In 1849 a new epoch was opened in the history of this remarkable man. The grand duke of Weimar invited him to assume the direction of his musical establishment, including the opera. The salary was absurdly small--$800 or $1,000 a year. This, however, cut no figure in Liszt's mind, for he had always been singularly open-handed, yet at same time prudent. From his successful concert tours he had put by funds, 20,000 francs for his aged mother, and 20,000 francs for each of the three children he had by the Countess D'Agoult (known in literature as Daniel Stern), and he considered that the position would afford him an opportunity of developing his own talent for composition, and at the same time of affording a hearing for important new works, which, on account of their novelty and originality, were impossible of performance in the theaters of large cities. The repertory of the Weimar opera, from this time on, was most extraordinary. Here were produced for the first time Wagner's "Flying Dutchman," "_Tannhaeuser_," and "_Lohengrin_," "_Benvenuto Cellini_," of Berlioz, Schumann's "_Genoveva_" and "_Mannfred_," and Schubert's "Alfonso and Estrella." Here were produced, also, the best of the operas of previous generations. Every master work of this sort Liszt revised with the greatest care, giving endless patience to every detail, and supplementing the resources of the theater, when insufficient, by "guests" from the great operas in the capital. Thus the musical establishment at Weimar became a sort of Mecca, to which all the musicians of the world gathered, especially the young and energetic in the pursuit of knowledge, and creative artists seeking a hearing or fresh inspiration. From an artistic standpoint, nothing more beautiful than the life of Liszt at Weimar could be desired. Besides these operatic performances and his symphony concerts, he gathered about him a succession of young virtuosi pianists. These had lessons, more or less formally, some of them for many years. Liszt never received money for lessons, and took no pupils but those whom he regarded as promising, or who were personally attractive to himself. About 1850 the American, Dr. William Mason, was there, and for two years following. The class at this time contained the well known names of Rubinstein, Carl Klindworth, Pruckner, Tausig, Joachim Raff, and Hans von Buelow. From this time on there is scarcely a concert pianist in the world who did not spend a few months or longer with Liszt at Weimar. Nor did his influence stop here. He produced a constant succession of important works, and conducted concerts and festivals in Hungary, and in different parts of Germany and France. Everywhere his inspiring presence and his keen insight were prized above all ordinary resources.
