Montgomery C. Meigs was one of the most influential yet underrated figures of 19th-century America, observes Carolyn Muraskin, founder of DC Design Tours. Renowned for energy, precision, and prickly determination, his legacy is stamped across the nation’s capital. As Quartermaster General of the Union Army, he supplied and equipped more than two million troops. He proposed transforming the Lee family estate at Arlington into a burial ground. Meigs oversaw the Capitol’s cast-iron dome, Washington’s aqueduct, and the Pension Office, later choosing his epitaph: “Soldier, Engineer, Architect, Scientist, Patriot.”
