Confounded Progress : a book about "Penicillins, Ancient and Modern"

A book about WWII's warring penicillins, Ancient and Modern


The genes that make penicillin reside today inside members of the comparatively recent fungus family, but these genes actually began their existence inside bacteria, those tiny creatures ancient beyond all time.

Ancient they might well be and simple too, but these microbes somehow do a very, very, very efficient job as chemists.

Again and again they are found to be very rapidly making complicated molecules, in the correct stereo image, and without impurities, at normal temperatures and pressures, without need for heavily built reactor vessels or expensive reagents.

All this not unnaturally makes human chemists jealous and resentful - never more than in the late unlamented Era of Progress, when human chemists were at the very top of the food chain and small stupid microbes were supposed to foot the very bottom.

Together, top chemists and bottom microbes were to support the whole Progressive Era 'scientific/natural' hierarchy that allowed whites to repress blacks, adults children, men women, the healthy the cripples.

All predicated on the claim that Life formed one seamless and vertical 'Great Ladder of Progress'.

A ladder stretching from the stupidest,oldest and smallest to the newest, biggest, smartest white human civilizations at the very top.

So the news that such a very great boon to humanity like penicillin could only be made by the stupidest and couldn't be made at all by the very smartest, threatened this whole tissue of lies.

Which is why that for twenty years (1928-1948) the 'smartest chemists in the universe' sought, in war as in peace, to make an improved modern version of the fungus's ancient penicillin.

They even placed their psychological need to shore up the idea of Progress before the medical needs of millions of dying patients, crying out in vain for any sort of penicillin --- be it ancient or modern .

So much so that when the last projects to try and produce man-made synthetic penicillin finally failed, so, to a large extent, did the very idea of Progress...

Modernity failed (and eventually faded) when synthetic penicillin failed

Forget what books and movies, your teachers, professors, parents and grandparents all tell you about WWII's "hands across the water" holy war against the utterly evil Nazi values:
because no nation in WWII ever went to war against the Axis unless and until they were first directly attacked by the Axis : on the factual evidence, they warred against the Axis solely in self defence.
Except, of course, for the empires of England and France --but :
if the peoples of these two superpowers still claim that they went to war solely on behalf of the small victims of the Axis, their subsequent actions would hardly prove that assertion -- as generations of Polish (and Jewish) academics are rightly eager to point out.
The problem was that the values of the Axis were but an extreme form - but still fully recognizable - of the same values of Modernity espoused by the middle class of every 'modern' nation on earth in that era .

A world wide middle class culture as largely indifferent to the lynching of Blacks in Georgia USA as to the lynching of Jews in Georgia USSR.

Those values were somewhat under attack during the Great Depression period.

But recent research has revealed that the WWII years were unexpectedly a time when protest against such un-charitable values was actually muted - not heightened - by the military conflict against the nations applying those values in their most extreme forms.

WWII's ideological war that didn't parallel the military war


But I think there was still one all-out ideological battle during WWII, one that ended in the defeat of the Modernity values that fuelled the Axis and led in time to our open commensality led era of post-Modernity diversity and tolerance.

That battle was over who/what would provide the bulk of the Allies' D-Day penicillin.

Synthetic Penicillin to be the Poster Boy of WWII's Terrible Simplicities


On one side were hundreds of the smartest chemists in the universe , assembled by the Allied scientific establishment which believed that man-made synthetic penicillin simply had to be better and cheaper than anything stupid Nature could come up with.

On the other side, an invisibly small team in a backwater ward at Columbia Presbyterian hospital whose leader Martin Henry Dawson said 'don't count the old and the slow and small microbes out so quickly - they just might be able to do it better and cheaper and quicker'.

A lot was at stake : for all of the towering edifice of Modernity was actually sustained on a single slender stock of pure conjecture.

That conjecture was that the biggest, most swiftly advancing, most complex human civilizations at the cutting edge of Life had to inevitably be smarter that the oldest,slowest, smallest microbes that began Life three billion years earlier -in each and every area.

Reductionism was the ideology of Modernity.


It saw the basic bricks of life or reality as being simple and simple minded .

So complexity/intelligence had to grow out of these bricks being assembled into ever bigger entities in a single straight upward line : complexity growing steadily upwards from a single electron to the Hoover Dam, from a single penicillium 'yeast' cell to a tenured chemist with a PhD.

It was true that there was an infection-filled war on and any sort of life-saving penicillin was greatly needed - now !

But the Allied scientific elite would unconsciously rather lose the military war to their (fellow modernist) Nazi opponents than lose the much more important ideological war to the despised slime cells on the question as to who could better make the vital lifesaver : sophisticated Man or stupid microbe.

Feel free to substitute Negro, Jew, Oriental, aboriginal, woman, homosexual, cripple for microbe to better appreciate their deepest physic fears.

But in the end, by D-Day 1944 and beyond, all those genius-level chemists had totally failed - and have still failed, seventy five years on : a single yeast penicillium cell still makes penicillin cheaper and better than by any human synthetic method.

And from that same basic wartime penicillin G, still made in the tens and tens of thousands of tons today by those incredibly tiny yeast cells, we humans create almost all the infection fighting antibiotics we have today.

If the human small and the slow and the old and weak have more respect today than they did in 1940 - and they do, much much more - it won't hurt to thank the first ones who gained that reluctant respect : the penicillium yeasts cells ...

Natural penicillin the Strawberry Roan : there ain't no chemist here all alive that can stay with that mold when it makes that... high dive"

Chemists versus the fungal Strawberry Roan


To the Big Scientists of the Modern Age , natural penicillin from the penicillium mold was like an old moth-eaten cayuse , an old strawberry roan , a has been and a never was .

They saw it as a living being easily broken at the chemical wheel - requiring only a little heat and pressure to make it reveal all of its secrets.

Then the chemists could patent improved analogues of natural penicillin and thus corner the financial market on this precious lifesaver.

But as Montana Slim (Wilf Carter) might have sung it - "There ain't no chemist here all alive that can stay with that mold when it makes that... high dive."

Eighty seven years after chemists first set to work to break the penicillium mold , it still rides the range free and unpatented.

"A true micro bucking bronco that's never been rid, though there's many a chemist that claims that he did...."

Chemistry PhD = Hubris ?

As penicillium mold spores drift about through the air, the fortunate ones land on a suitably moist food supply.

The spores almost need the moisture more than the food , as they can feed on almost any organic matter.

But when they get stressed, usually when the food supply runs low , they may respond by producing the antibiotics we rather loosely call by the single word 'penicillin' , to keep at bay bacterial competitors for that same food.

Note I said antibiotics in the plural, because, depending on the particular food source at hand, each penicillin produced might be in fact ever so slightly different.

Technically, the key part of the penicillin molecule - the famous strained beta lactam ring - must always be there , for it to work as a antibiotic .

But the extra bit on the side of that key component - the side chain - can vary widely and will tend to produce various kinds and strengths of antibiotics.

Many of them offer different - useful - qualities - from the original penicillin (type G).

Now, in Nature , all these marvellous variants are mere happy accidents induced by the chance of varying wind currents and drifting spores.

In the Lab, biologists and chemists feed the penicillium spores all sorts of extra food treats , (fancied up ,the technical word for these humble food supplements is precursors) hoping to see a useful variant emerge.

When the new improved variants do emerge , the chemists tend to glorify this 'brute force' approach to the discovery of new chemicals by daring to call the results "semi-synthetic" penicillin.

But this just hubris and hooey.

It is merely a way for human chemists - who tried and failed to make penicillin from scratch* like the tiny mold spores so readilyand so easily did - to regain some lost luster for their profession.

(*To chemists , this is their holy grail of  "total synthesis".)

Because it is really no different than the ancient practise of farmers trying out plants on differing soil mixtures and cultivation techniques and running with the methods that gave the best yields.

The chemists, rather like the British , lost really big in WWII.

Partly to physics (the A-Bomb) and partly to biology (natural penicillin triumphing over the chemists' failure to make synthetic penicillin) .

And like the British, they've been trying to re-write the history of WWII ever since ....

Penicillin : a bunch of biologists who put all their faith in chemistry vs two chemists who put all their faith in biology

In the Alice Through the Looking Glass world of wartime penicillin it should hardly be surprising that about the only strong supporters of natural ,biological, penicillin in the upper echelons of the overall enterprise were two professional chemists : Larry Elder of the American Office for Production Research and Development (the OPRD) and Harry Jephcott of the British drug company, Glaxo.

Or that the group most strongly bewitched by the thought of synthetic penicillin were a bunch of medical doctors with Howard Florey and Alexander Fleming leading the charge (with the OSRD and MRC close behind): the sort of scientists who might have been thought would normally occupy a place at the biological end of  hard science.....

Would penicillin have been available for patients in 1930, if Fleming had produced his '29 paper - and then died ?

If only pneumonia had killed Alec, not John....
Imagine - if you will - that you're at a medical meeting - one of hundreds and hundreds that Alexander Fleming routinely attended between the Fall of 1928 and the Fall of 1942 and you happen to overhear Fleming regaling a small audience in the corridor about his 'wonderful' penicillin.


It is, he says (translated into today's medical terminology) a wide spectrum totally non-toxic anti-bacterial agent , the only one he as ever seen that doesn't harm the natural healing powers of the body's blood.

It is, Fleming says with great force , simply a great lab clearing agent for vaccine studies and potentially a useful antiseptic...

....And ? AND ?!  You wait for the other shoe to drop, somewhat impatiently : how is it as a systemic, for saving those dying from bacterial infections ?

Oh that, says Fleming indifferently , its useless for that.

And, he adds brutally honestly , as an antiseptic it is slow acting and is so unstable that it will only be useful if the chemists can synthesize it - but they haven't so far.

For fourteen years , I believe only one man stood between penicillin the potential life-saver for millions and penicillin the actual life saver for millions and that man was - unfortunately - Alexander Fleming.

The history of penicillin might have been quite different if only he and not his brother John had died of the pneumonia that Fleming's 1928 imperfect penicillin would have cured.

I can not believe that Fleming could offer such frequent public build-ups of his wonderful penicillin without someone in the audience venturing : well how do you rate its life-saving systemic qualities then ?

Fleming in his honest (but incorrect) way , would have had to say in public what he deliberately omitted from his published articles : 'as a systemic, I believe that penicillin is useless'.

This - more than anything someone else did or didn't do - dammed penicillin to wander useless in the desert for 15 years : its own discoverer damning it with the very faintest of praise ....

Why My Urgency ?

My photo

Histories of WWII all start with the presumption that it was a war raged between humans and human ideologies, with Nature’s climate and geography as side issues easily surmounted.My blog, on the contrary will only accept that it was conflict between humans and their ideology that STARTED the war but that it was the barriers thrown up by Mother Nature (geography & climate) that turned it into a war that lasted between 6 to 15 years and expanded to thoroughly involve all the world’s oceans and continents. High Modernity may have started the war convinced that Nature had been conquered and was about to be soon replaced by human Synthetic Autarky and that only human Tiger tanks and human Typhoon planes were to be feared. But by the end, more and more people had lost their naive faith in Scientism and were beginning to accept that humanity was thoroughly entangled with both the Nature of plants, animals & microbes as well as the Nature of so called “lesser” humanity. By 1965, the world was definitely entering the Age of Entanglement. Billions still believed - at least in part -with the promises of High Modernity but intellectually & emotionally, it was no longer dominant...
