Robert C. Morris was active in Cheyenne in the 1880s serving as stenographer for the district court and private secretary to Governors Hale, Warren, and Richards. Robert Morris was responsible for grants for the Carnegie libraries in Green River and Cheyenne, acquiring the land for the State Miscellaneous and Law Library, and the free county library system. He also founded the Wyoming State Historical Society and was the organization's secretary.
Construction of the current building started in 1919 and the Stanley Hotel and Isis Theater opened in 1921. Apart from the theater the hotel had space for three other businesses. The Isis Theater remained open until the Star Twin opened on Uinta Drive. Today the marquis of the Isis Theater can still be seen on the building.
