After the war, despite his background in
classics, Rishbeth was attracted to geography "because of the opportunity it afforded ... to construct a synthesis of the different fields of knowledge concerned with man/environment relationships". Some of his early research was inspired by his military service. In 1919, Rishbeth presented research on the
Dodecanese islands, where he had served in the war, to the British Association for the Advancement of Science. In March 1920 he was invited by the
Royal Geographical Society to respond to a lecture on the Dodecanese by
John Myres, together with
Eleftherios Venizelos, then Prime Minister of Greece. This interest continued; Rishbeth's last paper, albeit unpublished, was on the "corn supply of ancient Greece". and Central Australia. In 1926, he led a geographic survey of the
Hampshire district, and later contributed a study of land utilization in Southampton. In 1923 he published a new theory on the structure of the earth. In 1933, Rishbeth was a founding member of the
Institute of British Geographers. He was involved in the joint committee to form an "Association of University Geographers". Rishbeth retired due to ill health in 1938. His correspondence and papers are held at Oxford University's
Bodleian Library. ==Family==
