Fauré, both professionally and personally. In January his first violin sonata was performed at a Société Nationale concert with great success, marking a turning-point in his composing career at the age of 31. Nectoux counts the work as the composer's first great masterpiece. In March, Saint-Saëns retired from the Madeleine, succeeded as organist by Théodore Dubois, his choirmaster; Fauré was appointed to take over from Dubois. In July Fauré became engaged to Pauline Viardot's daughter Marianne, with whom he was deeply in love. To his great sorrow, she broke off the engagement in November 1877, for reasons that are not clear. To distract Fauré, Saint-Saëns took him to Weimar and introduced him to Franz Liszt. This visit gave Fauré a liking for foreign travel, which he indulged for the rest of his life. From 1878, he and Messager made trips abroad to see Wagner operas. They saw Das Rheingold and Die Walküre at the Cologne Opera; the complete Ring cycle at the Hofoper in Munich and at Her Majesty's Theatre in London; and Die Meistersinger in Munich and at Bayreuth, where they also saw Parsifal. They frequently performed as a party piece their joint composition, the irreverent Souvenirs de Bayreuth. This short, up-tempo piano work for four hands sends up themes from The Ring. Fauré admired Wagner and had a detailed knowledge of his music, but he was one of the few composers of his generation not to come under Wagner's musical influence. Middle years In 1883 Fauré married Marie Fremiet, the daughter of a leading sculptor, Emmanuel Fremiet. Nectoux comments that Marie was "without beauty, wit or a fortune ... narrow and cold", but records that "in spite of everything [Fauré] still felt a tenderness towards her". The marriage was affectionate, but Marie was, in Nectoux's phrase, "a stay-at-home", and she did not share her husband's wish to go out in the evenings, and became resentful of his frequent absences, his dislike of domestic life – "horreur du domicile" – and his love affairs, while she remained at home. Though Fauré valued Marie as a friend and confidante, writing to her often – sometimes daily – when away from home, she did not share his passionate nature, which found fulfilment elsewhere. Fauré and his wife had two sons. The first, born in 1883, Emmanuel Fauré-Fremiet (Marie insisted on combining her family name with Fauré's), became a biologist of international
