John Harrison was a carpenter who 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, spending hours listening to it and studying its moving parts.
From these humble beginnings he invented the marine chronometer, a long-sought and critically-needed way of establishing the longitude, of a ship at sea, thus revolutionizing and extending the possibility of safe long distance sea travel in the Age of Sail.
In Total, John Harrison created 6 movements, H1 to H6, each more practicable and efficient than the last, packed with ingenious solutions to the problem.
After steadfastly pursuing various methods during thirty years of experimentation, Harrison finally designed and built the world’s first successful marine chronometers, the highly accurate maritime time-keeping instruments that, for the first time, allowed a navigator to accurately assess his ship’s position. – Dean Maryon, 180 Amsterdam
