Jacques-Henri-Auguste Gréber (10 September 1882 – 5 June 1962) was a French architect specializing in landscape architecture and urban design. He was a strong proponent of the Beaux-Arts style and a contributor to the City Beautiful movement, particularly in Philadelphia and Ottawa. Early life and education Gréber was born in Paris, the son of sculptor Henri-Léon Gréber, and attended the École des Beaux-Arts in that city. He was a fine student and won several prizes during his training at the École. Early Private Commissions Following graduation in 1908, 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. He designed many private gardens in the U.S. These include Harbor Hill (1910) in Roslyn, Long Island, New York for Clarence Mackay (with architects McKim, Mead & White); and at Lynnewood Hall (1913) in Elkins Park, Pennsylvania for Peter A. B. Widener (with architect Horace Trumbauer). His greatest private commission was for investment banker Edward T. Stotesbury at Whitemarsh Hall (1916–1921) in Wyndmoor, Pennsylvania (also with Trumbauer). There he created the unsurpassed American example of a French classical garden in the grand manner of André Le Nôtre. 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 () 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. Wartime Activities During the Second World War, Gréber remained in Vichy France and became president of the French Society of Urbanists (). 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
