The fascinating story of John Harrison who, in the 18th century, believed he could make a clock that would work on board a ship—and so solve the problem of finding longitude at sea.
The ever-reliable Ian Hart appears in Part 2 as Harrison's now-adult son and apprentice, and Longitude approaches its dramatic climax with the exhilarating tension of a first-rate thriller. Rallying after sickness to prove the integrity of their marvelous seafaring chronometers, the Harrisons still had to fight for official recognition, and Gould's restoration of the Harrison clockworks provides a fitting coda to this exceptional story about the thrill of discovery and the tenacity of remarkable men.
