The Manhattan Rare Book Company is offering this first-edition copy of An Elementary Treatise on the Differential and Integral Calculus from the personal library of Lord Byron’s daughter, the scientist and mathematician Ada Lovelace (1815-52).

Written by French mathematician Silvestre François Lacroix (1765-1843), the book was a key text driving the advance of English science and logic during the first half of the 19th century. It was translated into English in 1816 by Charles Babbage and two other students at Cambridge University.

The book is Lovelace’s copy from that first English edition and has around 35 ink annotations in her hand, plus some 20 pencil annotations by her tutor, the mathematician Augustus De Morgan.

Lovelace’s initials, AAL, are shown in gilt on the spine and the blind stamps of East Horsley Towers, seat of the Lovelace family, appear on the endpaper and title.

This mathematical text is priced at $135,000.
