Who would solve one of the most perplexing scientific problems of all time? This dramatic picture-book biography brings to life – with illustrations that glow with wit and inspiration – the fascinating story of the quest to measure longitude. While the scientific establishment of the eighteenth century was certain that the answer lay in mapping the heavens, John Harrison, an obscure, uneducated clockmaker, dared to imagine a different a seafaring clock. How Harrison held fast to his vision and dedicated his life to the creation of a small jewel of a timepiece that would change the world is a compelling story – as well as a memorable piece of history, science, and biography.
