Gwen Bell Artifact and Book Collection

Gwen Bell Artifact and Book Collection

This rare and important collection comprises written works and physical objects relating to early calculating instruments and methods. These works and objects are held in the permanent collection of the Computer History Museum after generous gifts in 2012 and 2014 by Museum co-founders Gwen and Gordon Bell. The text items in this collection comprise works written in French, German, Latin and English. It begins in the early 17th century (ending in about 1980) and includes dozens of works such as mathematical, accounting, farming, astronomy, merchant and engineering tables, monographs on slide rules, arithmometers, planimeters, sectors, Napier´s Bones, military compasses, telescopes, as well as later-day commentaries on these instruments and their history. The written works are available online in scanned (PDF) form using the search function below. The object collection was established as a complement to the rare book collection and both serve to document the early origins and development of human measurement and computation. Its objects include: abaci, sectors, linear, circular and cylindrical slide rules, mechanical and electrical/electronic adding machines and calculators, and replicas of early calculators such as the Pascaline and the Schikard. With both written sources and complementary physical objects, the Bell Collection offers researchers a unique window into the early origins and development of history´s most significant calculating devices and methods.
