The sculptor Augustus Saint-Gaudens modeled an 1884 bronze portrait plaque of Mitchell. Mitchell commissioned Saint-Gaudens to create a monument to his deceased daughter Maria: The Angel of Purity, a white marble version of the sculptor's Amor Caritas. Originally installed in Saint Stephen's Church, Philadelphia, it is now at the Philadelphia Museum of Art.
