RC (DLC); at foot of text: “Hon Thos Jefferson”; endorsed by TJ as received 12 Dec. 1820 and so recorded in SJL. Enclosure: Chapman, Tables of Interest and Discount, calculated on the only true principle of 365 Days to the Year; and compared with the erroneous method now in use (New York, 1820).

Lebbeus Chapman (1785–1864), merchant and accountant, was born in Middlesex County, Connecticut. By 1808 he was partner in a New York City mercantile firm, and he was listed in that city’s directories successively as grocer, 1809–10, merchant, 1811–16, auctioneer, 1817–18, accountant, 1822, and secretary of insurance companies, 1825–34 and 1842–47. Chapman lived in Jersey City, New Jersey, in the mid-1840s before moving in about 1848 to Brooklyn. He died in Westchester County, New York (Frederick W. Chapman, The Chapman Family: or the Descendants of Robert Chapman [1854], 220–2; New York Mercantile Advertiser, 14 Sept. 1808; New York National Advocate, 25 Feb. 1817; Longworth’s New York Directory description begins Longworth’s American Almanac, New-York Register, and City Directory, New York, 1796–1842 (title varies; cited by year of publication) description ends [1809]: 130; [1810]: 136; [1811]: 52; [(1816)]: 154; [(1817)]: 145; [1818]: 79; [1822]: 118; [1825]: 36, 115; [1834]: 52, 186; [1842]: 145; The New-York City and Co-Partnership Directory, for 1843 & 1844 [(1843)], 67; Doggett’s New-York City Directory, for 1847 & 1848 [(1847)], 84; Doggett’s New York City Directory … 1848–1849 [(1848)], 85; New York Herald, 9 Jan. 1864; gravestone inscription in Green-Wood Cemetery, Brooklyn).

On this day Chapman sent the enclosed work to John Adams with a nearly identical letter (MHi: Adams Papers).

Chapman soon published Chapman’s Tables of Interest, calculated according to equitable and legal principles, at the rate of six per cent. per annum; showing the interest of any sum, from one cent to ten thousand dollars, from one day to three hundred and sixty-five days, from one to twelve months, and from two to thirteen years. With several other useful tables, explanations, &c. The whole comprising nearly one hundred and eighty thousand calculations (New York, 1821).
