Harrison’s Journey to Solving the Problem of Longitude at Sea

Longitude was a significant navigational problem in the 18th century. Until the invention of the chronometer, sailors would measure time using a sextant and the position of the stars. This method was unreliable, and many ships were lost at sea due to navigational errors. To solve this problem, John Harrison dedicated his life to building a clock that could keep accurate time on long sea journeys. It wasn’t until 1761 that the marine chronometer was completed and successfully tested at sea.

Impact and Achievements

Harrison’s invention had an immediate and significant impact on the world. Accurate maritime navigation enabled faster, more efficient trade, and helped ensure the safe transportation of goods and people across oceans. Perhaps most notably, Harrison’s marine chronometer contributed to the rise of the British Empire as a maritime superpower.
