Venn was educated at Eastbourne College and Trinity College, Cambridge. He took his honours in the History Tripos in 1904–1905. During the First World War he was a lieutenant for three years in the Cambridgeshire Regiment and then served as a statistician in the Food Production Department. He served on the Scientific Council of the International Institute of Agriculture and many other Departmental committees of the Ministry of Agriculture. Venn was elected a Fellow in 1927 and had been a Junior Fellow and Bursar at Queens' before being elected president on the death of Thomas Cecil Fitzpatrick in 1932. At the time he was the youngest Head of a college in Cambridge. He was also the Gilbey Lecturer in Agriculture.

The Guyanese writer Arthur Seymour was visiting Venn in the Queens' College Presidential Lodge when Venn showed Seymour the proofs of Alumni Cantabrigienses. Thirty years later the memory of seeing these proofs inspired Seymour to propose the creation of a Guyana National Encyclopedia modelled on the Australian National Encyclopedia. Although Seymour failed to gain financial support for the project, Venn's example did inspire Seymour to publish two volumes of the Dictionary of Guyanese Biography which were published in 1984 and 1986.
