The original pulp dime-novel series that later became "Harry Dickson" began in Germany in January 1907 under the title of "Detektiv Sherlock Holmes und seine weltberühmten Abenteuer" (Sherlock Holmes' Most Famous Cases), published by "Verlagshaus für Volksliteratur und Kunst", and comprised 230 issues in total, published until June 1911. The name "Sherlock Holmes" was actually used for the first 10 issues. After some concern about the rights of Sir Arthur Conan Doyle, the series was retitled "Aus den Geheimakten des Weltdetektivs" (The Secret Files of the King of Detectives) with No. 11, even though the main character was still called "Sherlock Holmes" inside. Holmes' "Doctor Watson" sidekick, however, was a younger man named "Harry Taxon".
