Architect Robert Mills, a U.S. government architect and engineer celebrated for his neoclassical structures, submitted the winning design for the Washington Monument in a competition held in 1836. He designed the world's tallest obelisk, which, at 555 feet in height, is also the District of Columbia’s most prominent structure or, as Dan Brown writes (p. 13), “the city’s centerpiece.” Mills, a Mason, did not live to see the Monument’s completion in 1888. He died in 1855.
