John Atkinson Hobson was one of the most prolific and sophisticated writers on social and economic affairs that British society encountered in the fifty or so years which preceded the outbreak of the Second World War. Only one aspect of his work-his attitudes towards the Jews-is investigated here and attention is restricted to the years between 1880 and 1914, the period immediately preceding the outbreak of the war which was to have profound effects upon the whole of European economic, social, political and intellectual life. In connection with such a study some reference is necessary to his work on Jewish immigration in the 1880s and 1890s, his comments on the role of rich Jews in British society during the same years, as well as some consideration of his writings on Jewish involvement in the Boer War. These issues are taken in turn before moving on to wider matters.
