Perry Gilbert Eddy Miller (February 25, 1905 – December 9, 1963) was an American intellectual historian and Harvard University professor. He was an authority on American Puritanism, and a co-founder of the field of American Studies. Alfred Kazin referred to him as "the master of American intellectual history". In his most famous book, The New England Mind: The Seventeenth Century (1939), Miller adopted a cultural approach to illuminate the worldview of the Puritans, unlike previous historians who employed psychological and economic explanations of their beliefs and behavior.
