Inspector General for Urbanism () in Northern France, a position requiring the consent of the Nazi Oberfeldkommandantur. Postwar Activities 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 would culminate in the General Report on the Plan for the National Capital (1946–1950) or Greber Plan that would reshape the city in the postwar era. Major works Gréber is best known for the 1917 master plan for the Benjamin Franklin Parkway in Philadelphia; for his work as master architect for the 1937 Paris International Exposition; and for the Greber Plan for Ottawa and the surrounding National Capital Region. The latter, produced between 1937 and 1950 (with an interruption during the Second World War), included expansion of urban parks, a series of parkways, and a greenbelt surrounding the city. The plan incorporated the construction of a national cenotaph and surrounding plaza area. In anticipation of the 1926 sesquicentennial of the Declaration of Independence, Gréber created a plan for a mall north of Independence Hall in Philadelphia. 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. It was not carried out; Independence Mall was created in the 1950s under a different plan. He also collaborated with fellow French-American architect Paul Cret on Philadelphia's Rodin Museum in 1926. He was not always popular with the press: a Philadelphia newspaper dubbed him "Jack Grabber". In France, between the world wars, Gréber worked on urban plans in Lille, Belfort, Marseille (1930), Abbeville, and Rouen, Neuilly, Montrouge, among others. But he is not as well-known today in France as he is in North America. See also Greber Plan (Ottawa) Gatineau Park Greenbelt (Ottawa) Notes External links Web site about Clarence H.
