and Moritz Between 1860 and 1863 Busch wrote more than one hundred articles for the Münchener Bilderbogen and Fliegende Blätter, but he felt his dependence on publisher Kaspar Braun had become constricting. Busch appointed Dresden publisher Heinrich Richter, the son of Saxon painter Ludwig Richter, as his new publisher – Richter's press up to that time was producing children's books and religious Christian devotional literature. Busch could choose themes, although Richter raised some concerns regarding four suggested illustrated tales that were proposed. However, some were published in the 1864 as Bilderpossen, proving a failure. Busch then offered Richter the manuscripts of Max and Moritz, waiving any fees. Richter rejected the manuscript as sales prospects seemed poor. Busch's former publisher, Braun, purchased the right to Max and Moritz for 1,000 gulden, corresponding to approximately double the annual wage of a craftsman. For Braun the manuscript was fortuitous. Initially the sales of Max and Moritz were slow, but sales figures improved after the 1868 second edition. Overall there were 56 editions and more than 430,000 copies sold up to Busch's death in 1908. Despite at first being ignored by critics, teachers in the 1870s described Max and Moritz as frivolous and an undesirable influence on the moral development of young people. Frankfurt Increasing economic success allowed Busch to visit Wiedensahl more frequently. Busch had decided to leave Munich, as only few relatives lived there and the artist association was temporarily disbanded. In June 1867 Busch met his brother Otto for the first time, in Frankfurt. Otto was working as a tutor to the family of a wealthy banker and industrialist, Kessler. Busch became friends with Kessler's wife, Johanna, a mother of seven and an influential art and music patron of Frankfurt. She regularly opened salons at her villa, frequented by artists, musicians, and philosophers. She believed Busch to be a great painter, a view supported by Anton Burger, a leading painter of the Kronberger Malerkolonie, the Kronberg-based group of painters. While his humorous drawings did not appeal to her, she supported his painting career. At first she established an apartment and studio for Busch in her villa, later providing him with an apartment nearby. Motivated by Kessler's support and admiration, and introduction to the cultural life of Frankfurt, the 'Frankfurter Years' were the most artistically productive for Busch. At this time he and Otto discovered the philosophical works of Arthur Schopenhauer. Busch
