St. Elmo Society at Yale was founded in 1889 as a chapter of the national fraternity Delta Phi, and it is today one of the “ancient eight consortium” of secret societies at the university. The society’s original building was erected in 1895 and provided housing, meeting spaces, a library, smoking room, and other recreational spaces for the members. Just over a decade later, the group’s increasing wealth and membership necessitated a larger building. This building, named St. Elmo Hall was designed by architect Kenneth MacKenzie Murchison in an Elizabethan style and built in 1912 for the society, replacing its former residence hall. The society saw dwindling funding and during World War II, St. Elmo Hall became a convalescent hospital for soldiers who were out of the hospital but still need observation. After WWII, the group began leasing some rooms out to Yale University, who eventually purchased the building in 1962, renaming it Rosenfeld Hall after Richard Rosenfeld ’63. The L-shaped building is sited opening up to the corner lot and is Neo-Gothic in style, likely drawing inspiration from Yale’s established Gothic stylistic influence.
