Harrison´s Marine Chronometer, Clock Maker, Mathematics, Measurement of Longitude of a Ship, M Hinged Ascension
---------------------------------
John Harrison (24 March 1693 – 24 March 1776) was an English clockmaker. He invented the marine chronometer, a long-sought and critically-needed key piece in solving the problem of accurately establishing the East-West position, or longitude, of a ship at sea, thus revolutionising and extending the possibility of safe long distance sea travel in the Age of Sail. The problem was considered so intractable that the British Parliament offered what was at the time a huge fortune for a solution, a prize of £20,000 (roughly £6 million or €7.7 million in 2007 terms).
First following his father´s trade as a carpenter, Harrison built and repaired clocks in his spare time. Legend has it that at the age of six while in bed with smallpox, he was given a watch to amuse himself, supposedly spending hours listening to it and studying its moving parts. As clocks and watches of all kinds were rare and expensive at the time, and Harrison came from a family of only modest means, it is likely the legend is false or the timepiece was broken enough to be worth little.  | |
