Cass Gilbert Cass Gilbert Cass Gilbert (November 24, 1859 – May 17, 1934) was a prominent American architect. An early proponent of skyscrapers in works like the Woolworth Building, Gilbert was also responsible for the Saint Louis Art Museum and Public Library; the Minnesota, Arkansas and West Virginia State Capitols; and the United States Supreme Court building. His public buildings in the Beaux Arts style reflect the optimistic American sense that the nation was heir to Greek democracy, Roman law and Renaissance humanism. Gilbert's achievements were recognized in his lifetime; he served as president of the American Institute of Architects in 1908–09.
