Just weeks before Dunglison and his wife arrived in the United States, Jefferson had written to Joseph C. Cabell that an anatomical theater would be "indispensable to the school of anatomy," and that "there cannot be a single dissection until a proper theater is prepared giving an advantageous view of the operation to those within, and effectually excluding observation from without." This structure, which was eventually demolished in 1938, was one of the first of its kind in the entire United States, conceived and blueprinted by Jefferson himself, who pushed fervently for its construction up until the time of his death in 1825.
