In 1949, Dickens was appointed professor of history at the
University of Hull, later becoming deputy principal and dean of the Faculty of Arts, 1950–53, and
pro-vice-chancellor, 1959–62. He took up the post of professor of history at
King's College London in 1962, where he remained until becoming director of the
Institute of Historical Research (IHR) and professor of history in the
University of London, 1967–77. Dickens was also active in other bodies, including being president of the
Ecclesiastical History Society, 1966–68; a member of the Advisory Council on Public Records, 1968–76; an advisor to the Council on the Export of Works of Art, 1968–76; secretary, chairman and general secretary of the British National Committee of Historical Sciences, 1967–79; foreign secretary of the
British Academy, 1969–79; and vice-president of the
British Record Society, 1978–80. Dickens enjoyed "a deep love affair with Germany", was a moving force in the establishment of the German Historical Institute in London and was decorated by the German government. He died in London at the age of 91. His book on the
English Reformation was, for many years the standard text on the subject, relying as it did on detailed examination of parish records. He was elected a fellow of the
British Academy in 1966. ==Death and legacy==
