Completed: 1912 Architect: C.C. Hook When it first opened, the East Duke building contained offices, including the office of the President, three assembly rooms, and two parlors, later known as the Alumnae Room and the Anna Branson Memorial Room. The east and west assembly rooms on the second floor were initially the home of the two Duke literary societies, the Hesperian and Columbian Societies. Hesperia Hall was converted into the Y.W.C.A. Chapel in 1937-1938. Columbia Hall started being used as a music practice and recital room beginning in 1936-1937 and became known as the East Duke Music Room. In 1980, the room was renamed the Ernest W. Nelson Music Room, in honor of the late founder and longtime director of the Durham Chamber Arts Society.
