business and from then on worked only as a publisher and bookseller in the publishing house A. Kröner Verlagsbuchhandlung. His first author was Melchior Meyr, who was followed by the literary figures he met in Munich and whose works he published in the Munich Poets' Book in 1862 and 1863. Wilhelm Hertz, Paul Heyse and above all Hermann Kurz subsequently had their books published by him. In addition, through the purchase of two small publishing houses - Becherscher Verlag in 1864, Krabbescher Verlag in 1870 (according to other sources in 1873) - he also attracted Hans Hopfen, Ernst Eckstein, Wolfgang Menzel and Robert von Hornstein as authors. Carl Kröner, his brother, joined the publishing house as a partner in 1867, while Paul Kröner had already taken over the printing house in 1864. In 1877, the two businesses were brought back together under one roof with the name Gebrüder Kröner, in which Kröner's second brother Karl was also involved, although he left the business again as early as 1883. In addition to the books named, Kröner also published the conservative Schwäbische Volkszeitung. In 1884, Adolf Kröner expanded his business by taking over the publishing house of the late Ernst Keil, who published the journal Die Gartenlaube, and took over the editing of the journal until it was discontinued in 1903. In 1886, his son Alfred also entered the management of the journal and took over its management. Kröner was the first publisher of the journal in Germany. On January 1, 1889, he also took over the J. G. Cotta'sche Buchhandlung in Stuttgart, founded by Johann Georg Cotta, which he had already taken on lease since 1879, and continued to run it as J.G. Cotta'sche Buchhandlung Nachfolger. He had already purchased Cotta'sche Druckerei in 1886, and together with Carl von Cotta he had been publishing Bibliothek der Weltliteratur since 1882. The Allgemeine Zeitung, which he had acquired together with Cotta's publishing house, went to a private limited company (GmbH) in Munich in 1895. In 1890 he founded Union Deutsche Verlagsgesellschaft by combining the publishing houses of Herrmann Schönlein (acquired as early as 1888), Wilhelm Spemann (who was a partner in the publishing house from 1891 to 1897) and one of his own, and took over the management and later the position of chairman of the supervisory board until 1904, when he handed over the management to Heinrich Beck. In 1897, Kröner acquired
