He was survived by two daughters—Penelope Aubin and Pamela Packard—from his first marriage; his second wife, Marie (née Carpenter) Caskey Morgan, a historian; six grandchildren; and seven great-grandchildren. Career As an undergraduate at Harvard, Morgan was profoundly influenced by historian Perry Miller, who became a lifelong friend. Although both were atheists, they had a deep understanding and respect for Puritan religion. From Miller, Morgan learned to appreciate: The intellectual rigor and elegance of a system of ideas that made sense of human life in a way no longer palatable to most of us. Certainly not palatable to me... He left me with a habit of taking what people have said at face value unless I find compelling reasons to discount it...

Beveridge Award, and Inventing the People: The Rise of Popular Sovereignty in England and America (1988), which won Columbia University's Bancroft Prize in American History in 1989. Morgan has written a biography of Benjamin Franklin of which he made extensive use of The Papers of Benjamin Franklin and has written about at length.

Puritans Morgan's trio The Puritan Family: Religion and Domestic Relations in 17th-Century New England (1944), The Puritan Dilemma (1958), and Visible Saints: The History of a Puritan Idea (1963) restored the intellectual respectability of the Puritans, and exposed their appetite for healthy sex, causing a renaissance in Puritan studies, the more so because both Morgan and his mentor Miller were Ivy League atheist professors, adding to their credibility. Visible Saints, dedicated to Miller, was a reinterpretation of the Puritan ideal of the "Church of the Elect." Morgan argued that the criterion for church membership was not fixed in England.
