Burning Cuyahoga: A Technical Appendix to Postblogging Technology, June 1956
The Wiki entry on the Cuyahoga River of northeastern Ohio is actually pretty interesting. The word seems to be Seneca. The river isn't long, but is important, running through the major Ohio city of Cleveland. It appears to have been the western border of the Haudenosaunee, but local archaeologists and historians are having difficulty sorting out the pre-contact ethnology of the Whittlesay cultural horizon, which might be Fort Ancient, which I think is thought to have been Siouan, but also Algonquin-speaking and associated with the Monongahela horizon, which is thought to have ben Iroquoian. Historically both Ottawa and Wyandot (Huron) communities are know, which for me raises the question of early Catholic parochial activity in the region. We're told that it isn't surprising that the attested first Catholic church in Cleveland, St. Mary's-on-the-Flats, has no history prior to 1878, even though the Diocese of Cincinnati was erected in 1821, well before the beginning of significant Irish Catholic emigration, a bit of an issue in its own right, and the parish had a resident pastor from 1835, with St. Mary's being dedicated on 7 June 1840 by a visiting French bishop, who seems to have made something of a revivalist tour through Catholic, and especially French Catholic America. So in other words the early Catholics of Cleveland were probably Metis rather than more respectable Irish Catholics and that's probably why the early colonial history of the region is so obscure.
The same can't be said for the Cuyahoga Fire of 22 June 1969, which turns out to be No Big Deal in the long history of at least thirteen Cuyahoga river fires, but a very big deal and watershed (did you see what I did there? Because I did it!) in American environmental history. Or at least that's the impression the Wiki gives. It's the sheer density of industrial development along the river, rather than any particularly egregious polluter, that accounts for the frequent fires. And, notwithstanding the subject of this week's post, it was bog standard POL surface slicks that caught fire and not sudsing organophosphate artificial detergents, such as are responsible for the "foaming rivers" of Jolly Old England going back to the Fifties. Honestly, when I opened the "Cuyahoga River" article I was expecting to hear something about mass market U.S. laundry detergents, foaming rivers, and eutrophication, not oil slicks catching fire. I was especially not expecting to hear about rhetorical links with narratives of decaying urban centres and, sigh, structural racism. Whatever you might think about burning rivers, it turns out to have been a strong driver of White Flight.
Which is kind of too bad, because there's a lot of hinky stuff going on with organophosphates!

The Chairman's Little Helper: A Technical Appendix to Postblogging, May 1956
(If you're wondering over The Engineer, my tentative theory is that it briefly appeared on the Hold shelves during my August trip and has by now been retracted back into the stacks, possibly without notice of same reaching my Library Account, although it is at least as likely that I just didn't register some notification or email. I shall try again.)
I thought about running this last week, but, on the other hand, it's officially a thing when there's two different articles about barbiturates in the same week. The age of Homo medicus! (Which turns out to be some dietician-anthropologist-paleontologist science thing, my apologies to Edward H. Hagen for not searching out some more authentically patronising Fifties label for patients using psychotherapeutics.

Tinkertoy to Dexion: A Technical Appendix to Postblogging Technology, April 1956
By susiq5555 - ebay #120137669430,

"Tinkertoy" is the title because it is what comes to mind when I think about the building sets of my earliest childhood. (Next up are my rich cousins' Lego sets, please don't tell them I called them "rich.") I do not, however, have much of a sense of a Tinkertoy set, as opposed to oddments at the bottom of a toy chest. Tinkertoy Construction Sets are an American product dating to 1914. Their signature feature is the use of wood, which makes it easy to implement wheels and pulleys with child friendly components, but there were lots of wood construction sets. The issue here, it tuns out, is the non-wood one.
The departure point for today's appendix is the use of Dexion components for field repairs of DC3s.
The other inciting even this week is that quaint Danish general strike over the forty hour week. Not only is this sure to lead to a wage-price spiral and inflation, but now Britain's supply of butter and bacon is in trouble! And since there isn't much going on in Denmark to my knowledge except bicycling, which they have to share with the Netherlands, and Lego, we might as well go there. And the ever worthy Meccano, of course.

Missile Gap? A Technical Appendix to Postblogging Technology, February 1956
Long time readers will be tired of me bleating about how I was sold a bill of goods in high school about how "we," meaning of course the United States --and, by the way, those Latin American whiners complaining about how "America" has been recently appropriated to mean just the U.S. are 100% correct, to my surprise, but it was the British press that led the pack-- were surprised by the unexpected space technology gap signaled by the shocking surprise of Sputnik. (That was as shocking surprise.) For me, the takeaway point, twenty-four years later, was that it was still necessary for every bright child in a provincial high school to major in the physical sciences if "we" were to have any chance to catch up.
And you will of course heard from me that this is not true, that the satellite launches undertaken for the International Geophysical Year were scheduled years in advance. Sputnik was no more of a surprise than the T-34's appearance on the battlefield, the first Soviet atomic test in 1949, or the defection of Kim Philby, to name three. It turns out that our received history of the Fifties has been sucked of nuance and detail for any number of reasons. In the case of Sputnik, and the missile gap in general, we can even see the explanation. The Eisenhower Administration's attempt to rein in military spending in the 1956-57 fiscal year led to an industry response that was coordinated with congressional Democratic majorities to produce an airpower-centred arms race. (Much to the disappointment of those wanting an infantry-centred arms race.)
But that isn't the limit of my disillusionment. Missile programs might be a silly starting point, but I am, er, beginning to doubt the value of the American experiment.

Line Scanning: A Technical Appendix to Postblogging Technology, November 1955
As the electrons travel down the tube, they interact with the RF signal. The electrons are attracted to areas with maximum positive bias and repelled from negative areas. This causes the electrons to bunch up as they are repelled or attracted along the length of the tube, a process known as velocity modulation. This process makes the electron beam take on the same general structure as the original signal; the density of the electrons in the beam matches the relative amplitude of the RF signal in the induction system. The electron current is a function of the details of the gun, and is generally orders of magnitude more powerful than the input RF signal. The result is a signal in the electron beam that is an amplified version of the original RF signal.

Jordan River Is Deep and Wide: A Technical Appendix to Postblogging Technology, November 1956
So we are sorted at work about how this humble blogger is going to be plugged into our current workplace "the retail emergency is forever" scheme:
Saturday: 6-230; Sunday, 10-6:30 "Need experienced people in the mid shift on our busiest day," until Saturday at 3PM, at which time it was changed by text message to 6-2:30: Monday, 6-2:30: Tuesday: 6-2:30: Wednesday, 1:30-10 "The DM will visit tomorrow, we need the department in good shape." It's good to be wanted at work, but if I asked you to guess what I did on Thursday, and you answered, "Managed to sleep for six hours, then sat on the couch eating stale chips and watching Youtube clips, taking a break every hour to nap," you would be right! As it turns out, I wouldn't have been able to finish it on Sunday morning, either.
And this is why this post is largely in response to things Newsweek will cover in our next installment of postblogging, which was about one quarter done Saturday afternoon when I gave up and went out for dinner.

The point of this week's technical appendix is that some people say that British Airways ruined the British aviation industry by rejecting British planes, and some people say that British aviation ruined British aviation by forcing the Britannia on British Airways. In the spirit of the Internet these days, I'm going to present the case that it's actually "both"! And along the way I'm going to drag in some infrastructure projects of the mid-Fifties that are also having a continuing impact in a little part of the world that I like to call "the Middle East," which you probably haven't heard of. We're very geographically educational around this blog!Saturday, December 20, 2025
Another Thing About Balloons: A Technical Appendix to Postblogging Technology, August 1955
So if the Soviets said, in the summer of 1955, that they were going to launch an Earth satellite in September of 1957 as part of their contribution to the International Geophysical Year, and their progress was fairly public, and they actually proceeded to launch said satellite, where exactly is the "Sputnik surprise?" One way to answer this question is that the button for enabling Google's contextual links feature has moved down to the text box, and that I accidentally clicked it, and it added the links in the first line, and, really, their sheer inanity says it all.
Another is to post this clip of Tom Lehrer making fun of
well, everybody, really. America, maybe. This is an extremely well known clip because just about everybody is embarrassed by the fact that a Nazi war criminal ended up in a prominent role in NASA. And then there's the ICBM and Huntsville, Alabama connections. Let's just not talk about it, m'kay? And then of course it is his rocket that is the only one available to put a satellite in orbit in the fall of 1957, or, as it happens, the winter of 1958, because the Navy's Vanguard program had ended up even further behind, somehow.
The upshot here is that the United States had three separate space/intercontinental programs ongoing in 1957/8, that all three of them were behind, and, as per the topic of this week's appendix, the Air Force's rocket was, to coin a Fifties-style neologism, a ballissile, specifically the SM-65 Atlas.

"Power To Cheap To Meter:" A Technical Appendix to Postblogging Technology, August 1955
![]() |
| The now-closed Dounreay fast breeder reactor in Caithness, Scotland |
Anyway, the experience of postblogging technology is always weird because it's the most direct and easiest way to encounter that classic historian's disconnect between the popular history that solidifies around an event, and the actual events. Guys! There was no Sputnik surprise! Everyone knew that the Americans and Soviets were going to launch satellites during the (eighteen month) International Geophysical Year and that the Soviets were talking about an earlier launch date than the Americans. I don't think I've come close to unpacking why it was said to be a surprise, but we've got two years to go on that one.
"Power too cheap to meter" is a quote from Lewis Strauss, speaking in 1954 to the National Association of Science Writers. Strauss has not been well treated by history, and I am not here to be contrarian, but he went on to offer water as an example of something that progress had made "too cheap to meter," and from that perspective it's at least a plausible bit of prediction. Had he chosen to talk about about long-distance telephony, he would come across a regular prophet! For that matter, he turns out to have been a lot more wrong about predicting extended lifespans. Unmetered power turns out to be further away than ever, but at least there's a road to this outcome. The Wiki goes on to explain that the "statement was contentious from the start . . ." pointing out that, even in 1954, the AEC was not boundlessly optimistic about the future costs of nuclear power, and that one researcher found "dozens of statements" to that effect. Strauss' son seems to have hijacked the conversation by proposing that Strauss was talking about fusion power, something that we've seen as problematic at the Geneva Atomics for Peace conference, where Strauss comes out with a more typical blunder, trying to keep American fusion research secret for no particular reason. But, of course, "power to cheap to meter" comes out of Geneva very directly in a way that has nothing to do with either conventional atomic power or fusion: Breeder reactors.

Satellites, Satelloons, and Golf: A Technological Prologue to Postblogging Technology, August 1955
| Source: https://www.original-political-cartoon.com/cartoon-gallery/buy/caption-displayed/385/ |
Historians' views of the Eisenhower Administration have . . . evolved. Better known as a late-era Modesty Blaise-relief cartoonist, Neville Colvin, a newly-arrived refugee from the "stifling atmosphere of Fifties New Zealand," captures the contemporary view of Eisenhower for Fleet Street. Uninterested, or even lazy, but with a lashing of malice barely under control. This is a thoroughly worthless First Executive. While the Britain, having given the world a senile dotard and a meth-head in succession, is not the country to point fingers, there's a sense that the United States has lost eight years. In contrast, writing in 1986, Robert J. MacMahon reviewed a decade of "Eisenhower revisionism" as being most successful in overturning "the traditional interpretation of an inept, bewildered President overwhelmed by his formidable secretary of state." Although "it can be fairly said that the majority of case studies have not sustained Eisenhower revisionism," because the revisionists "have elevated process over policy," we can at least agreed that foreign policy, at least, was "orderly and rational." I'm a bit surprised that MacMahon never gets into the President's health, but, anyway, about that---
Satellites.

War Balloons and Satelloons! A Technical Appendix to Postblogging Technology, July 1955
That's "Fu-Go," not "Fugu." Those wacky Japanese! So I hope that the readers have been as struck as I have been by The Periscope's ongoing obsession with balloons. Since the column has been talking up balloon-carried H-bombs as an Air Force project, this isn't necessarily all about the Skyhook programme, but Periscope is definitely on that case, too, with its talk of the programme setting an altitude record soon, and reaching 250 miles altitude, which is why you should never have a third martini when you're having lunch with your sources. I mean, there was a time when cementing your name in history as the dumbest nepo baby ever was a potential achievement, but nowadays we've got Larry Summers. In conclusion, why even try?

The Le Mans Disaster: A Technical Appendix to Postblogging Technology, May 1955
| This is a snip: Source is https://www.mike-hawthorn.org.uk/lemans2.html Discussion below. |
One thing that holds from that draft, which, I reiterate, you will never see because it was so dumb, is that it continues a theme from these posts, which is that people were pretty reckless back in 1955. This week's post could just have easily have been about the Salk vaccine contamination disaster, which still has me shaking my head as the contemporary press brings me further abreast of it. (The modern view, such as it is, being very much of the "Look forward, never back" variety.) On the other hand, there's a lot of America bashing around, here so a bit of a palate cleanser in the form of a look at an all-European fiasco is welcome! Even if I somehow get back to the America-bashing at the end. Sheesh.
What the heck, though, it's been a week, and I dearly hope that anyone reading this in a year's time has no idea what I'm talking about.

Draining Lake Copais: A Technical Appendix to Postblogging Technology, May 1955, I With Bonus LBA Collapse
Edit: A bit quick with this one.
Responding to a 29 November, 1952 article in The Economist putting forward "rather pessimistic predictions" about the future of the Basin after the departure of English managers, writing in a letter published in the 30 April 1955 issue, P. X. Levandis, the Greek Agricultural Minister was pleased to refute those predictions by citing high production per hectare. I missed this letter because I don't do the end-of-month issues of The Economist unless I've screwed up my withdrawal requests, which never happens, practically. Well, hardly ever.
I did not miss, and mentioned in the postblogging, the response of the Liquidator of the Lake Copais Corporation, F, W. Willis. Willis refutes the claim of increased productivity of wheat and cotton by showing that Levandis is using misleading figures, specifically only those of the freeholding farmers. When land held by the company, or now the Greek government, and run as largescale farms are included, there is no trend line. Without going back three years to find out just how pessimistic The Economist was being, consider it not refuted. On the other hand, there's evidently a whole history here of the people who actually farmed the land, and something of an elephant in the room in terms of what was farmed. Wheat and cotton are cash crops, and in particular the great cash crops of third-quarter Nineteenth Century agricultural expansion that gave us bonanza farms in the Americas and Australia and more complicated booms in the Old World. (For example, the "salinisation crisis due to irrigation/irrigation failure due to rampaging Mongols" story about Iraqi agriculture derives from abandoning barley for wheat in this period.)
Wheat and cotton are, as these things go, extensive crops, not traditionally the ones you grow on expensively reclaimed land. The Greeks eat rice and make linen, right? Given the emphasis on the landholders, one wonders exactly how much consultation there was with the locals who might have been using the Lake for traditional purposes like retting flax for weaving prior to the beginning of excavation and pumping.

Philco, Roger: A Technical Appendix to Postblogging Technology, April 1955
Not to be indelicate, but what the fuck happened?
As Philco ("Philadelphia Electric Company") launches the marketing campaign for its Transac computer line in 1955, it was celebrating twenty-five straight years of leading the American radio industry by volume of sales. Curtiss-Wright, named for Glenn L. Curtiss and Orville Wright, started as a patent pool holding virtual monopoly rights over American aviation, from which foundations came a major aircraft company and one pole of the virtual duopoly of American aircraft engine manufacturing. The Douglas DC-7, currently winning the sales that will, it turns out, end the British airliner resurgence, is flying with four Wright R-3350 Turbo-Compounds, essentially demonstrating that, as far as long distance commercial flying goes in the mid-Fifties, there is basically just one alternative.
Today? There's still a Curtiss-Wright, sort of, but no engines, no computers. And it took barely five years.

Pentomic: A Technical But Actually Sociological Appendix to Postblogging Technology, April 1955, I
So Braddock's Expedition is a bit confusing because American historians all talk about his two regiments, and military historians of the Nineteenth Century know that's about ten thousand men, which is a huge force by the standards of Eighteenth Century colonial warfare, and meanwhile military historians of the Eighteenth Century are, like, "what's a regiment?" It's not inaccurate, in that regiments did exist in the Eighteenth Century as political, financial and administrative elements, and the particular two battalions of the Irish Establishment that came out with Braddock belonged to single battalion regiments. American military historians are probably informed by reading about the Civil War, where, as was often the case in that era, it was found necessary to insert an additional tier in the command structure of the Age of Reason. That is, in 1755 there were so many companies per battalion, so many battalions per brigade, so many brigades per [insert tedious historiographical discussion here] division. In 1860, armies with lots of conscripts found that this wasn't enough supervision and turned the regiment into an organisational level between battalion and brigade. Conscripts, and their ROTC officers, just need more attention from more headquarters because they can't be trusted to know what they're doing on their own.
The aftermath of Braddock's Defeat is also confusing, because, we are told, a wave of Indian attacks caused settlers to abandon frontier settlements and flee eastward, with a strong subtext of a racial war against the Westward Drive, Frontier Spirit, and Manifest Destiny. And we are not told wrong, except that, with the exception of three extraordinary attacks, the trouble took place in what was then Pennsylvania's Northumberland County, now Monroe and Pike counties, or, in Eighteenth Century usage, the "Minisink Valley," which is not a valley at all, but the region north of the Delaware Water Gap cupped by the Poconos Mountains that was shared between Pennsylvania, New York, and West Jersey, as it still was. The attacks were absolutely Indian attacks, made specifically by the followers of Teedyuscung, probably a grandson of Tamanend and, if my tinfoil hat isn't fitting too tight, William Penn, with an internally Pennsylvanian objective, which was why the raiders spared New York and New Jersey, and why the raids were probably actually a pogrom, which is why almost all the attacks killed the patriarchs of the settlements raided, and probably why there's a slightly panicked subtext to Ben Franklin's reports about the refugees gathering in New Jersey. Because if they weren't leading members of these families, they were probably mostly enslaved. This was a Pennsylvanian civil war. The racial component isn't "Scotch-Irish" versus Indians, but rather a peasant's revolt.
No wonder, then, that the Pennsylvanian Assembly settled quickly in the 1758 Treaty of Easton. But before that could happen, and just to drag this preamble around to relevance, Henri Bouquet, the Swiss Protestant (that is, Francophone) favourite of the Duke of Cumberland, had arrived in Philadelphia and there formed, not to get all genealogical, one of the ancestral units of the King's Royal Rifle Corps, most easily searched, I suspect, as the 60th (American) Rifles. Per the source most recently consulted --probably Wikipedia, but I forget-- this was formed from immigrant German workingmen. Wikipedia does not note that in 1756 the Germans who were immigrating to Philadelphia were mostly coming from German Flats, far up the Mohawk, where a German-speaking community had been growing by ethnogenesis from 1719. With regards to the demographic raw material, this can only have been the free Blacks who could not exist as such in the Eighteenth Century American cosmic order. This probably explains why Bouquet didn't need to subject his riflemen to some specialised training regime to turn them into another of the mid-Eighteenth Century's many ethnically-recruited special forces.Which is usually a bit of an anachronism in that the European units that trace their tradition to the Eighteenth Century special forces have all been long since de-specialed, pipe bands apart.
The American ranger tradition is an exception, and one that, I suggest, is rooted in race, not the primeval (hah!) forest of the American frontier.
