Bodmer invited Wieland to Switzerland, but became disenchanted with his turn towards worldly pleasures. Leopold Mozart was a friend of Wieland’s, Goethe and Herder friends and professional colleagues in Weimar. Schopenhauer’s mother, worried about her son’s intended career as a philosopher, asked Wieland to talk to him about it (he supported the young man.) Hufeland was his doctor, Forster and Lavater correspondents. He showed Kleist a manuscript, while Gluck, a friend, advised him on effective libretto-writing, telling him to avoid secondary stories requiring extra sopranos.
