Jesse Ramsden was one of the most prominent manufacturers of scientific instruments in the latter half of the eighteenth century. To own a Ramsden instrument, be it one of his great theodolites or one of the many sextants and barometers produced at his London workshop, was to own not only an instrument of incredible accuracy and great practical use, but also a thing of beauty. In this, the first biography of Jesse Ramsden, Dr Anita McConnell reconstructs his life and career and presents us with a detailed account of the instrument trade in this period. By studying the life of one prominent instrument maker, the entire practice of the trade is illuminated, from the initial commission, the intricate planning and design, through the practicalities of production, delivery and, crucially, payment for the work. The book will naturally be of immeasurable interest to historians of science and scientific instruments but, as it also sheds light on the increasing commercialisation of the scientific trade on the cusp of the Industrial Revolution, should also interest social and economic historians of the eighteenth century.

Francis Watkins was an eminent figure in his field of mathematical and optical instrument making in mid-eighteenth century London. Working from original documents, Brian Gee has uncovered the life and times of an optical instrument maker, who - at first glance - was not among the most prominent in his field. In fact, because Francis Watkins came from a landed background, the diversification of his assets enabled him to weather particular business storms - discussed in this book - where colleagues without such an economic cushion, were pushed into bankruptcy or forced to emigrate. He played an important role in one of the most significant legal cases to touch this profession, namely the patenting of the achromatic lens in telescopes. The book explains Watkins's origins, and how and why he was drawn into partnership with the famous Dollond firm, who at that point were Huguenot incomers. The patent for the achromatic telescope has never been satisfactorily explained in the literature, and the author has gone back to the original legal documents, never before consulted. He teases out the problems, lays out the evidence, and comes to some interesting new conclusions, showing the Dollonds as hard-headed and ruthless businessmen, ultimately extremely successful. The latter part of the book accounts for the successors of Francis Watkins, and their decline after over a century of successful business in central London.

Great Britain and Ireland enjoy a rich cartographic heritage, yet historians have not made full use of early maps in their writings and research. This is partly due to a lack of information about exactly which maps are available. With the publication of this volume from the Royal Historical Society, we now have a comprehensive guide to the early maps of Great Britain. The book is divided into two parts: part one describes the history and purpose of maps in a series of short essays on the early mapping of the British Isles; part two comprises a guide to the collections, national and regional. Now available from Cambridge University Press, this volume provides an essential reference tool for anyone requiring to access maps of the British Isles dating back to the medieval period and beyond.
