By Louise Borden

Illustrated by Erik Blevad

'For hundreds of years ships had been sailing to places far and near without really knowing where they were!'

John Harrison (1693-1776), an Englishman without any scientific training, worked tirelessly for more than forty years to create a perfect clock, so that sailors could accurately work out their location at sea. The solution to this problem was so important that a reward of £20,000 was established by Parliament in 1714. Harrison didn't win recognition for his work until 1773, when he was 80 years old.

Together with beautifully detailed pictures by Erik Blegvad, Louise Borden's storybook is set in and around the Royal Observatory of Greenwich. It takes the reader through the drama, disappointments and successes that filled Harrison's quest to invent the perfect sea clock.

Suitable for young readers of all abilities.
