Le calcul simplifié par les procédés mécaniques et graphiques...
Paris.
Gauthier-Villars, 1905.
Seconde édition [i.e. second edition].
vi, [2]. 228pp. Original publisher's limp brown cloth, lettered in gilt. Extremities rubbed and a trifle marked. Ink-stamps of Parisian booksellers M. Martin and C. Hauet to FFEP, half-title and title page, leaves browned, one leaf detached.
Philbert Maurice d'Ocagne (1862-1938), French mathematician and engineer, the founder of the field of nomography; the graphical computation of algebraic equations.
Le calcul simplifie is one of the earliest attempts to classify calculating machines by type, divided into mechanical, logarithmic and graphical. Ocagne's survey includes 'several one off-machines...such as the automatic multiplying machine of Leon Bollee (which used a mechanical form of Napier's bones) and the machine designed by Chebyshev' (Tomash and Williams II, p. 949).
