Robert Mills (August 12, 1781 – March 3, 1855) was a South Carolina architect and cartographer known for designing both the first Washington Monument, located in Baltimore, Maryland, as well as the better known monument to the first president in the nation's capital, Washington, DC. He is sometimes said to be the first native-born American to be professionally trained as an architect. Charles Bulfinch of Boston perhaps has a clearer claim to this honor. Mills studied in Charleston, South Carolina, as a student in the lower school at the College of Charleston and of Irish architect James Hoban, and later worked with him on his commission for the White House. This became the official home of US presidents. Both Hoban and Mills were Freemasons. Mills also studied and worked with Benjamin Henry Latrobe of Philadelphia. He designed numerous buildings in Philadelphia, Baltimore, and South Carolina, where he was appointed as superintendent of public buildings. His Washington Monument in Washington, DC was not completed until 1885, 30 years after his death. Source: Wikipedia (en)
