Nancy Isobel McIntosh (25 October 1866 – February 20, 1954)[1] was an American-born singer and actress who performed mostly on the London stage. Her father was a member of the South Fork Fishing and Hunting Club, which had been blamed in connection with the 1889 Johnstown Flood that resulted in the loss of over 2,200 lives in Johnstown, Pennsylvania.
McIntosh is perhaps best known for creating the role of Princess Zara in Gilbert and Sullivan's Utopia, Limited in 1893. She obtained this role after beginning a concert singing career in America in 1887, moving to London in 1890 and continuing her concert career in Britain. She became one of the last of W. S. Gilbert's actress protégées and continued her acting and singing career in Britain and America for several years. After McIntosh retired from the stage, she lived with Gilbert and his wife until Lady Gilbert's death in 1936 and eventually inherited Gilbert's estate, helping to preserve his legacy by selling his papers to the British Museum and leaving the remainder of the Gilbert estate to the Royal General Theatrical Fund.
