Gréber was born in Paris, the son of sculptor Henri-Léon Gréber, and attended the École des Beaux-Arts in that city.[3] He was a fine student and won several prizes during his training at the École.[4]
As his reputation as a landscape architect began to spread, Gréber won his first public commission for the Fairmount Parkway (now Benjamin Franklin Parkway) in Philadelphia. While completing the parkway, he was also commissioned by the French government to make a systematic study of American construction practice. This would form the basis for his influential book Architecture in the United States (French: L'Architecture aux États -Unis)[4]
He returned to France in 1919, where he secured a reputation as one of France's leading urban designers. 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.[4]
World War II
During World War II, Gréber remained in Vichy France and became president of the French Society of Urbanists (French: Société française des urbanistes). As a designated spokesperson for the cause of urbanism in France, he contributed to a collection of essays in which he lauded the Vichy government for providing an orderly national planning program and centralized planning institutions. He was a prominent member of the urban planning hierarchy that oversaw the urban renewal projects of the Vichy government, and was appointed as Inspector General for Urbanism (French: inspecteur générale de l'urbanisme) in Northern France, a position requiring the consent of the Nazi Oberfeldkommandantur.[6]
Postwar Activities
Following the war, Gréber was invited by Prime Minister of CanadaWilliam 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.[6][4]
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.
Gréber is best known for the 1917 master plan for the Benjamin Franklin Parkway in Philadelphia;[7] 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.[8] 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.[9] 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,[10] among others. But he is not as well-known today in France as he is in North America.
