|An article in Harper's Magazine written just over a year after the end of the war lists just a few of the
technological marvels US and British Troops found and stole, along with all German patents. These
inventions and the technology was farmed out to special interests, mostly in the USA.
Walker, Lester C. October, 1946 War Secrets by the Thousands (P. 329) Harper's Magazine
|What did we find? You'd like some outstanding examples from the war secrets collection?
The head of the communications unit of Technical Industrial Intelligence Branch opened his desk
drawer and took out the tiniest vacuum tube I had ever seen. It was about half thumb-size.
"Notice it is heavy porcelain – not glass – and thus virtually indestructible. It is a thousand watt – one-
tenth the size of similar American tube. Today our manufacturers know the secret of making it....
And here's something...."
He pulled some brown, papery-looking ribbon off a spool. It was a quarter-inch wide, with a dull and
a shiny side.
"That's Magnetophone tape," he said. "It's plastic, metallized on one side with iron oxide. In
Germany that supplanted phonograph recordings. A day's Radio program can be magnetized on one
reel. You can demagnetize it, wipe it off and put a new program on at any time. No needle; so
absolutely no noise or record wear. An hour-long reel costs fifty cents." He showed me then what
had been two of the most closely-guarded technical secrets of the war: the infra-red device which the
Germans invented for seeing at night, and the remarkable diminutive generator which operated it.
German cars could drive at any speed in a total blackout, seeing objects clear as day two hundred
meters ahead. Tanks with this device could spot targets two miles away. As a sniper scope it enabled
German riflemen to pick off a man in total blackness.
There was a sighting tube, and a selenium screen out front. The screen caught the incoming infra-red
light, which drove electrons from the selenium along the tube to another screen which was electrically
charged and fluorescent. A visible image appeared on this screen. Its clearness and its accuracy for
aiming purposes were phenomenal. Inside the tube, distortion of the stream of electrons by the
earth's magnetism was even allowed for!
The diminutive generator – five inches across – stepped up current from an ordinary flashlight
battery to 15,000 volts. It had a walnut-sized motor which spun a rotor at 10,000 rpm – so fast that
originally it had destroyed all lubricants with the great amount of ozone it produced. The Germans
had developed a new grease: chlorinated paraffin oil. The generator then ran 3,000 hours!
A canvas bag on the sniper's back housed the device. His rifle had two triggers. He pressed one for a
few seconds to operate the generator and the scope.. Then the other to kill his man in the dark. "That
captured secret," my guide declared, "we first used at Okinawa – to the bewilderment of the Japs."
We got, in addition, among these prize secrets, the technique and the machine for making the world's
most remarkable electric condenser. Millions of condensers are essential to the radio and radar
industry. Our condensers were always made of metal foil. This one is made of paper, coated with
1/250,000 of an inch of vaporized zinc. Forty per cent smaller, twenty per cent cheaper than our
condensers, it is also self-healing. That is, if a breakdown occurs (like a fuse blowing out), the zinc
film evaporates, the paper immediately insulates, and the condenser is right again. It keeps on
working through multiple breakdowns – at fifty per cent higher voltage than our condensers! To most
American radio experts this is magic, double-distilled.
Mica was another thing. None is mined in Germany, so during the war our Signal Corps was
mystified. Where was Germany getting it?
One, day certain piece of mica was handed to one of our experts in the U.S. Bureau of Mines for
analysis and opinion. "Natural mica," he reported, "and no impurities."
But the mica was synthetic. The Kaiser Wilhelm Institute for Silicate Research had discovered how
to make it and – something which had always eluded scientists – in large sheets.
We know now, thanks to FIAT teams, that ingredients of natural mica were melted in crucibles of
carbon capable of taking 2,350 degrees of heat, and then – this was the real secret – cooled in a
special way. Complete absence of vibration was the first essential. Then two forces directly
perpendicular to each other were applied. One, vertically, was a controlled gradient of temperature in
the cooling. At right angles to this, horizontally, was introduced a magnetic field. This forced the
formation of the crystals in large laminated sheets on that plane.
"You see this . . ." the head of Communications Unit, TIIB, said to me. It was metal, and looked like
a complicated doll's house with the roof off. "It is the chassis or frame, for a radio. To make the
same thing, Americans would machine cut, hollow, shape, fit – a dozen different processes. This is
done on a press in one operation. It is called the 'cold extrusion' process. We do it with some soft,
splattery metals. But by this process the Germans do it with cold steel! Thousands of parts now
made as castings or drop forgings or from malleable iron can now be made this way. The production
speed increase is a little matter of one thousand per cent."
This one war secret alone, many American steel men believe, will revolutionize dozens of our metal
In textiles the war secrets collection has produced so many revelations that American textile men are
a little dizzy. There is a German rayon-weaving machine, discovered a year ago by the American
'Knitting Machine' Team, which increases production in relation to floor space by one hundred and
fifty percent. Their "Links-Links" loom produces a ladderless, run-proof hosiery. New German
needle-making machinery, it is thought will revolutionize that business in both the United Kingdom
and the United States. There is a German method for pulling the wool from sheepskins without
injury to hide or fiber, by use of an enzyme. Formerly the "puller" – a trade secret – was made from
animal pancreas from American packing houses. During the war the Nazis made it from a mold
called aspergil paraciticus, which they seeded in bran. It results not only in better wool, but in ten per
cent greater yield.
Another discovery was a way to put a crimp in viscose rayon fibers which gives them the
appearance, warmth, wear resistance, and reaction-to-dyes of wool. The secret here, our
investigators found, was the addition to the cellulose of twenty-five per cent fish protein.
But of all the industrial secrets, perhaps, the biggest windfall came from the laboratories and plants of
the great German cartel, I. G. Farbenindustrie. Never before, it is claimed, was there such a store-
house of secret information. It covers liquid and solid fuels, metallurgy, synthetic rubber, textiles,
chemicals, plastics, drugs, dyes. One American dye authority declares:
"It includes the production know-how and the secret formulas for over fifty thousand dyes. Many of
them are faster and better than ours. Many are colors we were never able to make. The American
dye industry will be advanced at least ten years."
IN MATTERS of food, medicine, and branches of the military art the finds of the search teams were
no less impressive. And in aeronautics and guided missiles they proved to be downright alarming.
One of the food secrets the Nazis had discovered was a way to sterilize fruit juices without heat. The
juice was filtered, then cooled, then carbonated and stored under eight atmospheres of carbon-
dioxide pressure. Later the carbon-dioxide was removed; the juice passed through another filter –
which, this time, germ-proofed it – and then was bottled. Some thing, perhaps, for American canners
to think about.
Milk pasteurization by ultra-violet light has always failed in other countries, but the Germans had
found how to do it by using light tubes of great length, and simultaneously how to enrich the milk
with vitamin D.
At a plant in Kiel, British searchers of the Joint Intelligence Objectives Committee found that cheese
was being made – "good quality Hollander and Tilitser" – by a new method at unheard-of speed.
"Eighty minutes from the renneting to the hooping of the curd," report the investigators. The cheese
industry around the world had never been able to equal that.
Butter (in a creamery near Hamburg) was being produced by something long wished for by American
butter makers: a continuous butter making machine. An invention of dairy equipment manufacturers
in Stuttgart, it took up less space than American churns and turned out fifteen hundred pounds an
hour. The machine was promptly shipped to this country to be tested by the American Butter
Among other food innovations was a German way of making yeast in almost limitless quantities. The
waste sulfite liquor from the beechwood used to manufacture cellulose was treated with an organism
known to bacteriologists as candida arborea at temperatures higher than ever used in yeast
manufacture before. The finished product served as both animal and human food. Its caloric value is
four times that of lean meat, and it contains twice as much protein.
The Germans also had developed new methods of preserving food by plastics and new, advanced
refrigeration techniques. Refrigeration and air-conditioning on German U-boats had become so
efficient that the submarines could travel from Germany to the Pacific, operate there for two months,
and then return to Germany without having to take on fresh water for the crew. A secret plastics
mixture (among its ingredients were polyvinyl acetate, chalk, and talc) was used to coat bread and
cheese. A loaf fresh from the oven was dipped, dried, redipped, then heated half an hour at 285
degrees. It would be unspoiled and good to eat eight months later.
"As for medical secrets in this collection," one Army-surgeon has remarked, "some of them will save
American medicine years of research; some of them are revolutionary – like, for instance, the
German technique for treatment after prolonged and usually fatal exposure to cold." This discovery –
revealed to us by Major Alexander's search already mentioned – reversed everything medical science
thought about the subject. In every one of the dread experiments the subjects were most successfully
revived, both temporarily and permanently, by immediate immersion in hot water. In two cases of
complete standstill of heart and cessation of respiration, a hot bath at 122 degrees brought both
subjects back to life. Before our war with Japan ended, this method was adopted as the treatment for
use by all American Air-Sea Rescue Services, and it is generally accepted by medicine. today.
German medical researchers had discovered a way to produce synthetic blood plasma. Called capain,
it was made on a commercial scale and equaled natural plasma in results. Another discovery was
periston, a substitute for the blood liquid. An oxidation production of adrenalin (adrenichrome) was
produced in quantity successfully only by the Nazis and was used with good results in combating
high blood pressure (of which 750,000 persons die annually in the United States). Today we have the
secret of manufacture and considerable of the supply.
Likewise of great importance medically were certain researches by Dr. Boris Rojewsky of the Kaiser
Wilhelm Institute of Biophysics at Frankfurt. These were on the ionization of air as related to health.
Positively ionized air was discovered to have deleterious effects upon human well-being, and to
account for the discomfort and depression felt at times when the barometer is falling. In many
persons, it was found, its presence brought on asthma, hay fever, and nervous tension. It raised high
blood pressure, sometimes to the danger point. It would bring on the symptoms common in mountain
sickness – labored and rapid breathing, dizziness, fatigue, sleepiness.
Negatively ionized air, however, did all the opposite. It was exhilarating, creating a feeling of high
spirits and well-being. Mental depression was wiped out by it. In pathological cases it steadied
breathing, reduced high blood pressure, was a check on allergies and asthma. The importance of its
presence wherever human beings live, work, or recuperate from illness may some day make its
production one of the major functions of air conditioning.
But of highest significance for the future were the Nazi secrets in aviation and in various types of
"The V-2 rocket, which bombed London," an Army Air Force publication reports, "was just a toy
compared to what the Germans had up their sleeve."
When the war ended, we now know, they had 138 types of guided missiles in various stages of
production or development, using every known kind of remote control and fuse: radio, radar, wire,
continuous wave, acoustics, infra-red, light beams, and magnetics, to name some; and for power, all
methods of jet propulsion for either subsonic or supersonic speeds. Jet propulsion had even been
applied to helicopter flight. The fuel was piped to combustion chambers at the rotor blade tips, where
it exploded, whirling the blades around like a lawn sprinkler or pinwheel. As for rocket propulsion,
their A-4 rocket, which was just getting into large scale production when the war ended, was forty-six
feet long, weighed over 24,000 pounds, and traveled 230 miles. It rose sixty miles above the earth
and had a maximum speed of 3,735 miles an hour – three times that of the earth's rotation at the
equator. The secret of its supersonic speed, we know today, lay in its rocket motor which used liquid
oxygen and alcohol for fuel. It was either radio controlled or self-guided to its target by gyroscopic
means. Since its speed was supersonic, it could not be heard before it struck.
Another German rocket which was coming along was the A-9. This was bigger still – 29,000 pounds
– and had wings which gave it a flying range of 3,000 miles. It was manufactured at the famous
Peenemunde army experiment station and achieved the unbelievable speed of 5,870 miles an hour.
A long range rocket-motored bomber which, the war documents indicate, was never completed
merely because of the war's quick ending, would have been capable of flight from Germany to New
York in forty minutes. Pilot-guided from a pressurized cabin, it would have flown at an altitude of
154 miles. Launching was to be by catapult at 500 miles an hour, and the ship would rise to its
maximum altitude in as short a time as four minutes. There, fuel exhausted, it would glide through
the outer atmosphere, bearing down on its target. With one hundred bombers of this type the
Germans hoped to destroy any city on earth in a few days' operations.
Little wonder, then, that today Army Air Force experts declare publicly that in rocket power and
guided missiles the Nazis were ahead of us by at least ten years.
The Germans even had devices ready which would take care of pilots forced to leave supersonic
planes in flight. Normally a pilot who stuck his head out at such speeds would have it shorn off. His
parachute on opening would burst in space. To prevent these calamitous happenings an ejector seat
had been invented which flung the pilot clear instantaneously. His chute was already burst, that is,
made of latticed ribbons which checked his fall only after the down-drag of his weight began to close
A Nazi variation of the guided air missile was a torpedo for underwater work which went unerringly
to its mark, drawn by the propeller sound of the victim ship from as far away as ten miles. This
missile swam thirty feet below the water, at forty miles an hour, and left no wake. When directly
under its target, it exploded.
All such revelations naturally raise the question: was Germany so far advanced in air, rocket, and
missile research that, given a little more time, she might have won the war? Her war secrets, as now
disclosed, would seem to indicate that possibility. And the Deputy Commanding General of Army Air
Forces Intelligence, Air Technical Service Command, has told the Society of Aeronautical Engineers
within the past few months:
"The Germans were preparing rocket surprises for the whole world in general and England in
particular which would have, it is believed, changed the course of the war if the invasion had been
postponed for so short a time as half a year."
For the release and dissemination of all these one-time secrets the Office of the Publication Board
was established by an order of President Truman within ten days after Japan surrendered. The order
directed that not only enemy war secrets should be published, but also (with some exceptions) all
American secrets, scientific and technical, of all government war boards. (The Office of Scientific
Research and Development, the National Research Council, and other such.) And thereby was
created what is being termed now the biggest publishing problem a government agency ever had to
For the war secrets, which conventionally used to be counted in scores, will run to three-quarters of a
million separate documentary items (two-thirds of them on aeronautics) and will require several years
and several hundreds of people to screen and prepare them for wide public use.
Today translators and abstracters of the Office of Technical Services, successor to the OPB, are
processing them at the rate of about a thousand a week. Indexing and cataloguing the part of the
collection which will be permanently kept may require more than two millions cards; and at Wright
Field the task is so complicated that electric punch-card machine are to be installed. A whole new
glossary of German-English terms has had to be compiled – something like forty thousand words on
new technical and scientific items.
With so many documents, it has, of course, been impossible because of time and money limitations
to reprint or reproduce more than a very few. To tell the public what is available, therefore, the OTS
issues a bibliography weekly. This contains the newest war secrets information as released – with
titles, prices of copies currently available or to be made up, and an abstract of contents.
The original document, or the microfilm copy, is then generally sent to the Library of Congress,
which is now the greatest depository. To make them more easily accessible to the public, the Library
sends copies, when enough are available, to about 125 so-called "depository" libraries throughout the
And is the public doing anything with these one-time war secrets? It is – it is eating them up. As
many as twenty thousand orders have been filled in a month, and the order rate is now a thousand
items a day. Scientists and engineers declare that the information is "cutting years from the time we
would devote to problems already scientifically investigated." And American business men ...! A run
through the Publication Board's letters file shows the following;
The Bendix Company in South Bend, Indiana, writes for a German patent on the record player
changer "with records stacked above the turntable." Pillsbury Mills wants to have what is available on
German flour and bread production methods. Kendall Manufacturing Company ("Soapine") wants
insect repellent compounds. Pioneer Hi-Bred Corn Company, Iowa, asks about "interrogation of
research workers at the agricultural high school at Hohenheim." Pacific Mills requests I. G.
Farbenindustrie's water-repellent, crease-resistant finish for spun rayon. The Polaroid Company
would like something on "the status of exploitation of photography and optics in Germany." (There
are, incidentally, ten to twenty thousand German patents yet to be screened.)
The most insatiable customer is Amtorg, the Soviet Union's foreign trade organization. One of its
representatives walked into the Publication Board office with the bibliography in hand and said, "I
want copies of everything." The Russians sent one order in May for $5,594.00 worth – two thousand
separate war secrets reports. In general, they buy every report issued. Americans, too, think there is
extraordinarily good prospecting in the war secrets lode. Company executives practically park on the
OTS's front doorstep, wanting to be first to get hold of a particular report on publication. Some
information is so valuable that to get it a single day ahead of a competitor, may be worth thousands
of dollars. But the OTS takes elaborate precautions to be sure that no report is ever available to
anyone before general public release.
After a certain American aircraft company had ordered a particular captured war document, it was
queried as to whether the information therein had made it or saved it any money. The cost of the
report had been a few dollars. The company answered: "Yea – at least a hundred thousand dollars."
A research head of another business firm took notes for three hours in the OTS offices one day.
"Thanks very much," he said, as he stood to go, "the notes from these documents are worth at least
half a million dollars to my company."
And after seeing the complete report the German synthetic fiber industry, one American
"This report would be worth twenty million dollars to my company if it could have it exclusively."
Of course you, and anybody else, can now have it, and lots of other once secret information, for a
few dollars. All the war secrets, as released, are completely in the public domain.
