Martin Franklin Hanley built the Historic Hanley House in 1855.  The farmstead is the oldest structure in the City of Clayton and it is listed on the National Register of Historic Places.  The restored home is today an historic house museum filled with original family furnishings, artifacts, and letters that together represent an honest portrayal of 19th century Missouri life.
