Elected Master of Corpus in 1927[4] he was Vice Chancellor of the University of Cambridge from 1931 to 1933 and then chaired the consultative committee of the Board of Education (known in retrospect as the Spens Report[5]) which recommended the tri-partite split of secondary schooling into grammar, technical and modern varieties.[6]
During the Second World War he was Regional Commissioner for Civil Defence for the Eastern Region, which prompted and exacerbated rumours that the cellars of Corpus extend across (and indeed further than) the entire college campus and that the college was to be used as the centre of operations for East Anglia in the event of a German occupation.[7][8] Spens wished to maintain the high moral ground in fighting the Nazis. He opposed the use of guerrilla warfare behind enemy lines to oppose any Nazi invasion as being contrary to international convention. He objected first to the plans of SIS in June 1940 and then to the operation of the Auxiliary Units - threatening to have them arrested![9]
Spens retired in 1952.
