Harry Dickson is a fictional pulp detective, born in America, educated in London, and was called The American Sherlock Holmes. He has appeared in almost 200 pulp magazines published in Germany, the Netherlands, Belgium and France.
The original pulp dime-novel series that later became Harry Dickson began in Germany in January 1907 under the title of Detective 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 dem 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.
Sixteen issues of the original German series were adapted into French starting in October 1907 by publisher Fernand Laven for the magazine La Nouvelle Populaire under the title Les Dossiers Secrets de Sherlock Holmes (Sherlock Holmes' Secret Files) for No. 1, immediately changed to Les Dossiers Secrets du Roi des Détectives (The Secret Files of the King of Detectives) with issue No. 2.
