Over-extension ultimately proved Newhouse's financial downfall, as the money from his mines could not finance his elaborate projects and World War I made it almost impossible to obtain loans from eastern U.S. and European sources. In 1914 Samuel and Ida separated. The South Temple mansion was sold, and between 1915 and 1919 Samuel resided at the *Newhouse Hotel. He then sold his interest in the hotel and left for France, where he lived with his sister at the chateau outside Paris he had given to her. He died there on 22 September 1930 at the age of seventy-six.
