Was invented by Prof Geoffrey Ingram Taylor, b 7/3/86 d 27/6/75, mathematician, scientist, and expert on fluid dynamics. His Alma Mater was Trinity College, Cambridge. According to Wiki his last publication was in 1969 age 83 but Wiki is wrong. I have his paper in edition 84, October 1971, of Eureka, the journal of the Archimedians, the Cambridge University Mathematical Society of which I was an undergraduate member in 1971. If I may quote three, non-mathematical, paragraphs and the final couple of sentences of his paper:

Archimedes was not only a mathematician who expressed his thoughts by means of numbers written on the sand but, as your name "Eureka" reminds us solved some essentially mathematical problems without using figures or symbols. When your editor asked me to make a contribution to "Eureka" to commemorate the publication of the last volume of my collected papers it seemed a good opportunity to describe the history of one of them which contains no symbols.

In 1923 I bought the 48 foot yacht "Frolic" which weighed 20 tons and drew 8ft 3ins of water. Her big anchor weighed 120lbs. While winding up the anchor the sails were not capable of controlling the boat and when anchored in 10 fathoms or more closer inshore with an onshore wind the effort involved in winding up the anchor to get under control before drifting ashore were too much for me. This and some problems connected with seaplanes provided the incentive to think about the design of lighter anchors.

After inventing the anchor I, together with my friends George McKerrow and W.S. Farren set up a small company to make them for our sailing friends. We called the company "The Security Patent Anchor Co" and would like to have put the word "secure" on the anchor but it is not allowable to register a common word in that way so we compromised and called our product "CQR". For a long time afterwards people asked me what the Q stood for.

...and all of us had other things to do, so we sold the company with the grant included in its finances to a firm which could use the grant for development. It still makes CQR anchors.
 
With the current anchor wars Prof Taylor is probably turning in his grave - well, resetting anyway.

I think Eric C. Hiscock would be too. He was my cruising guru when I started.

He was a fan of the CQR, in Cruising under Sail, 2nd edition, 1965, OUP he wrote

"It is wise when buying an anchor to specify a genuine CQR (as made by Simpson-Lawrence Ltd) rather than a "plough" anchor, a term which can cover a multitude of *******s"

Eric was allowed to publish that b-word without censorship.

I noticed that none of the plough anchors had the same plough angle as a CQR.

I have used several plough anchors, and most just did not want to dig in and get set. The only one that did was a 100kg model on a 50 ton schooner. Eric believed that no patent anchor under 35lb could set consistently, and that an average man should be capable of handling a 60lb anchor without any special gear.

Ah wooden yachts and iron men.
 
Thank you, dratsea, for that enlargement of the story of the CQR.

I copied it to my eldest son who also attended Trinity College and who writes as follows:


G I Taylor was also the innocent subject of the famous Trinity College spy story. When the Americans tested the H-bomb in the early 50s, footage of the explosion was broadcast on the news.

Taylor saw this footage, and was able to determine the size of the cloud by elementary methods (comparison with the size of people, deductions about various distances in the footage, etc). Having done this a straightforward dimensional analysis argument enabled him to estimate the amount of energy released.

He wrote this up and published it; we now know he was correct to within a factor of 2 or something.

The US government saw this, disbelieved such crude methods could give the right result, and suspected someone had leaked the right answer to him. So they lent on the UK, and the Cambridgeshire Police were dispatched to bring him in for questioning by MI5.

He explained carefully, and was soon released.

On the other hand, famous Russian spy Anthony Blunt was living in Trinity at the time; the resulting scare at seeing the police march in is said to have been one cause in the defections of the other famous Russian spies Maclean and Burgess to Moscow.
 
Thanks Guernseyman and also to parcifal for a copy of the 1934 (US) patent application. Prof Taylor was grandson of George Boole, of the eponymous algebra fame, was clearly exceedingly bright and suffered neither fools nor officialdom. Having met the fen bobbies I would love to have had a transcript of that meeting!
