"We know, from his writings, that Harrison had difficulty expressing himself clearly ... Many of the concepts and devices (incorporated in his marine timekeepers) he was trying to describe had no name and he was constantly having to invent a new technological language. This, taken in combination with his humble origins, his lack of formal education, and his probable lack of social graces must have stood Harrison in poor stead before such an elite as the Board of Longitude, especially as very large sums of money were at stake." - from HARRISON
About a month ago, I viewed the excellent TV production of
Longitude [DVD] [2000] [US Import] that was based on the best-selling book (
Longitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time) by Dava Sobel. I became so interested in the subject of the invention of marine timekeepers to determine longitude by England's John Harrison in the eighteenth century that, during a recent trip to London, I made a special side trip to the Royal Observatory in Greenwich to see the first four of Harrison's clocks, which are there on display.
At ninety-six pages, HARRISON by Jonathan Betts is a most excellent souvenir of the Harrison exhibit which I purchased in the observatory gift shop. It's a first rate and concise, albeit brief, summary of Harrison's life (1693-1776), his clocks, his decades-long pursuit of the Longitude Prize first offered by Parliament in 1714, his prickly relationship with the government's Board of Longitude, and the 20th century restoration of his devices by Rupert Gould - all familiar to viewers of the television production. The operative words here are "concise", "brief" and "summary". Those desiring more should, I infer, read Sobel's book.
HARRISON is a slick production with a plethora of color photographs and diagrams, including snaps of the inventor's first four marine clocks (named by Gould H1, H2, H3, and H4). The clock photos are particularly useful as visitors to the Harrison exhibit are banned from taking pictures, something I found out to my disbelief and annoyance when confronted by an officious, blazered sentry after I'd innocently shot images of H1 and H2. Upon being asked for the reasons why, his explanation was that a camera's flash will damage the clocks (though I wasn't using that feature), copyrights could be compromised, and, most vague of all, because of "security" concerns. Well, I guess you get what you pay for; admission to the observatory is free. (For the same reasons, I presume, I couldn't photograph Admiral Lord Nelson's Trafalgar uniform - with the fatal bullet hole - down the hill at the National Maritime Museum.) Cheeky, insufferable Yank tourists - oversexed, overfed, over-moneyed, and obnoxious in Greenwich.
