Stained-glass window by Marcelle Ferron, at Champ-de-Mars metro station in Montreal
One of her stained-glass windows is at Champ-de-Mars metro station in Montreal. It was one of the first non-figurative works to be installed in the metro, in defiance of the didactic style present in other works of the period, and signalled a major shift in public art in Montreal between the policies of then art director Robert Lapalme and future art director and fellow automatiste Jean-Paul Mousseau. Other examples of her works can be seen at Vendôme metro station, Hôpital Sainte-Justine, and the ICAO headquarters, in Montreal; the Place du Portage in Gatineau, Quebec; and the Granby, Quebec courthouse.In 1983, she was awarded the Paul-Émile-Borduas medal for the visual arts by the government of Quebec. In 1985, she was made a Knight of the National Order of Quebec and was promoted to Grand Officer in 2000. She was a member of the Royal Canadian Academy of Arts.She died in Montreal.Wikipedia
