rousseau" (Rousseau Chocolate) by methods developed and patented by the pharmacist. Ten years after a successful collaboration, L.-M. Rousseau separates from his associates and founds the "Chocolaterie spéciale d'Ermont" (Special Chocolate factory of Ermont) in the village of Ermont near Paris. Here is manufactured the "Chocolat Rationnel des pharmaciens français" (Rational Chocolate of French pharmacists), hygienic chocolate sold only in pharmacies. The factory is also a pharmaceutical laboratory where is extracted theobromine from waste vegetable substances of cocoa. It then produces the "Théobromine Rousseau cristallisée" (crystallized Rousseau's Theobromine) sold as tablets, then the "Théosol" that will be commercialized until the middle of 1930s.
