LESAGE, Louis , b. 13 Aug. 1827, L'Assomption County, Que.; d. 9 Jan. 1889, Verdun, (Montreal) Que. Educated in the classics and theology at the College of L'Assomption and the Grand Seminary, Montreal and Chambly, he acquired practical architectural knowledge in Montreal in 1851, and worked for the Grand Trunk Railway surveying at Rivière du Loup. In 1853, he became T.C. Keefer's assistant on the Montreal harbour and waterworks, and, in 1856, was appointed superintendent of the Montreal waterworks, retaining that office for the next 33 years. During this time, he upgraded and enlarged the waterworks from a single system, with a daily pumping capacity of 6 million gallons, to two systems of 34 million gallons. An authority on waterworks, he advised municipalities in Que., Ont. and N.S. on their systems. A member of the American Society of Civil Engineers, and a founding member of the Canadian Society of Civil Engineers, he served on its first council in 1887. From 1880 to 1883, he was mayor of Verdun and chairman of the Board of School Commissioners.
