I'm 66 today! They say time travels faster as you age, and my goodness, is it speeding past now! It's been fifty years since I first read about Johann Bessler and even longer since I began designing perpetual motion machines, and I thought I might have solved the problem long before now.
There is a nice succession of links in this story. I first read about Bessler in a book called "Oddities: A Book of Unexplained Facts", by Rupert T. Gould. He was a Lieutenant Commander in the British Royal Navy noted for his contributions to horology and a host of other things and was described as a polymath. He gained permission in 1920 to restore the marine chronometers of John Harrison, and this work was completed in 1933, aided no doubt by his photographic memory. Harrison was the guy who won (eventually) the British Board of Longitude's prize for establishing the longitude of a ship at sea. The prize was £20,000, a fortune in those days, and it was the publication of this prize in 1714, which it is believed was the inspiration for Johann Bessler's decision to ask the same sum for the secret of his own invention, the gravitywheel. (For more on Harrison and to see an animation of the grasshopper escapement see http://en.wikipedia.org/wiki/John_Harrison)
John Rowley, the finest instrument-maker in England at the time, was highly praised by Harrison in each of two volumes he published. The King of England, George l, who had already recognised Rowley's expertise in mechanics, and made him "Master of Mechanics to the King", requested a special sun dial from Rowley as a gift to Karl, the Landgrave of Hesse and Bessler's patron. Rowley took it to Kassel and installed at Karl's castle and during his visit was able to meet Bessler and see a demonstration of his wheel. He came away convinced of Bessler's claims and devoted the remaining years of his life to trying to replicate what Bessler had done.
Briefly, Rowley actually witnessed the wheel, he was a friend and colleague of John Harrison whose clocks were restored by Rupert Gould who also researched and published an account of Bessler, which I subsequently read. One cannot help but speculate that Gould must have had an interest in Bessler's machine and been aware of the connections between those involved.
As someone pointed out recently, mine and Bessler's obsession with the number 55 even includes my birthdate. 5th Feb 1945. There is a five and a two, so writing two fives makes 55 and then 1 and 9 is 10 plus 45 is 55 again! Amazing (not)!
Being the optimist that I am I am still convinced that Bessler's gravitywheel will be replicated and it can't happen a moment too soon. Time is, as I said, whizzing past at great speed and the need for this machine is growing at an alarming rate. Sticking to the 55 theme, I think I should have discovered the secret when I was fifty-five however I didn't and neither did anyone else. Maybe this year as I'm sixty-six and Bessler first exhibited his machine on the 6th June 1712, (six and six) someone will do it then, but of course next year, being the 300th anniversary since then, it would be even better.
No 'wheeling' for me today - just relaxing, being waited on - and the company of my very patient family. (patiently awaiting a working wheel!) But tomorrow I return to the task.
