Dorothy Kirsten (July 6, 1910, Montclair, New Jersey — November 18, 1992, Los Angeles, California) was an American operatic soprano.
Kirsten's mother was an organist and music teacher, her grandfather was a conductor, and her great-aunt, Catherine Hayes, was also an opera singer. She left high school at age 16 and worked for the Singer Corporation sewing machine company and for New Jersey Bell, studying voice in her spare time. Her teacher, Louis Darnay, eventually employed her as a secretary and maid.
By the late 1930s she had an ongoing professional career as a radio singer on WINS, a member of the Kate Smith Chorus, and as a vocalist for pop orchestras. She mentored under Grace Moore from 1938, who had her study in Rome with Astolfo Pescia. Her time in Europe was cut short by the outbreak of World War II, and she returned in 1939, debuting at the New York World's Fair. Roles followed at the Chicago Grand Opera Company (Manon, 1940), San Carlo Opera Company (1942), New York City Opera (1943), San Francisco Opera (1945), and New York Philharmonic (1945). Her radio program "Keepsakes" ran for a year in 1943-44.
Kirsten joined the roster of principle sopranos at the Philadelphia La
