The Dramatic Human Story of an Epic Scientific Quest
Longitude tells the extraordinary true story of one man’s forty-year obsession to solve the greatest scientific challenge of the eighteenth century — “the longitude problem.”
In an age when navigation determined the fate of empires, sailors could calculate their latitude with ease, but determining longitude — their exact east-west position — was nearly impossible once they lost sight of land. Countless lives, vast fortunes, and the dominance of nations depended on finding a solution. Despite centuries of effort by the world’s greatest scientists and astronomers, the problem remained unsolved.
Enter John Harrison, a self-taught clockmaker who dared to defy the scientific establishment. Against all odds, he imagined a mechanical answer to what everyone thought was an astronomical problem: a clock accurate enough to keep time at sea. Harrison’s relentless pursuit led to the creation of the marine chronometer — a revolutionary invention that forever changed navigation, saving lives and reshaping the modern world.
Longitude is more than a story of invention; it’s a timeless tale of genius, perseverance, and human ingenuity. Brimming with intrigue, discovery, and the spirit of adventure, this captivating narrative opens a window into the history of astronomy, navigation, and clockmaking — and celebrates one man’s unwavering vision that helped chart the course of civilization.
