William Ewart Gladstone

William Ewart Gladstone (29 december 1809 – 19 may 1898) was a British Liberal politician. In a career lasting over sixty years, he served as Prime Minister four separate times (1868–74, 1880–85, February–July 1886 and 1892–94), more than any other person, and served as Chancellor of the Exchequer four times. Gladstone was also Britain's oldest Prime Minister; he resigned for the final time when was 84 years old. [..] A Gladstone bag, a light travelling bag, is named after him.

Conan Doyle and Gladstone

  • Memories and Adventures (1926) : Arthur Conan Doyle was what was called a Liberal-Unionist, that is, a man whose general position was Liberal, but who could not see his way to support Gladstone's Irish Policy.
  • Our African Winter (1928) : Arthur Conan Doyle made a counter-attack, pointing out that psychical research meant the study of the soul, that it was endorsed by Gladstone, Balfour, and many of the greatest minds, that the knowledge of the soul was the special job of the bishops and clergy, and yet that as far as I knew no bishop belonged to any Psychical Research Society the whole world over, save only one in Iceland.
