Object Details
- Description
- This instrument has an open wooden frame held together with brass nails passing through metal bands. A wooden cross bar holds 13 columns of beads. Each column has two beads above the crossbar and five beads below. The beads are rounded, as on other Chinese abaci. There are no marks by a maker.
- This form of abacus was sold in combination with a book entitled Abacus Arithmetic by the Australian-born metallurgist, Stanford University graduate, and later Stanford professor of metallurgy Welton J. Crook (1886-1976). Crook became fascinated with the abacus on a visit to Hong Kong, and resolved to publish a clear exposition on the instrument in English. His short book was published in 1958 by Pacific Books in Palo Alto, California, and sold tens of thousands of copies. For a copy of this paperback, see 1989.0709.03. The abacus and the related book were given to the Smithsonian by Washington, D. C., clockmaker Elton L. Howe in 1989.
