Lectures on the Science of Human Life

A later (1877) reprint edition, published in New York by S. R. Wells, of Sylvester Graham’s principal book-length statement of his full dietary, hygienic, and longevity system, first delivered as a lecture series and published in some form in the late 1830s. The archive.org digitized copy’s own metadata record confirms the creator (“Graham, Sylvester, 1794-1851”), date (“1877”), and publisher (“New York: S.R. Wells”) for this specific printing. Because different secondary accounts give the original publication year variously as 1837, 1839, or 1843, reflecting a genuinely complicated print history of serialized lectures and multiple revised editions, the archive cites the one copy whose bibliographic metadata it directly verified rather than asserting an unresolved original date, and describes the work in the case body only as dating to “the late 1830s.” Cited for Graham’s longevity and disease-prevention framing underlying the case’s “preserves health into old age” claim.
