Which poet won three Pulitzer Prizes, two for poetry?

Carl Sandburg is the only poet in this list who won three Pulitzer Prizes, with two of those awarded specifically for his poetry. He received the Pulitzer Prize for Poetry in 1919 for his work "Cornhuskers" and again in 1951 for "Complete Poems." Additionally, Sandburg was awarded the Pulitzer Prize for History in 1940 for his biography of Abraham Lincoln, further exemplifying his diverse talents and contributions to American literature.

The other poets mentioned did not match Sandburg's achievements in terms of Pulitzer Prizes. Ezra Pound, influential for his modernist poetry, did not win a Pulitzer. William Carlos Williams, known for his innovative use of language and imagery, received only one Pulitzer for poetry. Maya Angelou, famous for her powerful autobiographical writings and poetry that addresses themes of identity and racism, did not win multiple Pulitzer Prizes for her poetry, despite her significant literary impact. Sandburg's unique combination of multiple Pulitzer wins in different categories makes him the correct answer to this question.
