[1] He returned to Oxford and completed his history degree in 1920 before switching to geography (an interest in which had been prompted by his service in India).
[1] From 1922 to 1923 he was a lecturer at Bedford College, London before being appointed as a member of staff of the Oxford University School of Geography.
He was influential in the arrangements for the creation of the geography undergraduate degree at Oxford, which started in 1932, and was disappointed not to be appointed professor (the post going to Kenneth Mason).
His book, A History of Geographical Discovery and Exploration became the standard work in its field.
He was also a founder member (and later president) of the Institute of British Geographers, which broke away from the RGS in 1933.
Thereafter he increasingly spent time on his college duties, resigning his readership in 1947 (though he continued to lecture).
