Lt.-Colonel The Hon. Jean-Georges-Barthélemy-Guillaume-Louis Gugy (January 1770 – July 17, 1840) represented Saint-Maurice in the Legislative Assembly of Lower Canada and the Legislative Council of Lower Canada. In his early years at Trois-Rivières he was Justice of the Peace, Colonel of the militia and Sheriff. On entering politics he came to Montreal where he was appointed Sheriff and was elected the first president of the Montreal Mechanics' Institution (now the Atwater Library of the Mechanics' Institute of Montreal). He inherited five seigneuries from his uncle, Conrad Gugy.
Known as Louis Gugy, he was born in 1770 at Paris. He was the son of Colonel Barthélemy Gugy (1737-1797), and his Swiss-French Huguenot wife, Jeanne Elizabeth Teissier de la Tour (who died at an advanced age in Montreal), the granddaughter of Antoine de Teissier (b.1667), 1st Baron of Marguerittes in the Languedoc. Though Swiss and the son of an officer in the Dutch service, Louis's father had joined the armies of the King of France. He served with distinction, was knighted, and at the breaking out of the French Revolution, was Colonel commandant of the 2nd Regiment of Swiss Guards in the French Royal Service, that corps being the personal bodyguards of King Louis XVI during the revolution.
