Sea Clocks: The Story of Longitude

(1) 4-6 Illustrated by Erik Blegvad. Spare prose outlines John Harrison's forty-year quest to determine longitude on a moving ship. Although the emphasis is on Harrison's doggedness, Borden presents the scientific problem deftly. Blegvad decorates the pages with both general scenes of the times (early eighteenth century) and specific incidents from the narrative. An afterword tells the fates of the principal players.
