The Mary Foust Residence Hall, designed by Harry Barton of Greensboro, North Carolina, opened in 1927-1928. In 1928, the building was named in honor of Mary Robbins Foust Armstrong (Class of 1920) who was the daughter of President Julius Isaac Foust. She died unexpectedly in 1925 and the Alumnae Association recommended that the building be named in her honor.
