Great Freemasons: Robert Mills (August 12, 1781 – March 3, 1855)

Robert Mills (August 12, 1781 – March 3, 1855), most famously known for designing the Washington Monument, is sometimes called the first native born American to become a professional architect, though Charles Bulfinch perhaps has a clearer claim to this honor. Mills studied in Charleston, South Carolina as a student of Irish-born architect James Hoban—who later designed the White House, which became the official home of US presidents. Both Hoban and Mills were Freemasons.
