The Marine Chronometer
First published in 1923, The Marine Chronometer comprehensively outlines the earliest attempts to measure longitude. The definitive work of reference on the subject, it includes exhaustive discussions and diagrams of the important mechanisms, as well as details of their inventors.
The first machines capable of accurately determining a ship's longitude were invented by Yorkshire carpenter John Harrison (1693-1776). Astonishingly, the craftsman was self-educated and had never served a day's apprenticeship to a clockmaker. This tome outlines the remarkable story of Harrison's marine timekeepers, which eventually won him the £20,000 reward offered in 1714 by the British Government for any means of accurately determining a ship's longitude. Gould also looks, in detail, at the inventions of other important scientists and pioneers such as Huygens, Thacker, Sully and Leibnitz, as well as the work of professional watchmakers including Ditisheim, Ulrich, Earnshaw, Arnold, Berthoud, Mudge and Le Roy. His fluent style and expertise allow the reader to understand technical matters that, in the hands of another writer, might prove less than clear.
