After graduating from Oxford University, Grigson took a job at the London office of the "Yorkshire Post", from where he moved on to become literary editor of the "Morning Post". He first came to prominence in the 1930s as a poet, then as editor from 1933 to 1939 of the influential poetry magazine "New Verse". Among important works by many influential poets — notably Louis MacNeice, Stephen Spender, Dylan Thomas, W. H. Auden, Paul Éluard and Grigson himself — "New Verse" featured concrete poetry by the sculptor Alberto Giacometti (translated by David Gascoyne) and folk poetry from tribal villages of the Jagdalpür Tahsil district of Bastar State, Chhattisgarh, transcribed from the Halbi language by Grigson's brother Wilfrid Grigson. During this period, Grigson published some of his own poetry under the pseudonym Martin Boldero. An anthology of poems that appeared in the first 30 issues of "New Verse" was published in hardback by Faber & Faber in 1939, and re-published in 1942; the second edition states that the first "came out on the day war was declared".
