Originally known as the Lewisburg Academy, the school was founded around 1812 by Presbyterian pastor Dr. John McElhenny as a co-educational institution. For unclear reasons, the Lewisburg Academy separated into two schools, the Greenbrier Military School and the Lewisburg Female Institute, in the 1870s. The Lewisburg Female Institute (LFI) was a girls’ boarding school, and students could attend from grades 1-12. The focus of LFI changed in 1937; women could only attend for four years, two years of high school and two years of college. There was always a heavy emphasis on the arts, with the majority of students enrolled in at least music class in the early 20th century. Throughout its history, girls could take courses in a variety of subjects including math, English, history, science, Bible, music, home economics, and secretarial work. On December 16, 1901, a fire destroyed the original buildings of the LFI. Classes were held at City Hall and The Greenbrier for the remainder of the year.
