Prufrock and Other Observations, T.S. Eliot's debut collection, was published in June 1917 by the Egoist Press in London, at the height of World War I. The volume collected Prufrock alongside several other poems that deployed irony, learned allusion, and fractured narrative to capture the alienation of modern urban life. It established Eliot as a major new voice in English literature while the war continued to reshape the world around him.

T.S. Eliot's publication of 'Prufrock' in 1917 advanced modernist poetry, contrasting sharply with traditional war verse. His innovative use of stream-of-consciousness and fragmented structure influenced countless poets, redefining the boundaries of poetic form.
