English poet and translator, prominent in the Imagist movement (expression of precise images in free verse), whose best poems reflect the disciplined economy of that school.

The son of a commercial traveler, Flint left school at the age of 13 and worked at a variety of jobs. At the age of 17 his reading of a volume by the 19th-century Romantic poet John Keats fired his enthusiasm for poetry. Two years later he became a civil-service typist and enrolled in a workingman's night school. He learned French and Latin (eventually he mastered 10 languages) and after World War I rose to become a high official in the Ministry of Labour.

Flint's first volume of poetry, In the Net of the Stars (1909), was a collection of love lyrics, clearly showing the influence of Keats and his contemporary Percy Bysshe Shelley. The same year, he and a group of young poets, all dissatisfied with the state of English poetry, began working to overthrow conventional versification and to replace strict metre with unrhymed cadence (a term he appropriated). His friendship with the English poet T.E. Hulme (Hulme, T.E.) and the American poet Ezra Pound (Pound, Ezra) helped him to develop further his own distinctive poetic style. Cadences (1915) and Otherworld (1925) established him as a leading member of the Imagists.

After the death of his wife in 1920, Flint suddenly stopped writing. He did, however, continue to produce translations, mostly of French works.
