In 1849—months before the term “confidence man” was coined to identify a New York crook—Thomas Powell (1809–1887), a spherical, monocled, English poetaster, dramatist, journalist, embezzler, and forger, landed in Manhattan. Powell in London had capped a career of grand theft and literary peccadilloes by feigning a suicide attempt and having himself committed to a madhouse, after which he fled England. He had been an intimate of William Wordsworth, Elizabeth Barrett, Robert Browning, Charles Dickens, and a crowd of lesser literary folk. Thoughtfully bearing what he presented as a volume of Tennyson with a few trifling revisions in the hand of the poet, Powell was embraced by the slavishly Anglophile New York literary establishment, including a young Herman Melville. In two pot-boilers—The Living Authors of England (1849) and The Living Authors of America (1850)—Powell denounced the most revered American author, Washington Irving, for plagiarism; provoked Charles Dickens to vengeful trans-Atlantic outrage and then panic; and capped his insolence by identified Irving and Melville as the two worst “enemies of the American mind.” For almost four more decades he sniped at Dickens, put words in Melville’s mouth, and survived even the most conscientious efforts to expose him. Long fascinated by this incorrigible rogue, Hershel Parker in The Powell Papers uses a few familiar documents and a mass of freshly discovered material (including a devastating portrait of Powell in a serialized novel) to unfold a captivating tale of skullduggery through the words of great artists and then-admired journalists alike.

In American History in Transition, Yoshinari Yamaguchi provides fresh insights into early efforts in American history writing, ranging from Jeremy Belknap’s Massachusetts Historical Society to Emma Willard’s geographic history and Francis Parkman’s history of deep time to Henry Adams’s thermodynamic history. Although not a well-organized set of professional researchers, these historians shared the same concern: the problems of temporalization and secularization in history writing. As the time-honored framework of sacred history was gradually outdated, American historians at that time turned to individual facts as possible evidence for a new generalization, and tried different “scientific” theories to give coherency to their writings. History writing was in its transitional phase, shifting from religion to science, deduction to induction, and static to dynamic worldview.
