Cameron was born Susan Hegeman in
Troy, New York in 1868. She was the daughter of William H. and Esther Byram Hegeman. She married Mansfield on September 15, 1892. She continued to perform with him in their touring company. While traveling to a show in
Milwaukee, Wisconsin in February 1895, Cameron and a maid were injured when an out of control passenger coach crashed into their private rail car. The evening's performance was cancelled, but both women escaped with only minor injuries. Their only child, George Gibbs Mansfield, was born on August 8, 1898. In 1920, Cameron engaged in relief work for victims of the
Armenian genocide in
Urfa, Turkey, when the American humanitarian compounds housing Armenian orphans came under siege. There she came under Turkish fire. Soon afterwards, she did relief work with the refugees in Jerusalem. She recited Shakespeare to the suffering and hungry refugees. She subsequently participated in relief efforts in Syria and Czechoslovakia, supported
women's suffrage and was active in the
League of Women Voters. Cameron donated her late husband's costumes to the
Smithsonian Institution and the
Carnegie Institute of Technology. She donated to Episcopal churches, including the
Church of the Transfiguration in New York, in his honor. In 1925 she organized a theater company, the Richard Mansfield Players, and in 1932 she staged a revival of
Arms and the Man in his memory. She lived in their home in
New London, Connecticut until her own death due to
coronary thrombosis on July 12, 1940. ==References==
