Artressia Davis, now 95, died after several unsuccessful attempts to sue the proprietors of both the Missouri Caverns and Onondaga Cave in 1943. In 1945, Bradford's widow, Mary Bradford, sold Onondaga to the Barnard Hospital. For the first time since its discovery, Onondaga now had only one owner. A director of the hospital, Charles Rice, took control of the now-joint caverns as well as Cathedral Cave and, free of the financial and legal problems that had plagued the caves since their discovery, began to further develop them under the management of Al Bryan. The electrification of the rural area of the state allowed the entire cave to be wired for lighting, and the old tour paths were replaced with new trails, stairs, and bridges. These improvements continued after Rice's death in 1949.
