Jacques Gréber

[4] Following graduation in 1908,[3] he left for the United States, where American architects who had trained at the École hired him to help design French gardens for the large houses they built in New England.

These include Harbor Hill (1910) in Roslyn on Long Island, New York for Clarence Mackay with architects McKim, Mead & White); and at Lynnewood Hall (1913) in Elkins Park, Pennsylvania for Peter A.

Gréber was appointed to the faculty of the Institute of Urbanism in Paris and was active in the reconstruction and expansion plans of a number of French cities in the interwar period.

[6] Following the war, Gréber was invited by Prime Minister of Canada William Lyon Mackenzie King to return to Ottawa and continue his work on a master plan for the city and surrounding region that he had started from 1937 to 1939.

This included a "Great Marble Court" surrounded on 3 sides by arcades (with each arch representing a U. S. state) and a pavilion at its center to house the Liberty Bell.

In France, between the world wars, Gréber worked on urban plans in Lille, Belfort, Marseille (1930), Abbeville, and Rouen, Neuilly, Montrouge,[10] among others.
