Goethe became friendlier: while the two of them were visiting Emmendingen, Goethe introduced Lenz to his sister Cornelia and her husband Johann Georg Schlosser. In April 1776 Lenz followed Goethe to the court of Weimar, where he was at first amicably received. But in early December, on Goethe's instigation, he was expelled. The exact circumstances are not recorded; Goethe, who broke off all personal contact with him after this, refers only vaguely in his diary to "Lenz's asininity" ("Lenzens Eseley"). Lenz then returned to Emmendingen, where the Schlossers took him in. From there he made a number of journeys into Alsace and Switzerland, including one to Lavater in Zürich in May 1777. The news of Cornelia Schlosser's death, which reached him there in June of that year, had a powerful effect on him. He returned to Emmendingen, and then went back to Lavater. In November, while staying in Winterthur with Christoph Kaufmann, he suffered an attack of paranoid schizophrenia. In January 1778 Kaufmann sent Lenz to the philanthropist, social reformer and clergyman Johann Friedrich Oberlin in Waldersbach in Alsace, where he stayed from 20 January to 8 February. Despite the care of Oberlin and his wife, Lenz's mental condition grew worse. He returned to Schlosser at Emmendingen, where he was lodged with a shoemaker and then a forester. His younger brother Karl fetched him in June 1779 from Hertingen, where he was under treatment by a doctor, and brought him to Riga, where their father by this time had risen to the position of General Superintendent. Lenz was unable to establish himself professionally in Riga. An attempt to make him director of the cathedral school came to nothing, as Herder refused to give him a reference. Nor did he have any greater success in St. Petersburg, where he lived from February to September 1780. He then took a position as a private tutor on an estate near Dorpat, then, after another stay in St. Petersburg, he went to Moscow in September 1781, where initially he stayed with the historian Friedrich Müller and learned Russian. He worked as a private tutor, mixed in the circles of Russian Freemasons and authors, and helped produce a number of reformist schemes. He also translated books on Russian history into German. His mental condition however was steadily deteriorating all the while, and at last he became entirely dependent on the goodwill of Russian patrons for
