The Henry B. and Caroline Clarke/Bishop Louis Henry and Margaret Ford House or Clarke-Ford House is a Greek Revival style home, now serving as a house museum in Chicago, Illinois, United States. Built around 1836, it is considered the oldest existing house built in Chicago. Henry Brown Clarke was a native of New York State who had come to Chicago in 1833 with his wife, Caroline Palmer Clarke, and his family. He was in the hardware business with William Jones and Byram King, establishing King, Jones and Company, and provided building materials to the growing Chicago populace. The house was built by a local contractor, probably John C. Rue, who later married the Clarkes' housemaid, Elizabeth (Betsy) Saunders.
