'', c. 1889 In December 1883, also at Haverley's, she scored a hit in the English version of the
Carl Millöcker operetta
Der Bettelstudent (
The Beggar Student). This led to
Rudolph Aronson choosing her, early in 1884, to sing at New York's
Casino Theatre. In the spring of 1884
Charles Wyndham signed Jansen to create, at London's
Criterion Theatre, the lead role, Mrs. Coney, in
Featherbrain, from the French play
La Téte de Linotte by
Théodore Barrière and
Edmond Gondinet.
Featherbrain had a successful run of eight months. Jansen played the title role in a four-month run at the
Boston Museum of the comic opera
Fantine, by
Firmin Bernicat and
André Messager that was adapted by B. E. Woolf and R. M. Field (manager of the Boston Museum), with additional music supplied by Woolf. She next sang the role of Phyllis in
Iolanthe. In May 1885, with the
McCaull Comic Opera Company, Jansen played Rosetta in
Sydney Rosenfeld's adaptation of the Millöcker comic opera
Der schwarze Husar (
The Black Hussars). A year later at the Casino Theatre, she played Javotte in
Erminie, the hit comic opera composed by
Edward Jakobowski. When she joined the cast of
Erminie, Aronson added a song for her,
Sunday after Three, My Sweetheart Comes to Me, that he adapted from an old German tune. In May 1888, again at the Casino, Jansen created for the American stage the title role in
Nadjy, adapted by Alfred Murray from the
Francis Chassaigne operetta,
Les noces improvises. Jansen performed the role after only five days rehearsal following
Sadie Martinot's last minute departure over a creative dispute.
Nadjy went on to have a run of 256 performances. In May 1889 Jansen played Tourouloupi, the wife of Cadi, in
The Oolah, the first of three successful comic operas she performed in with
Francis Wilson's Opera Company at the old
Broadway Theatre on 41st Street, New York.
The Oolah, by Sydney Aronson and
Charles Lecocq, was memorable in part for Jansen's rendition of the song, "Be Good", which some considered too suggestive. She was Tessa in Wilson's 1890 Philadelphia production of
The Gondoliers. In 1893 Jansen began a several-years-long tour at Boston's
Howard Athenaeum as Trixie Hazelmere the Queen of the Vaudevilles in ''Delmonico's at Six
, a comic play written specifically for her by Glen MacDonough. Over the season of 1897–98 she played Pearl Dodo in a musical farce by Frank Tannehill, Jr., entitled The Nancy Hanks'', a success in which she and Tannehill "succeeded in bringing down the house on several occasions." ==Later years==
