Marine Chronometers at Greenwich

The Marine Chronometers at Greenwich is the fifth, and largest, of the distinguished series of catalogues of instruments in the collections of the National Maritime Museum. Housed at the Royal Observatory Greenwich -- the 'home of time' and the Prime Meridian of the world -- this extraordinary collection, which includes the celebrated marine timekeepers by John Harrison (1693-1776), is generally considered to be the finest of its kind in existence. The book is however much more than just a catalogue, and includes an accessible and engaging history of the chronometer, revealing why these instruments were important in our scientific and cultural history, and explaining, in simple terms, how th...

John Harrison and the Quest for Longitude, in a revised and updated edition, is a fascinating account of the life and achievements of John Harrison, the man who designed and built the first accurate marine chronometers. Inspired by the prize offered in 1714 to provide a solution to the problem of determining longitudinal position at sea, John Harrison - a carpenter by trade - set out to develop portable clocks that would rival even the most precise watches of the time. His famous 'H' timepieces went on to revolutionise sea travel and save many thousands of lives. Now housed in the collection of Royal Observatory Greenwich, they are milestones in clock- making history. Beautifully illustrated with images that showcase the intricate detail and mechanisms of the timepieces,John Harrison and the Quest for Longitudetells the story of one man driven by the need to solve one of the greatest practical problems of his time.

Time Restored

This is the story of Rupert T. Gould (1890-1948), the polymath and horologist. A remarkable man, Lt Cmdr Gould made important contributions in an extraordinary range of subject areas throughout his relatively short and dramatically troubled life. From antique clocks to scientific mysteries, from typewriters to the first systematic study of the Loch Ness Monster, Gould studied and published on them all. With the title The Stargazer, Gould was an early broadcaster on the BBC'sChildren's Hour when, with his encyclopaedic knowledge, he became known as The Man Who Knew Everything. Not surprisingly, he was also part of that elite group on BBC radio who formed The Brains Trust, giving on-the-spot a...

A General History of Horology

A General History of Horology describes instruments used for the finding and measurement of time from Antiquity to the 21st century. In geographical scope it ranges from East Asia to the Americas. The instruments described are set in their technical and social contexts, and there is also discussion of the literature, the historiography and the collecting of the subject. The book features the use of case studies to represent larger topics that cannot be completely covered in a single book. The international body of authors have endeavoured to offer a fully world-wide survey accessible to students, historians, collectors, and the general reader, based on a firm understanding of the technical basis of the subject. At the same time as the work offers a synthesis of current knowledge of the subject, it also incorporates the results of some fundamamental, new and original research.

Following one of the most inspiring and fascinating stories linked to the Royal Observatory, Greenwich, this book centers on the life and achievements of John Harrison, designer and builder of the first accurate, marine timekeepers. Inspired by the official prize offered in 1714 to anyone who could solve the problem of finding a longitudinal position at sea, Harrison, already a clock-maker, produced his four famous timepieces. A fascinating account of one man driven by the need to solve one of the greatest practical problems of his time, this new edition features numerous illustrations, including the new memorial to Harrison in Westminster Abbey, as well as much updated information. Fresh insights on Harrison and his achievements are followed by a new section on Rupert Gould, the man who restored Harrison's timepieces in the inter-war years.

Harrison Decoded

Harrison Decoded: Towards a Perfect Pendulum Clock brings together the output of a forty-year collaborative research project that unpicked and put into practice the fine details of John Harrison's extraordinary pendulum clock system. Harrison predicted that his unique method of making pendulum clocks could provide as much as one-hundred-times the stability of those made by his contemporaries. However, his final publication, which promised to describe the system, was a chaotic jumble of information, much of which had nothing to do with clockwork. One contemporary reviewer of Harrison's book could only suggest that the end result was a product of Harrison's 'superannuated dotage.' The focus of this book centres on the making, adjusting, and testing of Clock B which was the subject of various trials at the Royal Observatory, Greenwich. The modern history of Clock B is accompanied by scientific analysis of the clock system, Clock B's performance, the methods of data-gathering alongside historical perspectives on Harrison's clockmaking, that of his contemporaries, and some evaluation of the possible influence of early 18th century scientific thought.
