First published in 1923, this long-awaited edition of the definitive reference work on the marine chronometer contains additional photographs and many of Rupert Gould's later revisions and corrections. It deals comprehensively with the chronometers history and the earliest attempts to measure longitude while including exhaustive discussions and diagrams of the various mechanisms employed with details of their inventors. It is an extraordinary fact that the first machines capable of accurately determining a ship's longitude, a measurement the great Sir Isaac Newton considered to be a mechanical impossibility, were invented and built by an obscure Yorkshire carpenter named John Harrison (1693 1776). Amazingly, the latter was entirely self-educated and had never served a days apprenticeship to any clockmaker. The Marine Chronometer relates the remarkable story of John Harrison's marine timekeepers which eventually won him a %20,000 reward offered by the British Government for any method of determin
Rupert Thomas Gould (16 November 1890 – 5 October 1948) was a lieutenant-commander in the British Royal Navy noted for his contributions to horology (the science and study of timekeeping devices). He was also an author and radio personality.
Gould grew up in Southsea, near Portsmouth, where his father, William Monk Gould, was a music teacher, organist, and composer. He was educated at Eastman's Royal Naval Academy and then, from 15 January 1906 on, he attended the Royal Naval College, Osborne, and then the Royal Naval College, Dartmouth, being part of the 'Greynville' term (group), and by Easter 1907, examinations placed him at the top of his class. He became a midshipman, and thereby a naval officer, on 15 May 1907. He initially served on HMS Formidable and HMS Queen (under Captain David Beatty) in the Mediterranean. Subsequently, he was posted to China (first aboard HMS Kinsha and then HMS Bramble). He chose the "navigation" career track and, after qualifying as a navigation officer, served on HMS King George V, and HMS Achates until near the outbreak of World War I, at which time he suffered a nervous breakdown and went on medical leave. During his lengthy recuperation, he was stationed at the Hydrographer's Department at the Admiralty, where he became an expert on various aspects of naval history, cartography, and expeditions of the polar regions. In 1919 he was promoted to Lieutenant-Commander (retired).
On 9 June 1917 he married Muriel Estall. That marriage ended by judicial separation in November 1927. They had two children, Cecil (born in 1918) and Jocelyne (born in 1920). His last years were spent at Barford St Martin near Salisbury, where he used his horological skills to repair and restore the defunct clock in the church tower.
He gained permission in 1920 to restore the marine chronometers of John Harrison, and this work was completed in 1933.
His horological book The Marine Chronometer, its history and development was first published in 1923 by J.D. Potter and was the first scholarly monograph on the subject. It was generally considered the authoritative text on marine timekeepers for at least half a century.
Gould had many other interests and activities. In spite of two more nervous breakdowns he wrote and published an eclectic series of books on topics ranging from horology to the Loch Ness Monster. He was a science educator, giving a series of talks for the BBC's Children's Hour starting in January 1934 under the name "The Stargazer", and these collected talks were later published. He was a member of the BBC radio panel The Brains Trust. He umpired tennis matches on the Centre Court at Wimbledon on many occasions during the 1930s. In 1947 he was awarded the Gold Medal of the British Horological Institute, its highest honour for contributions to horology.
Gould died on 5 October 1948 at Canterbury, Kent, from heart failure. He was 57 years of age.
Longitude, a television dramatisation of Dava Sobel's book Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time, recounted in part Gould's work in restoring the Harrison chronometers. In the drama, Gould was played by Jeremy Irons.
Rupert T Gould was a genius, but also a man of bad temper, with a lot of problems, and a photographic memory that made him become crazy. He wrote this amazing book when he discovered that the marine chronometers needed more attention and study. Gould restored the John Harrison marine clocks, and also was an amazing Antarctic and Arctic Historian.
