Robert Frost was an American poet who achieved both critical and popular success during his lifetime. He published his first collection of poems, A Boy's Will, in 1913 at age 39, though he had been writing poetry for decades prior. Over the following decades, Frost published numerous collections that earned him widespread acclaim and four Pulitzer Prizes. His poems, often set in rural New England, explored themes of nature, isolation, and community through precise language and form. Though he worked within traditional forms, Frost's innovative use of language and variation helped shape American poetry in the early 20th century.
