Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Timeis a best-selling book by Dava Sobel about John Harrison, an 18th-century clockmaker who created the first clock (chronometer) sufficiently accurate to be used to determine longitude at sea—an important development in navigation.
