After Karl May's death, E.A. Schmid obtained the rights to all of his works. He believed in the myth that Karl May's novels had been thoroughly rewritten without the author's consent and made sure that the original versions were no longer published. He then created what he regarded as "improved" versions of all of Karl May's works. Especially the disputed novels, originally published by Münchmeyer, were rewritten rather dramatically; large parts of the plot were removed and new solutions to certain mysteries were invented; characters from Karl May's more popular novels were added; etc. Generations of readers have known Karl May only through Schmid's adaptations. After Karl May's works had entered the public domain, a few editions presenting the original texts have been published, but the vast majority of all books sold in Germany under the name of Karl May still contains the adaptations by Schmid et al. I have read that Karl May was the most frequently translated German author of all times, but unfortunately this does not apply to the English language. Though even the Encyclopaedia Britannica describes him as "one of the world's all-time fiction best-sellers", he is virtually unknown by most English speaking readers. The earliest English translation of one of his works came in 1886, probably in the form of a weekly series of booklets under the title "Rosita" (a translation of "Das Waldröschen", the first one of those disputed novels Karl May had written for H.G. Münchmeyer under a pseudonym). I suppose, these booklets were just as quickly discarded and forgotten as they were printed. In 1898, two books entitled "Winnetou, the Apache knight" and "The Treasure of Nugget Mountain" were published, containing a severely abridged and altered translation by Marion Ames Taggart of Karl May's most famous novel "Winnetou". Among other things, the main character is changed from a German, implicitly a Protestant, into an American, whom the translator has named Jack Hildreth and who keeps on emphasising that he was a Catholic. In one place, the translator has even added a line in which the hero is made to point out that the religion of the murderer Rattler was not his own, but that of a non-Catholic, when Winnetou suggests to him that he had the same religion as the murderer. In the original book, the hero simply answers "Yes" and then goes on to explain, as he also does in the translation, that the murderer did not keep the commandments. These liberties of the translation are particular serious since Karl May often had to defend himself against allegations of promoting Catholicism, though being a Protestant, just because he published many of his stories in a Catholic magazine. In 1900, the series of translations by M.A. Taggart was continued with "Jack Hildreth on the Nile", based on Karl May's "Der Mahdi" a.k.a. "Im Lande des Mahdi".
