Pauline Joran (1870 " 13 August 1954) was an American-born opera singer and violinist. She was the wife of William Ernest Bush, the first and last Baron de Bush, and mother of Paulise de Bush, the "Baby Baroness". She is remembered for creating the role of Saida in Arthur Sullivan's 1898 Savoy opera The Beauty Stone.
After a touring career as a child violinist, playing together with her pianist sisters in the U.S. and abroad in the 1880s, Joran began an opera career in England, which lasted through the 1890s. With her marriage to Baron de Bush in 1899, she retired from the stage. He was killed in an accident in 1903, and Joran lived quietly for some years, returning to society by 1910 as a hostess and patroness of music.
