Final answer:
T. S. Eliot was greatly influenced by Ezra Pound after meeting him. Pound's editorial suggestions on Eliot's 'The Waste Land' and his imagist principles had a lasting impact on modernist literature.
Step-by-step explanation:
The poet who met Ezra Pound and was greatly affected in their writing thereafter was T. S. Eliot. Pound's influence on Eliot was profound, with Pound offering significant editorial input on Eliot's seminal poem, 'The Waste Land'. As a modernist poet and editor, Pound was central to shaping the literary movement of his time, advocating for the Imagist and Vorticist movements and the notion of making poetry new.
His advice to cut superfluous words has resonated with many writers, including William Carlos Williams, who shared the sentiment in his approach to writing.
Pound’s imagist principles are exemplified in his work 'In a Station of the Metro', which captures a momentary experience with clarity and brevity, much like a Japanese haiku. His influence extended beyond Eliot to other members of the 'Lost Generation' and can be seen in the works of writers such as Hemingway and Joyce, who also sought to innovate literary form and express their disenchantment with society through their art.
