William Barton, a lawyer and member of the American Philosophical Society, wrote this memoir of David Rittenhouse in 1813, seventeen years after the astronomer's death. The work is explicitly based on Barton's personal knowledge of Rittenhouse—he notes the 'personal regard' between Rittenhouse and President Washington—and on papers supplied by Rittenhouse's family. The book's full title promises 'sundry philosophical and other papers, most of which have not hitherto been published,' and the appendix delivers on that claim. Barton's narrative voice is formal and occasionally defensive, especially when addressing Rittenhouse's involvement with the Democratic Society of Philadelphia.

Barton's Dual Role as Biographer and Defender

Barton does not present himself as a neutral chronicler. He writes as a friend of Rittenhouse and as a participant in the same intellectual circles. This proximity gives the memoir an insider's texture but also a defensive tone. The most striking example is Barton's lengthy justification of Rittenhouse's election as president of the Democratic Society in 1793. He argues that Rittenhouse was chosen because he was 'a man of unimpeachable patriotism and integrity,' and that his acceptance of the role did not diminish President Washington's esteem for him. Barton goes so far as to assert that Washington's reluctance to accept Rittenhouse's resignation from the Mint 'yielded only to the Doctor's urgent solicitation.' These passages reveal Barton's anxiety about how Rittenhouse's political associations might be judged by posterity.

The Democratic Society Episode as a Test Case

The extended discussion of the Democratic Society occupies a significant portion of the excerpts. Barton traces the society's origins to the Jacobin Club of Paris, quoting Chief Justice Marshall's Life of Washington to establish the connection. He then carefully distinguishes between the society's founders—whose 'secret designs' he implies were 'inimical to the true interest of the country'—and its members, many of whom were 'highly estimable and meritorious citizens' who joined without knowing the society's real aims. This distinction allows Barton to defend Rittenhouse without defending the society itself. The passage is notable for its legalistic structure: Barton presents evidence, anticipates objections, and builds a case. It is the most argumentative section of the excerpts and suggests that the memoir as a whole may be as much a political apologia as a scientific biography.

The Appendix as a Window into Rittenhouse's Papers

The title page announces an appendix containing 'sundry philosophical and other papers, most of which have not hitherto been published.' This appendix is a key feature of the book, offering readers access to primary sources that Barton used in composing the memoir. The excerpts do not include the appendix itself, but its existence shapes the reader's experience of the main text. Barton frequently refers to documents and letters, and the appendix presumably provides the evidence for his claims. For a reader interested in Rittenhouse's scientific work, the appendix may be the most valuable part of the volume. Barton's role as editor of these papers is itself a subject worth noting: he selects, arranges, and presumably annotates them, making his editorial choices part of the historical record.

The Texture of Early American Intellectual Life

Beyond the defense of Rittenhouse, the excerpts offer glimpses into the networks of early American science and politics. Barton mentions Rittenhouse's correspondence with 'many distinguished men,' and the catalog subjects list 'astronomers' and 'physics' as primary topics. The memoir is set against the backdrop of the American Revolution and the early republic, and Barton's language reflects the period's formal, Latinate prose style. Phrases like 'the shock given to the humane feelings of the American people, by the murder of Louis XVI' reveal the emotional temperature of the era. Readers should expect a work that is as much about the intellectual and political culture of the early United States as it is about Rittenhouse himself.

Barton's memoir rewards readers who approach it as a layered historical document rather than a straightforward biography. The defensive passages about the Democratic Society, the reliance on unpublished papers, and the formal prose all invite scrutiny of Barton's motives and methods. Readers interested in the politics of early American science will find this a rich, if partisan, source. The appendix, though not excerpted here, is likely the book's most enduring contribution.
