In February 1892 she gained her first real success at the Union Square Theatre in New York in the role of the Queen in "The Black Masque". This performance made her famous, and from the opening night her services were in great demand. A few weeks later she became leading woman in A.M. Palmer's stock company, then considered the leading one in America. With it she played Jeanne in the "Broken Seal"; Letty Fletcher in "Saints and Sinners"; and Lady Windermere in "Lady Windermere's Fan" – her Broadway debut, on February 5, 1893; but her greatest triumph was in "Mercedes", a short play by Thomas Bailey Aldrich. She made such an impression that the author presented her with the full rights to the play.
