    A good read, and even the clickbait about historic spam seems to be merited!

    One little bit of history that may be missing: were they involved (and if so how) in Blighty's famously successful espionage on German communications in the lead-up to war?

    1. smudge Silver badge

      If you mean the Zimmerman telegraph, which helped to bring the USA into WW1, it seems that that was intercepted at the Porthcurno relay in Cornwall.

      https://en.wikipedia.org/wiki/Zimmermann_Telegram

      Although it's not clear from your post what espionage, or indeed which war, you are referring to.

      1. I ain't Spartacus Gold badge

        I immediately thought of the Zimmerman telegram, when the article stated the Telegraph Office had had a relatively quiet WWI. Which led to a quick bit of Googling to refresh old memories.

        It's interesting how things was different back then.

        Britain cut German cables so as to force them to broadcast by radio, so we could crack their codes. And also to be annoying.

        Comms discipline was pretty poor back then. Codes weren't all that good, or rigorously designed. And lots of stuff got sent in the clear. One reason the Germans trounced the Russians so badly in Poland and East Prussia in 1914 was that the Russian HQs kept issuing orders by radio with no encoding whatsoever. Also the German High Seas Fleet did their internal communications by radio when in port! Rather than by runner or ship-to-ship cable, which couldn't be intercepted.

        The US offered the Germans some telegraph help. Take uncoded messages to their embassy in Berlin, and the US would re-transmit them over their "secure" lines. Said lines went via Cornwall for amplification, and so were sneakily copied by the British. *Ahem!*

        The Germans managed to persuade the US ambassador to send the Zimmerman telegram in code - well they couldn't exactly get the Americans to transmit their plans to pay Mexico to invade them could they? Awkward!

        So the British government spent a few months looking for plausibly deniable ways to get this to the US, without admitting spying on their diplomatic traffic or that they'd broken the German codes.

        Which made it harder to say it wasn't an evil British forgery. But then Zimmerman went and publicly admitted it was genuine anyway! Despite German diplomats in the US and Mexico trying to say that it was a Britihs fake. D'oh!

        Also, what a stupid idea! Mexico was only just (mostly) stopping its own civil war. How the hell did the Germans expect them to be able to conquer Texas and New Mexico? Even if they were a united country there was no way they were going to be able to beat the US army, and it was obvious that they would know that too. So why make the offer, and risk Mexico telling the US about it and bringing them into the war quicker? Unrestricted submarine warfare was likely to bring them into it eventually anyway. It's a strange old story...

            Cuddles,

            Well lots of bad stuff happens now. But people like the military are a lot more aware about it. And normally even politicians nod to security - although people like Trump insisting on using their own mobile probably isn't that unusual. Didn't Obama demand they make him a secure Blackberry, because he didn't like the available choice of secure phones?

        2. Claverhouse Silver badge

          Without implying any callous attitude on the part of the Great General Staff, any success, let alone conquests, for the Mexicans --- even with heavy casualties---, would be less important than the merest diversion to keep the US preoccupied for a few months.

          The Idiot Press would have worked into a froth about Mexicans, American Statesmen would have planned gigantic Walls to no purpose, and Pershing would have matched up and down Mexico.

          Americans have always been a mite touchy about their beloved little brother down past the Rio Grande, and their tiny minds would have exploded at a full invasion.

          Anyone remember how in 1960s to 80s American films dealing with Mexican revolutions and the like, the hosts of unbelievably incompetent uniformed Mexicano mooks had a few sinister German advisers attached to each squad ? Generally in white undress uniform, with nose-rim eyeglasses.

          1. I ain't Spartacus Gold badge

            Claverhouse,

            Oh I fully understand why the Germans would want Mexico to invade. And the pre-WWI US army was absolutely tiny. But the Mexican army wasn't that much bigger, and despite years of intermittent civil war doesn't seem to have been particularly effective or done much with all that potential combat experience. Plus I think the Mexicans got a lot of their weapons from the USA - and the Germans were in no position to ship them any.

            As I understand it the Mexican government came to that conclusion pretty quickly, and also wasn't particularly optimistic about holding on to Texas even if by some miracle they were able to take it and hold it long enough to get it in the peace talks (should the Central Powers win).

            Hence it's such a transparently bad offer that there seems no possible reason to take it. Or in fact to do anything else than try and win brownie points from Washington by telling them all about it.

          That was true during WW2, but in WW1 they cut the direct undersea cables, forcing them to use alternative routes that tended to be easier get access to... hence the Zimmerman telegram being intercepted at Porthcurno because it was one of the few transatlantic routes left

          1. I ain't Spartacus Gold badge

            Well the Zimmerman telegram went via the US embassy in Berlin. And apparently Wilson offered this route to communications as an aid to peace talks - the deal being all messages had to be un-coded. They persuaded the US ambassador to allow them to send that one in code, as it would have a tad embarrassing otherwise...

            Which means most of their stuff was still going to have to go via radio. Or sent on the commercial networks using subterfuge.

    2. Thoguht Silver badge

      I'm not sure about the lead-up to war, but during the war the telegraph office was certainly involved in anti-espionage work.

      One case I vaguely recall involved a simple three word telegram (not unusual because you were charged per word) being sent to a recipient in a neutral country stating "Grandfather is deceased". The telegraph operator, thinking the wording was a bit strange, contacted the intelligence services and was told to send the telegram but follow it with another one saying "Grandfather is dead". The reply came "Is grandfather dead or deceased?" The original sender was immediately arrested, found to have been spying on British fleet movements, and shot.

      Re: A great read

      Indeed.

      I am just reading Erik Larson's "Thunderstruck", a crime novel with bits of historic facts, and one important part is about Marconi's "invention".

      I'm using quotes because I didn't know how little he knew about physics (and next to nothing about maths), his success was mostly due to very good instincts, hard work, perseverance, and luck.

      And connections : I also didn't know his mum was a Jameson (whiskey), which explains why he came to London instead of a civilized place like, say, Paris, and was quickly introduced to the right people, like W. Preece

      The CTO has obviously an important part in the story.

      I'm finishing the part where he and Preece fall out, because of, you know, Big Money. Quite sad, as Preece appears to have been the prototype of the Honest Engineer, more interested in finding Useful Stuff and bringing progress to humanity- or at least to the UK telecoms.

      There is also an interesting bit about the clash between the "experimenters" like Marconi and Preece and the "theorists" or "Maxwellians" such as Lodge.

      All in all a funny read even if Larson digresses quite a lot, by his own admission.

      Hertz, Faraday, Marconi, Branly,... Great times.

    BT Archives worth visiting when they next have an open day

    I visited the BT Archives recently when they had an open day. Lots of interesting stuff about early telephony. One map shows the German telelphone/telegraph cables which went along the English Channel to connect Germany to North and South America. One of our first actions when the first world war broke out was that we cut all these German cables and so cut them off from a large chunk of the world. It must have required quite a bit of intelligence and prior planning to have done that.

      I haven't looked if they're doing it, but Open House London is this weekend.

      So if there's any BT open days going to happen, that's a really likely time for it to be. That's when London Underground let you go interesting and unusual places too - but those tend to book up ahead of time, as they're so hard to get on. But the BT archives are less likely to be over-subscribed.

      The London one is always a week before or after the national one, and there are alwasy loads of interesting places open that normally aren't.

      Sorry - just my little bit of advertising. As I remembered that it's around this time every year.

          Obviously a lot of places that are open to the public anyway put themselves on it. But you also get interesting stuff from the railways, London Underground, and I see the John Radcliffe (Oxford) vascular imaging clinic are offering a tour for some reason. So if you're into ultrasound and radioactive tracers - go and knock yourself out.

          The number of people who could visit a building is unaffected by the number of other buildings that are open.

          The number of people who want to visit a building is arguably increased by having a special open house weekend which is publicised https://openhouselondon.open-city.org.uk and which people plan to go to every year. I've been going for 20+ years and I've seen some fascinating places.

        Perkins Braillers are still the thing. Most blind kids will get laptops and all the special software. But Braille embossers are still enormous and bloody noisy - my Mum had one and it was a bugger to get software. If you just want to do a few little labels, nothing beats a Braille embosser.

        The year after she retired from teaching, she took one of her ex-pupils to the Roald Dahl museum in Great Missenden - and complained to them about the lack of Braille labelling on everything. Though I think they opened some cabinets and let the kid touch some of the exhibits.

        So Mum did all their labels for them, on her Perkins Brailler onto plastic sticky labels - and in return they gave her a golden ticket that got her unlimited entries. Which got used on a few other ex-pupils and the grandchildren.

          Perkins

          My Mum, who was not blind herself, at age 60 or so, took up Braille transcription for the Library of Congress. She had to get certified (Braille isn't just letter-for-letter, it's a shorthand) and take a test, transcribe part of a document with no errors, etc. For several years before her death, she would receive portions of books, and transcribe them with her Perkins Brailler to foot-square sheets of Braille, which she would mail off (postage-free) to the LOC. She used it so heavily that I had to replace a number of keyboard springs broken through heavy use. I called Perkins and they cheerfully supplied replacement parts!

          When she died, I again called Perkins, offered them the Brailler back, to be given to a needy student, which they gratefully accepted. Turns out, they do a good bit of business, the students build the machines, they're sold at cost, they are designed to be user-repairable and quite rugged. Apparently, there's now a "version 2", but the classics are still very much in use.

          I go past Perkins every day on my commute. Good people doing good work.

        Telegraphs are still used control some equipment inside expensive containment areas like matter colliders and reactor containment vessels.

        The guy who created the system needed to talk to devices using one wire (as each additional wire could cost upwards of a million dollars to install), and was a amateur radio operator who knew Morse code. His idea was to use Morse code to talk to the equipment inside much like a serial port was used at the time. His boss insisted that he apply for a patent on the concept and after the patent office had correctly rejected most of the claims as being obvious, all he was left with was a patent for the telegraph just like the system used 100 years before.

        There are still plenty of pairs of signal boxes linked by telegraph on the UK's railways. Signallers communicate with each other by means of single-strike bell codes then use block instruments to track and repeat the status of the line: whether it's clear, occupied or the default status of line blocked (indeterminate).

          Re: block instruments

          They were certainly in use at Harrow-on-the-Hill when I was a signal engineering apprentice (early 1970's). These were used to signal trains between there and the next box along (Neasden Junction presumably) on the British Rail Marylebone line only. The rest of the site used (nearly*) conventional Underground signalling - including the next leg of the BR line up to Moor Park (which is shared with the Metropolitan line). (*The line up to Amersham had four aspect signalling, and the fog repeaters had light blue aspects instead of green to prevent confusion).

          I can't remember whether there were block instruments at Amersham (where the BR line continues on to Aylesbury), presumably there must have been.

    Off topic?

    I went up the BT tower when it still had a public gallery. I still have the brochure somewhere, what impressed me was the size of the power feed bus-bars. IIRC (unlikely) they had about 10 (now I'm guessing) 2ft width x 1inch thickness aluminium bars stacked so that there was a 1 inch gap between the bars. (Imagine a 90° change of direction of the bars)

    A friend of mine lived adjacent to the tower and when the IRA bombed it, pieces were raining down on his house. He thought that the tower was going to fall on his house. A case of brown pyjamas maybe :(

    Fun fact number two:

    A WW2 aeroplane nerd told me that at the start of WW2 there were 20 anti-aircraft guns guarding the Scapa Flow and only six guns for the whole of London.
