Sixty years after the death of his father, William Arden Maury eulogized Maury by associating him with three main efforts. First, he claims that Maury and the philanthropist William Wilson Corcoran convinced Congress to appropriate funds for the Government Hospital for the Insane, now known as St. Elizabeths. Second, he notes that Maury was mayor when Congress funded a study under the supervision of Montgomery C. Meigs to improve the public water supply by means of the Washington Aqueduct. Third, he recounts that Maury provided payments to sculptor Clark Mills to complete the statue of Andrew Jackson on horseback that stands in Lafayette Square, across the street from the White House. Mills later repaid Maury from a commission for an equestrian statue of George Washington.
