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...
Time Restored
Biography of Rupert T. Gould, who during the 1920s and 1930s restored the timekeepers constructed by John Harrison (1693-1776).
Harrison
"With more than sixty illustrations, including annotated diagrams of the workings of the clocks, this book provides insights into Harrison's life and his achievements, as well as a look at Rupert Gould, the man who restored Harrison's timekeepers in the inter-war years"--Jacket.
John Harrison and the Quest for Longitude
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.
Harrison Decoded
This book is an exposition of the lesser-known work of one of the giants of the 18th century longitude story, the maverick clockmaker John Harrison (1693-1776). Harrison's background, methodology, and thinking. For those with a practical interest, the book is an excellent starting point for anyone wishing to make a clock of this type.
Harrison
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.
