Q: Passage: He was a founder of the St. Louis Art Museum and the State Historical Society of Missouri, president of the St. Louis Public Library, and a director of the St. Louis World's Fair (Louisiana Purchase Exposition) of 1904, in which he was host of the Universal Congress of Jurists and Lawyers. He was a bibliophile and he collected rare first editions of Charles Dickens, Robert Burns and others, and artworks of Aubrey Beardsley, George Cruikshank and Thomas Rowlandson. He and industrialist William K. Bixby started the Burns Society; he was twice president of the University Club of St. Louis.

His published works included: John Marshall (1901); The Lawyer in American History (1906); Abraham Lincoln (1908); Conservatism in Legal Procedure (1909); Prohibition (1910); and The Law and the Newspaper (1917).
