 Success outside of Paris was elusive for Sanderson; she appeared at Covent Garden and the Metropolitan Opera (debut in title role of "Manon" on January 16, 1895, the last performance as Juliette in "Roméo et Juliette" on December 31, 1901) to lackluster reviews.In 1897 she married a Cuban millionaire and sugar heir Antonio E. Terry (d. 1899), after which she temporarily halted her operatic activity, making an unsuccessful comeback two years later.Her last years were marred by depression, alcoholism and illness and she died in Paris of a malignant influenza (pneumonia), at the age of thirty-eight.
