The first biography on Busch , Über Wilhelm Busch und seine Bedeutung ( About Wilhelm Busch and His Importance ) , was released in 1886 . The publisher Eduard Daelen , also an artist and writer , echoed Busch 's anti @-@ Catholic bias , putting him on equal footing with Leonardo da Vinci , Peter Paul Rubens and Gottfried Wilhelm Leibniz , and uncritically quoting correspondences . Even Busch and his friends was embarrassed . Literary scholar Friedrich Theodor Vischer attacked Daelen 's biography and called him the " envious eunuch of the desiccated Philistine " . After reading this biography Johannes Proelß posted an essay in the Frankfurter Zeitung , which contained many biographical falsehoods — as a response to this , Busch wrote two articles in the same newspaper . Published in October and December 1886 , the autobiographical essay Regarding Myself ( Was Mich Betrifft ) include basic facts , and some description of his troubles ; analysts see within the essay a deep identity crisis . Busch revised his autobiography over the following years . The last such essay was published under the title From Me About Me ( Von mir über mich ) , which include fewer biographical details and less reflection on bitterness and amusement than Regarding Myself .
