At the Sign ofthe Oriental Lamp: The Musschenbroek Workshop in Leiden. 1660-1750. By Peter de Clercq. Rotterdam: Erasmus, 1997. Pp. 326; illustrations, tables, appendixes, notes, bibliography, index. Hfl. 69.50 (paper). Recent years have seen a growing number of historians coming to appreciate the material aspects ofscience and beginning to examine both the apparatuses with which observations, experiments, and demonstrations were made—optical instruments such as telescopes and microscopes, and philosophical instruments such as whirling tables and air pumps and, later, electrostatic machines—and the in strument-makers and dealers whose technical sophistication and business acumen turned rough ideas into commercial products. Pe ter de Clercq, a curator in the Museum Boerhaave in Leiden, has made an important contribution to this literature with this intelli gent and lucid account of the Musschenbroek workshop, one of the first important centers of production of instruments designed for the new natural philosophy. The text presents a close examination of the scientific instrument business at a time when production still occurred in workshops and when distribution was still by direct sales from maker to customer. Appendices offer a preliminary checklist of extant Musschenbroek instruments and transcriptions of the eight extant Musschenbroeck trade catalogs, some of which are known through only one copy. The Musschenbroek family setded in Leiden in the early years of the 17th century, establishing a brass foundry at the Sign of the Ori ental Lamp. Their involvement with science began around 1660, when students and faculty at the nearby University of Leiden asked Samuel van Musschenbroek to supply them with microscopes and anatomical instruments. Johann van Musschenbroek, who took charge of the workshop following his brother’s death in 1681, ex panded the range of instruments and circle of customers. The busi ness expanded still further under the leadership of Johann’s son Jan, who ran the firm from 1707 until his death in 1748. Jan’s most important customer was Willem ’sGravesande, a professor at the Uni versity of Leiden, who purchased numerous instruments for his ex periments and classroom demonstrations, and who depicted many ofthem in his influential textbook, known in English as Mathematical 142 Book Reviews TECHNOLOGY AND CULTURE Elements ofNatural Philosophy, confirm’d by Experiments, or an Introduc tion to Sir Isaac Newton’s Philosophy. Other customers ranged from an anonymous burgemeesterto the stadholderWilliam IV and his educated wife, Anne of Hanover. Most of the Musschenbroek’s customers were in the Netherlands, but some were in Sweden, Germany, Italy, and Russia (but apparently none in France or Great Britain). The air pump was the most emblematic instrument of the new natural philosophy and, not surprisingly, the Musschenbroeks’ most important product. Although very few shop records survive, de Clercq has unearthed evidence of about forty Musschenbroek air pumps and estimates that this represents about one-third to onehalf of the firm’s total production. He also argues that by 1700 the Musschenbroeks were the leading purveyor of air pumps in Europe. This aspect of the story began in 1675 when Samuel made an air pump for Burchard de Voider, the first Leiden professor to teach natural philosophy. Voider had recently made a trip to England, seen the air pump that Robert Hooke had made for Robert Boyle, and desired a similar one for his own use. This instrument is now in the collections of the Museum Boerhaave. In 1679 Volder’s suc cessor, Wolferd Senguerd, asked Samuel to build an air pump of a somewhat different form; this design proved to be substantially eas ier to manipulate than the English model. It is clear that the Musschenbroeks had close collaborations with academics and that several Musschenbroek instruments incorpo rated important innovations, but there are few records indicating who invented what. De Clercq’s answer to the credit question, which I believe to be correct, is that scholars and craftsmen often possessed...
