In Munich, he came under the influence of the German Romantic movement, and this is reflected in his poetry. Among the figures, he knew personally were the poet Heinrich Heine and the philosopher Friedrich Schelling. In 1826, he married the Bavarian widow of a Russian diplomat Eleonore Peterson, née Countess von Bothmer. She became the mother of his daughter Anna Tiuttjev. Following her death in 1838, Tyutchev married another aristocratic young German widow, Baroness Ernestine von Dörnberg, née von Pfeffel, who had become his mistress and had a child by him while Eleonore was still alive. Neither of his wives understood Russian to begin with (Ernestine made efforts to learn the language only much later). That is hardly surprising since Tyutchev spoke French better than Russian and nearly all his private correspondence was in the former language.
