Merrill Daniel Peterson (31 March 1921 – 23 September 2009) was a history professor at the University of Virginia and the editor of the prestigious Library of America edition of the selected writings of Thomas Jefferson. Peterson wrote several books on Jefferson, including The Jefferson Image in the American Mind (Oxford University Press, 1960; reprinted with new foreword, University Press of Virginia, 1998), and Thomas Jefferson and the New Nation (Oxford University Press, 1970). Other works include Lincoln in American Memory (Oxford University Press, 1994), John Brown: The Legend Revisited (2002), and most recently Starving Armenians: America and the Armenian Genocide, 1915-1930 and After (Univ. of Virginia Press).
Merrill D. Peterson was born in Manhattan, Kansas, his father a Baptist minister. His parents divorced when he was in the third grade and his mother began running a boarding house.
After spending two years at Kansas State University, Peterson earned his B.A. at the University of Kansas and then took his Ph.D. in the history of American civilization at Harvard University.
After teaching at Brandeis and Princeton, Peterson was hired to teach at the University of Virginia, which remained his academic home for the rest of his life. He succeeded the great Jefferson biographer Dumas Malone there and ultimately became Thomas Jefferson Foundation Professor of History.
Peterson adapted his dissertation as his first book, The Jefferson Image in the American Mind (Oxford University Press, 1960), which won the 1961 Bancroft Prize for History. It is still hailed as a pioneering exploration of the history of American memory, which has become an increasingly important topic for historians. Peterson undertook the work to assess what history had made of Thomas Jefferson. At the end of a decade, he published a lengthy one-volume biography, Thomas Jefferson and the New Nation (Oxford University Press, 1970), which he considered his most important book. His 1994 Lincoln in American Memory, was written from a similar stance as his first book on Jefferson. It was a finalist for the 1995 Pulitzer Prize for biography.
