Book excerpt: The dramatic human story of an epic scientific quest and of one man's forty-year obsession to find a solution to the thorniest scientific dilemma of the day--"the longitude problem." Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day-and had been for centuries. Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land. Thousands of lives and the increasing fortunes of nations hung on a resolution. One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution-a clock that would keep precise time at sea, something no clock had ever been able to do on land. Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer. Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.

Book excerpt: 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.

Download or read book Longitude s Legacy James Harrison of Hull 1792 1875 written by Chris McKay and published by CreateSpace. This book was released on 2015-04-22 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: The story of John (Longitude) Harrison is well known; how after many years of work, he developed a clock that would keep accurate time at sea. His goal was to win the Longitude prize, a glittering 20,000 offered in the Act of 1714. John's story is well recounted at all levels from the glossy booklet through the symposium proceedings, the popular book, the deep technical tome and the TV film. James Harrison, (James 4) was the great-grandson of James, John's brother. He worked in Hull making turret clocks between around 1826 and 1860. He died in 1875 and left at least 30 turret clocks that are known of today. James well knew his forebears horological knowledge and incorporated some of John's principles into his clocks. A key invention was a detached escapement that although it looked like a grasshopper, was in fact a gravity escapement. Other firsts for James were cast-iron wheels, expanding flys to regulate striking speed, an effective striking mechanism and skeleton cast-iron dials. But James 4 left more than what he bequeathed in his will, it was a spin-off from John Harrison's knowledge. This 'Longitude's Legacy' is exposed and explained. Much has been written about John Harrison, however, little has been told about the rest of the family. This book corrects some of this woeful shortfall providing a brief history of James Harrison, brother of the famous John. This James turned to bell hanging, bellfounding and milling after he had helped his brother with making of the regulators and the first sea clock. His son, Henry was a bellfounder too and was succeeded briefly by his son Henry. Henry died early in his life and the bellfoundry was then run by James 3. James 3 was eccentric but through a series of 100 plus letters in the Mechanics' Magazine provide a deep insight into his knowledge and character and this is explored in two chapters. A chapter is provided on the clockmaker William Wynn whose letters in the Mechanics' Magazine spurred responses from James 3. James 3 won two prizes from the Society for Arts, one for a detached escapement the other for expanding flys. His son, James 4 started with bells but then turned to turret clock making settling in Hull. He died in 1875 and left no issue. The books starts with necessary introductory chapters covering John Harrison and his quest for the longitude prize. Later family members are then covered followed by detailed information on James 3 and James 4. The largest chapter covers the clocks made by James 4. All known clocks are described and illustrated. In a somewhat unusual approach, over half the book is appendices. The majority of these are the letters that appeared in the Mechanics' Magazine and these are given for the interest of the reader and for the information of the serious researcher. Other details are letters written by James 4 and the various awards he received. The book will be of interest to anyone interested in clocks, particularly turret or tower clocks. Next, those who are fascinated by the Harrison story and want to know more about John 'Longitude's' wider family will find it useful. For churches that have a Harrison turret clock, and those who care for them, the book is a must. Finally local historians in the Lincolnshire, Yorkshire and Hull regions will discover more about their local man and clocks in their locality. Author Chris McKay is well known in the turret clock field both in historical and practical modes. It was in 1976 he saw his first Harrison turret clock and has been researching ever since. In explaining the book as 'a long time in the coming' he took advice from a friend and wrote the history 'just as it is'."
