John Harrison (1693-1776), an Englishman without any scientific training, worked tirelessly for more than forty years to create a perfect clock. The solution to this problem was so important that an award of 20,000 pounds sterling (equal to several million dollars today) was established by the English Parliament in 1714. Harrison won recognition for his work in 1773. Together with beautifully detailed pictures by Erik Blegvad, Louise Borden's text takes the reader through the drama, disappointments, and successes that filled Harrison's quest to invent the perfect sea clock.
