Peter Gnass was born in Germany and attended the Hamburg Academy of Fine Art and the École des beaux-arts de Montréal, then specialized in printmaking under Dumouchel. In 1970, he presented his first solo exhibition at the Musée d’art contemporain de Montréal, Topolog. During his career, he has had regular exhibitions in Canada and abroad, and he has produced a number of works of public art. In 1967, he created a bronze mural for the lobby of Théâtre Maisonneuve de Montréal, and in 1978 he created a large stainless-steel mural for the LaSalle Métro station.
Inspired by the sunlight admitted by the clerestory windows overhead, Peter Gnass created this huge, inclined stainless-steel structure, 3.3 metres deep in places, to reflect the light and the movements of the crowd.
