During the final days of the Civil War, Dr. William Ward and his wife, Eliza Ward, envisioned a school for young women in Nashville that would evolve into one of the nation's most prestigious institutions. As the New South dawned, Ward Seminary opened its doors in September 1865. Merging with Belmont College for Young Women in 1913, Ward-Belmont operated as a college preparatory school, music conservatory, and junior college. In 1951, the high school division moved farther west, reopening as the Harpeth Hall School after Ward-Belmont's sudden closure. Ward Seminary, Belmont College, Ward-Belmont, and Harpeth Hall are simply separate chapters of one continuous story. As Harpeth Hall celebrates 150 years, its story reflects a unique case study and provides a lens through which to understand the evolution of all-girls education in the United States. The Harpeth Hall School remains one of the oldest all-girls college preparatory schools in the South.
