The William R. and Martha Foster Shriver House is a historic residence located in Winterset, Iowa, United States. William R. Shriver was an Ohio native who settled in Jefferson County, Iowa before he moved to Madison County in 1853–54. He married Martha Foster in 1858 in Winterset. He was a wagon-maker by trade, and served as a lieutenant in the 1st Iowa Cavalry during the American Civil War. Shriver went into farming in the 1870s, and they left this house at that time. He went on to serve as the Clerk of District Court from 1882 to 1887. The Shrivers left Iowa for California in 1890 because of Martha's health. She died there that same year, and William returned to Iowa permanently in 1900.
