Fletcher’s Sanatorium, known as Neuronhurst after 1904, was one of Indianapolis’s first private hospitals for the treatment of nervous and mental diseases in Indiana. (Norway’s Sanatorium was another early facility.) Dr. William B. Fletcher, a son of Indianapolis pioneer Calvin Fletcher, opened his private hospital in 1888 on Pennsylvania Street and eventually moved to Alabama Street in a house on the current site of the old Indianapolis City Hall (most recently used as the interim library). Fletcher worked closely with Dr. Mary A. Spink, who eventually became his business partner.
