G. K. Chettur, arrived to study at New College, Oxford, in October 1918, just before the Armistice. He had been educated at Madras Christian College and his father, P. K. Krishna Menon, had been a Government Servant. Funding for his studies at Oxford were supplied by Sir C. Senkaramhair from Simla. He graduated with a Third in history in 1921.

Chettur was a member of the Lotus Club and the Oxford Majlis (he was President in Hilary Term, 1920) and was able to meet Rabindranath Tagore and W. B. Yeats through these societies. Yeats spoke to the Majlis in November 1919 on the poet Manmohan Ghose and Chettur obtained a photo of Yeats in his New College room. Chettur published his first anthology of poems in 1922 with a dedication to Yeats, and was inspired by Yeats to publish his memories of his students days. During his time in Oxford, Chettur met a number of other poets based in Oxford and Sarojini Naidu, who made frequent visits to Oxford. His publications were reviewed in the British Press.

During his student days, Chettur saw the play 'Tilly of Bloomsbury' by Ian Hay, where an Indian student was depicted as a humiliating figure. Chettur was so angry and offended by this portrayal that he wrote a letter to the Vice-Chancellor in complaint. Chettur was principal of the Government College in Mangalore from 1922 and continued to write and publish poetry in India.
