Hansen was posthumously awarded the 1941 Pulitzer Prize for History for The Atlantic Migration, 1607–1860: A History of the Continuing Settlement of the United States,[10] which was published in 1940 by Harvard University Press after historian Arthur M. Schlesinger, Sr. turned his rough draft into a polished manuscript.
