in 1815. For the second edition, two volumes containing the KHM texts were issued in 1819 and the appendix was removed and published separately in the third volume in 1822, totaling 170 tales. The third edition appeared in 1837, the fourth edition in 1840, the fifth edition in 1843, the sixth edition in 1850, and the seventh edition in 1857. Stories were added, and also removed, from one edition to the next, until the seventh held 210 tales. Some later editions were extensively illustrated, first by Philipp Grot Johann and, after his death in 1892, by German illustrator Robert Leinweber. The first volumes were much criticized because, although they were called "Children's Tales", they were not regarded as suitable for children, both for the scholarly information included and the subject matter. Many changes through the editions – such as turning the wicked mother of the first edition in Snow White and Hansel and Gretel (shown in original Grimm stories as Hänsel and Grethel) to a stepmother, were probably made with an eye to such suitability. Jack Zipes believes that the Grimms made the change in later editions because they "held motherhood sacred". They removed sexual references—such as Rapunzel's innocently asking why her dress was getting tight around her belly, and thus naively revealing to the witch Dame Gothel her pregnancy and the prince's visits—but, in many respects, violence, particularly when punishing villains, become more prevalent. Popularity The brothers' initial intention of their first book, Children’s and Household Tales, was to establish a name for themselves in the world. After publishing the first KHM in 1812, they published a second, augmented and re-edited, volume in 1815. In 1816 Volume I of the German Legends () was published, followed in 1818, Volume II. However, the book that established their international success was not any of their tales, but Jacob's German Grammar in 1819. In 1825, the Brothers published their Kleine Ausgabe or "small edition", a selection of 50 tales designed for child readers. This children's version went through ten editions between 1825 and 1858. In 1830, Jacob became a professor at University of Göttingen and in 1835, Wilhelm also became a professor. During these years Jacob wrote a third volume of German Grammar and Wilhelm prepared the third revision of the Children’s and Household Tales. In 1837, King Ernst August II revoked the constitution of 1833 and was attempting to restore absolutism
