A predecessor club for 700 DuPont employees (1924) on the grounds of the Experimental Station was displaced by expansion of that facility in the 1940s. By 1949, there were 4,300 club members, and New York architect Embury's new building was said to be the largest country club in the nation. The 400-foot facade showed the stripped classicism then popular, with a porticoed entry of brick piers modern-looking in its simplification. Inside was a long hall, known as Peacock Alley. The golf course (1946–1947, Alfred H. Tull) was extensively refurbished in 2004.
