Robert Frost (1874–1963) was born in San Francisco, California, but is most identified with rural New England, the landscape of his greatest poetry. His debut collection A Boy's Will (1913) and its successor North of Boston (1914) were published in England to immediate critical acclaim. Returning to America, he became the most celebrated American poet of his time. He won the Pulitzer Prize for Poetry four times, for New Hampshire (1923), Collected Poems (1930), A Further Range (1936), and A Witness Tree (1942). He recited The Gift Outright at John F. Kennedy's inauguration in 1961. His apparently simple verse conceals formal mastery and a deeply ambivalent vision of the natural world and human isolation.
