Perry Gilbert Eddy Miller was an American intellectual historian and a co-founder of the field of American Studies. Miller specialized in the history of early America, and took an active role in a revisionist view of the colonial Puritan theocracy that was cultivated at Harvard University beginning in the 1920s. Heavy drinking led to his premature death at the age of fifty-eight. "Perry Miller was a great historian of Puritanism but the dark conflicts of the Puritan mind eroded his own mental stability."
