Someone's Trash is Our Treasure

The Collector as a Preserver of Material Culture

Nicola Marras Manfredi and Wolfgang Irler have organized the 22th Oughtred Society International Meeting.

The Oughtred Society International Meeting event took place September 16th - 18th, 2016 at the MUSE Science Museum in Trent, Italy.

Many mathematical devices and slide rule were displayed for this IM 16, International Meeting of Collectors of Historical Calculating Instruments.

The theme for the 22th IM 16 of the Oughtred Society takes its inspiration from the comparison of extinct species to the extinct technology of mechanical calculating devices. We want reconsidering these historical calculation-related artifacts, putting the main emphasis, not on the achievements of past technology, but on the "material culture", taking into account the historical context that makes these artifacts worthy to be collected, analyzed, and used to explain its evolution.

Consequently, the actual collector may be considered as having equal rights to a paleontologist who digs for fossil remains or an archaeologist who searches for human artifacts, rummaging in forgotten cellars and flea-markets. What someone had thrown away became the collector's treasure.

A thank to the editors of the IM16 Proceedings. Editing a text it is a long process, time-consuming and unpaid. Without the help of David and Donna Sweetman, Jerry McCarthy and Mark McCormick, we would not have published anything!

The Oughtred Society

The Oughtred Society was founded in 1991 by a group of slide rule collectors and is dedicated to the preservation and history of slide rules and other calculating instruments. Over the past three decades it has evolved to an international organization with members in 20 countries.

The Society is a non-profit educational organization. Society goals include the dissemination and sharing of information and encouragement for collectors. We are affiliated with organizations in the United Kingdom, Germany, The Netherlands and Italy. Our activities are carried out by members who volunteer to do various tasks and projects. Membership is open to anyone.

The Journal of the Oughtred Society, published twice annually, is available only to members of The Oughtred Society. This internationally acclaimed journal is the most authoritative source on slide rules and other calculating devices.

These informations come from the Oughtred Society official website.
