The unexpected visitor
This post was written by Jonathan Betts
Almost exactly ten years ago I had John Harrison’s magnificent first marine timekeeper H1 in my workshop at the Royal Observatory. It was being dismantled for study, cataloguing and conservation for the new chronometer catalogue.
I had a film crew with me making a documentary, and they were becoming exasperated at constant interruptions to the filming. Finally another telephone call – a man was outside, asking if he could see me. Embarrassed, I assured the film team I would politely ask him to come back another time, but explained they had to come with me as I couldn’t leave them alone with H1.
Outside, the man apologised for arriving without warning and that he could come back if necessary. He introduced himself, offering his hand and just saying softly “Neil Armstrong”.
One of the film crew laughed and remarked 'Ha! I bet with a name like that you get lots of requests for autographs!' to which the unassuming gent simply replied: 'I’m afraid I don’t do autographs'.
It was at that point that we collectively realised that we were indeed in the presence of history. Suffice to say, all anxieties about filming schedules melted away and we all returned to the workshop (but with film cameras firmly switched off!)
Armstrong had long been a Harrison fan and he and his golfing friend Jim, hearing on the grapevine about the H1 research, had taken a detour from a sporting trip to Scotland, to make a pilgrimage to Greenwich.
For a wonderful hour or so we discussed Harrison and his first pioneering longitude timekeeper and it was clear Armstrong’s reputation was correct – reserved, yet of great intelligence and hugely well-informed; in short, a thoroughly nice man and not at all the showman one imagines when thinking of lunar astronauts.
I always asked visitors to sign my Visitors Book, but understood when Armstrong explained 'if you don’t mind, I’ll do it in capitals'.
Hearing that Harrison’s second prototype timekeeper, H2, would be next for research in the coming year, Armstrong returned and I spent a little more time with him, getting to know him a little better and was privileged to learn more of the Apollo 11 mission, from the horse’s mouth, as it were.
As he and Jim left on that occasion I asked Jim to sign my book again, and as they got back into their car, Jim whispered to me 'I think you’ll find Neil signed properly this time too'.
And indeed he had, something I shall always treasure.
The AHS 2015 Annual Meeting
This post was written by David Rooney
We welcomed over 100 members and guests to a packed full house at the National Maritime Museum for our 2015 Annual Meeting last Saturday. The sun shone, the atmosphere was buzzing, and we were given a superb day of talks and conversation.
The theme this year was ‘time and transport’ and, outside the museum, AHS members had brought a stunning selection of vintage cars to help set the scene.
During the morning session, we had fascinating talks by Peter Burt on RGS explorers’ watches; Tabea Rude and Erika Jones on zig-zag control; and Rory McEvoy on a Perregaux advertising campaign (apologies for the poor quality indoor photographs!)
After lunch and the society’s AGM, we heard from our new President, Lisa Jardine, on sea-going clocks; Jonathan Betts on polar expedition chronometers; and James Nye on the history of car clocks.
We were delighted to learn that Professor Jardine has recently been made an Honorary Fellow of the Royal Society.
We also marked the handover of the chairing of the society from David Thompson to James Nye by seeing David awarded a Fellowship of the AHS. Our huge congratulations and thanks to Lisa, David and James.
It was great to see so many members and guests from all around the country, of all ages and with all sorts of interests—represented also in the wonderful variety of speakers and lectures.
Thanks to you all for coming—and we look forward to the coming year with great excitement!
A second in one-hundred days: insanity or genius?
This post was written by Rory McEvoy
In 1775 John Harrison made a critical remark about Graham’s dead beat escapement, saying, of George Graham, that '…either he must be out of his Senses, or I must be so!'
Later in the same publication he stated of his own clock that '…there must be then more reason…that it shall perform to a second in 100 days…than that Mr Graham’s should perform to a second in 1.'
Keeping time consistently to within one second in 100 days was a degree of accuracy not achieved until around a century and a half later by mechanical clocks such as Shortt’s free pendulum system.
Harrison published his remarks in a vitriolic and virtually impenetrable book, the manuscript and transcriptions of which are freely accessible online.
On reading the book, which contains scattered descriptions of his method, the celebrated watchmaker Thomas Mudge, stated of Harrison that the book’s contents had '…lessened him very much in my esteem…' and that '…there are several things which he says about Mr Graham’s pallets and pendulum that are absolutely false…'.
The London Review of English and Foreign Literature described the work as 'one of the most unaccountable productions we ever met with' and went on to say that 'every page of this performance bears marks of incoherence and absurdity, little short of the symptoms of insanity'.
Harrison’s words were not taken seriously by any of his contemporaries and his radical statement about the capabilities of his pendulum clock, with its large pendulum arc, relatively light bob, and recoil grasshopper escapement, remained largely unexplored until the 20th century.
Then, in 1977, a number of horological scholars, who became known as The Harrison Research Group, began to look at his theories afresh.
Martin Burgess’ Clock B is a product of this collaborative research and represents one of the most significant historio-technical investigations in recent years. Recently, numerous experiments have been tried on the clock at the Royal Observatory, Greenwich with exciting results.
To learn more about this intriguing project please join us for a special one-day conference on July 12 2014 at the NMM.
The AHS Annual Meeting 2014
This post was written by David Rooney
On Saturday 17 May, 120 AHS members and guests packed into the National Maritime Museum’s lecture theatre for our 2014 Annual Meeting. It was a sell-out crowd, and what a day we all enjoyed.
Those who couldn’t make it missed a couple of important announcements which I’ll pass on here in advance of them appearing in the next Antiquarian Horology .
The first announcement came from Sir Arnold Wolfendale, the 14th Astronomer Royal, who has been a tireless supporter and champion of the AHS since becoming our President over 20 years ago.
Sir Arnold, whose inspiring and lively lectures on cosmological aspects of timekeeping have been enjoyed by so many of us over the years, has decided to stand down. We wish to thank him hugely for all of his support over the years and wish him well in his ‘retirement’ from the presidency.
David Thompson then announced that Professor Lisa Jardine, the eminent historian, writer and broadcaster, has agreed to become our new President, and takes over immediately.
Lisa is teaching this term at the California Institute of Technology in Pasadena (home of the recent Time For Everyone symposium), and could not be present in person, but she sent her best wishes and looks forward to meeting us in person in the near future.
We are delighted and honoured to welcome Lisa to the AHS presidency.
The other major announcement of the day was the launch of the brand new AHS website. We urge you to take a look. It is the culmination of many months of patient work by a small AHS team plus our designers, Latitude, and our web developers, Blanc, and has been fully funded by a donation from council member James Nye.
At the heart of the website is a remarkable new resource for AHS members. We have digitized the entire back catalogue of Antiquarian Horology, and every single page we have ever published, dating back to the first issue in 1953, is now available and searchable online.
We are thrilled to bring this invaluable resource to members and wish to thank our great friends and technology partners, the Deutsche Gesellschaft für Chronometrie in Germany, for carrying out the scanning and indexing work at an extremely preferential rate.
You can find the new website at our usual address, www.ahsoc.org, and to use the digital journal, simply log in to the members pages with the password printed on the back of your AHS membership card.
The addition of the journal archive is an extremely valuable new member benefit which must surely be worth the AHS subscription alone, so do please encourage your friends, colleagues and clients to join (don’t forget that you can join online using credit cards, debit cards or PayPal in just a few easy and secure clicks).
A tiny housekeeping note. The AHS blog on which you are reading this post has now moved to blog.ahsoc.org. The old address will still work fine, but if you subscribed to posts using an RSS feeder, we’re afraid you’ll need to re-subscribe from the new location. Sorry about that.
There’s never been a better time for reform!
This post was written by James Nye
A gauntlet has been laid down. Across Europe, thoughtful people are busy working up ingenious ideas for a competition devised over an extraordinary April weekend in southern Germany.
Each year, several dozen of the electro-horo-cognoscenti gather in Mannheim-Seckenheim for an event organised by Till Lottermann and Dr Thomas Schraven.
The fifteenth of these gatherings—a combination of market, lectures and much eating, drinking and good conversation—saw a new visitor who brought many interesting items, not least several hundred new-old-stock Reform movements, tissue-wrapped and boxed.
Alert readers will recall an Antiquarian Horology cover featuring a classic example of the Reform calibre 5000 movement, and a fascinating accompanying article.
As David Read comments, these Schild movements are ‘without doubt the best known and most commercially successful of all the many varieties of electrically-rewound clock movements’ from the 1920s onwards. The calibre 5000 is a lovely object, jewelled, with damascened plates, and micrometer regulation.
Nye’s theorem proposes that hi=as*bc/ebw where hi stands for horological inventiveness, as represents afternoon hours of sunshine, bc denotes beers consumed and ebw stands for evening bottles of wine.
With a lively group, talk over two sunny days and late evenings turned to possible creative uses for virgin Reform movements.
Given their looks, the mechanism must remain visible, but the motion work is to the (unremarkable) reverse. This led to discussions of projection clocks, or elaborate gearing to present time in the same plane as the movement, but to one side.
There was even intriguing talk of a large scale tourbillon. More detail than this presently remains closely held, but a competition to determine the best use was announced, to be decided in Mannheim in April 2015.
Reform is the order of the day.
