"Longitude" is the dramatic human story of an epic scientific quest. The "longitude problem" was the thorniest dilemma of the eighteenth century. Lacking the ability to measure longitude, sailors throughout the great ages of exploration had been literally lost at sea. At the heart of Dava Sobel's fascinating brief history of astronomy, navigation and horology stands the figure of John Harrison, self-taught Yorkshire clockmaker, and his forty-year obsession with building the perfect timekeeper. Battling against the establishment, Harrison stood alone in pursuit of his solution and the £20,000 reward offered by Parliament.

Dava Sobel is an American writer of popular expositions of scientific topics. Her books include Longitude, about English clockmaker John Harrison; Galileo's Daughter, about Galileo's daughter Maria Celeste; and The Glass Universe: How the Ladies of the Harvard Observatory Took the Measure of the Stars about the Harvard Computers.
