FTP, name this classical revivalist architect best known for St. Mary's Cathedral in Baltimore and for redesigning the U.S. Capitol following the War of 1812.
This man's "An Overseer Doing His Duty" is among the best-known of his series of watercolors on slavery, but his southern residency is better associated with his designs for the Harvie-Gamble mansion.
