This
hydronym, which was formalized in 1935 by the Quebec Geographical Commission, evokes the work of life of
Michel-Delphis Brochu (
Saint-Lazare-de-Bellechasse, Quebec, 1853 - Quebec, 1933), doctor and professor at the Faculty of Medicine of
Laval University. Aliéniste, Brochu acts at the beginning of the twentieth century as general director of the asylum of Beauport, establishment named afterwards "Hospital Saint-Michel-Archangel", then designated "Hospital Center Robert-Giffard" (French: Centre hospitalier Robert-Giffard) which is named today
Institut universitaire en santé mentale de Québec (French). He is also known to have been the promoter of the First Congress of French-Speaking Doctors in America held in Quebec City, at
Château Frontenac, in 1902, as well as the first president of the Association of French-Speaking Doctors of North America. The toponym "Lac Brochu" was formalized on December 18, 1986, by the
Commission de toponymie du Québec. == Notes and references ==
