    (19) Not only was he a poet but a biographer also. His poems are in rugged Middle Western speech mixed with lyric passages. They were written in free, unrhymed verses and have often been compared to the poems of Walt Whitman.
    Sandburg’s book "Abraham Lincoln" is often considered the greatest biography of modern time. He won the Pulitzer Prize in 1940 for "The Prairie Years" and "The War Years". His first novel was "Remembrance Rock" in 1948. (20) Again in 1951 he received the Pulitzer Prize for his Collected Poems.
