Mercy Hospital was located at 1030 West Munson Street when it was built and opened in 1925, according to Susie Foster, a nurse from the inception of this facility. The building was constructed by the Sons and Daughters of Mercy, a fraternal organization of African-American citizens.  Mercy cared for the African Americans in Denison.

Dr. R. C. Riddle was supreme President and hospital director, and his assistant was Dr. Holloway. When Dr. Riddle moved away in 1946, the hospital was purchased by Dr. U. C. Franklin, who continued its operation for a number of years before turning it into the Haven Rest Home until 1971, when the hospital finally closed.

Dr. Riddle died in 1950 in Benton Harbor, Michigan.  His body was shipped back to Denison for burial in Magnolia Cemetery
