Philbert Maurice d'Ocagne (1862-1938), French mathematician and engineer, the founder of the field of nomography; the graphical computation of algebraic equations. The present work explores all aspects of graphical calculation. The volume is part of a series published as a scientific encyclopaedia.

From the recently dispersed library of Erwin Tomash (1921-2012), American engineer recognised for his early pioneering work with computer equipment peripherals. His library consisted of over 3,000 books and manuscripts relevant to the history of computation, from medieval and renaissance works on arithmetic, finger-reckoning and the abacus, to the birth in the twentieth century of theoretical and practical computer science under Alan Turing.
