Longitude is the story of an unlikely genius, John Harrison. Self-trained clockmaker, he solved the problem of determining longitude on ships during the second half of the 18th Century. Determining longitude is trivial today with GPS, but for hundreds of years it was a big problem and inaccurate navigation was the death of thousands of sailors. There was even a Longitude Prize to be awarded for the man who could solve the issue.
In itself, the creation of the Harrison timepieces is a fascinating bit of science history. However, the real prize here is the political backstabbing at the highest levels of the contemporary British science community. The problem at hand was that various methods for longitude determination competed for primacy. Harrison, the relatively undistinguished watchmaker, found it hard to compete with the villain of the story, or in the author’s words the anti-hero. This man was Nevil Maskelyne, who seems to have been a bit of a bastard. To be fair, however, Maskelyne made significant contributions to navigation. Luminaries like Edmond Halley and Sir Isaac Newton also feature prominently.
I have been fascinated with geography since I was a child, and I thoroughly enjoyed this book. Well-written and without any excessive heft from unnecessary tangents, it should be good reading for everyone, but especially those with even a passing interest in navigation and maritime history.
