Prioré, the French "Rife"

Antoine Prioré - The French "Rife"

The Story of Antoine Prioré

Over a period of 25 years, between 1950 and 1975, he is said to have cured all incurable cancers in animals, from mice to dogs with a unique electrotherapy device he invented. He hoped to do no less than to revolutionize the treatment of cancer.

Many tests on man were successful, with the decrease and sometimes with the disappearance of the tumour although the adjustments were very delicate and some modifications led to a worsening of the cancer.

The majority of these treatments, conducted in collaboration with the Faculty of Medicine,  hospitals in Bordeaux and sometimes with the Academy of Sciences, consisted of a powerful radiation of electromagnetic waves.

In all his life, Prioré tried to increase the power of his appliances in order to improve their efficiency.

Supported by the most renowned scientists, he got some enormous state and industrial financial assistance (more than twenty million franc, approx. 3 million dollars) to finalize a machine permitting to validate his results in an unquestionable way. Unfortunately, he used this amount for the construction of a last apparatus with technologically limited possibilities. An apparatus with such a power that it would be able to cure any incurable human tumour or illness.

Refusing all collaborations in order to protect his "secrets", he succeeded in constructing a huge "generator" which was inaugurated by the French Prime Minister, J. Chaban-Delmas.

Several members of the Pasteur Institute tested the unit with success and confirmed the extraordinary possibilities of the apparatus.

The machine is reported to be comprised of the following:

a large plasma tube excited by 430 V
2) a magnetron oscillator (9.4 Ghz, 40 Kw peak), which pulsed on for 1 micro-seconds at a rate of 1 Khz
3) two high frequency oscillators (17.6 Mhz and 15.8 Mhz)
4) and a magnetic field (1200 G) which confines the plasma and which is pulsed at a rate of 50 times per minute. (G = Gauss a measure of magnetic field strength)

The magnetron and the two high-frequency signals are mixed in the plasma so that the 9.4 Ghz signal is modulated by the two high-frequency signals. The magnetic field at the table, where the subject is located, is about 600 G. (A second machine was also built which was capable of producing an active magnetic field of about 1200 G.)

Priore Machine

Several experiments have been carried out. Some of these are summarized below:

1. A cancerous tissue was grafted to laboratory rats. Twenty-four control rats died within 22-30 days. In those rats which had been exposed to radiation to the magnetic field from Priore’s machine, the cancerous tissue was either completely absorbed, or, if the treatment was begun after cancer had started to spread, had regressed to the point of total cure.There were no observed bad side effects and there was no recurrence of the cancer.

2. A different and highly malignant strain of cancerous tissue, leukaemia, which can cause death in as little as two weeks, was grafted onto laboratory rats. Again, exposure to the radiation in the magnetic field resulted in the complete inhibition of growth of the cancerous grafts, or, if the disease had started to develop before the treatment was begun, to its total regression.

3. Mice were inoculation with a microscopic blood parasitic (Trypanosoma equiperdum) which causes sleeping sickness and death in short time. The course of the experiment could be followed closely by analyzing blood samples taken daily. All control animals died by the fifth day. Mice exposed daily to the radiation and magnetic field survived (38 out of 46 animals) with complete disappearance of the parasites from their systems.They also developed a specific immunity to further infection. Animals exposed some days before inoculation appeared to have developed an immunity.

4. Rabbits, which develop a chronic illness when inoculated with trypanosomes from which they usually die after several weeks, were tested with the radiation in a magnetic field with the same positive results as described above.

A twenty-man commission composed of well known men of science, medicine, law and other professionals, have begun and are continuing investigations into the claims made for this mystery machine. They have been able to report experimental findings, but have not been able to provide an explanation of the workings of the Prioré equipment. Funding was provided by the French Government to construct a third and more powerful machine which cost 3.5 million dollars. It was called the M-600 and functioned for about one week until a huge tube in it exploded. Due to the inflation rampant in the early 70’s, the replacement cost would have exceeded one million dollars which was felt to be too high to continue the project.

The story of this remarkable work began in 1944 when Antoine Prioré noticed some oranges which had been left in a room next to some electrical equipment. These oranges remained in a fresh state while others not near the electrical equipment became rotten and putrid. This anomaly intrigued young Prioré to explore magnetic and electromagnetic effects on various plants. One of his earlier experiments was the exposure of lentil seeds to a magnetic field of 225 gauss at electromagnetic frequencies of 80, 32, 3 and 10 Hertz. This caused the lentils to grow 12-15 centimeters in length as compared to only a 5 centimeter growth for controls not subjected to the same treatment. The effect proved similar for asparagus, tulips, and other plants. Hens’ eggs were then exposed to the same energies which brought about hatching in 19 days as opposed to the normal 21 days. Later research using cancerous tissue yielded partial or total remissions when exposed to these energies.

Similar reports of tumor regressions were obtained by Kenneth McLean with the use of a 3000 gauss or greater magnetic field. Later tests made by Biraben and Delmon using a field strength of 4500 gauss on T-8 tumors had not the slightest trace of remission. This showed that there was obviously something besides a magnetic field at work.

Tests made with the Prioré machine on cancer tissues ALWAYS caused total remission in all tissues exposed to the peach blossom violet color which the machine emitted. The machines of Antoine Prioré were dismantled shortly after his death in the early 80’s. Rumours say that research on his equipment is continuing in South Africa.

The Prioré system has been studied in France for 15 years by an independant group of doctors and researchers who have recovered the last Prioré machine.
The group is called "Laboratoire ARTEC" and their and web site is or for the English pages.

Comments on the Prioré Machine by Aubrey Scoon, a prominent Rife researcher:

"As for the Priore machine. It was basically a microwave emitter modulated with RF which also had a strong magnetic field. Now look up Priore's own research papers and see how when parts of his machine failed it carried on working regardless! After reducing all the bits that were probably irrelevant you end up with an overblown Rife machine. He was even using Rife's frequencies! Do you need quantum mechanics to describe how a Rife machine can work? I don't think so. We haven't even tried, let alone exhausted any of the conventional explanations yet!"

Le laboratoire ARTEC
The following text has been Google translated into English from the more detailed French pages on While some improvements have been made, we accept no responsibilty for any translation errors.

Founded fifteen years ago this laboratory brings together, in an independent associative structure of some academics, doctors, engineers, technicians, sharing an original vision of the operation of the Priore devices. Experts from all backgrounds occasionally bring their expertise to the design or realization of research materials.
Fully-independent funding allows for complete independence. In this framework they can work beyond any intellectual conformity or concerns for their careers.

1 - Origin
Prioré died in 1983. A small group of doctors and scientists, led by Dr. Murzeau, decided to take an interest in the case. None of them had been involved with this technology, before. The research status was appalling.

There was a juridico-financial dispute coupled with formidable rivalries between the various actors with diverging interests. These are acute conflicts of people hurt in their own ways and bitter due to the failures and reject responsibility for it.

The equipment is out of order in the widow's home, who denies access to it. Ownership of this equipment is claimed - at least for the last machine - by the company Leroy-Sommer, which financed it.

The industrialist wants a return of his funds (he invested more than ten million francs of the time - 1.3 million Euros) by relaunching the "machine" of which he provided the main elements and solicits a large subsidy from the state.

The state that has been a backer, also has a say, not to mention an Italian wife and a descent that the inventor had "forgotten".

There are very conflicting relations between Professor Pautrizel and the industrialist, the physicists of the Bordeaux Faculty and the widow who, under pressure from all sides, refuses any cooperation. Isolated, with no real means (his INSERM unit being suppressed) Pautrizel is incalable of doing anything. Desiring to play a role, he was reluctant to disseminate the abundant documentation at his disposal and in vain sought the creation of associations and petitions requiring the resumption of research.

2 - The Survey
In a first phase all energy is devoted to uniting these dispersed forces. In vain ! The antagonisms are too strong.

Dr. Murzeau: "We then decide to undertake a vast investigation to gather a complete file on the" case "in the hope of convincing anyone who would like to resume the experiment ... This enormous work required three years of collection , Analysis and study of a mass of documents, which we wish to present in a clear way, based essentially on the scientific results. "

In order to facilitate the task of a potential candidate, the specification studies the realization of a simple device capable of demonstrating reliably and reproducibly the double effect Priore . In case of success there will not be wanting of demands to develop machines more powerful.

The complexity of the latest technological monsters completely masks their basic principles. Rather than promoting the construction of a large apparatus, we are particularly interested in the first successes achieved in the 50s. Curiously, this period has been totally neglected by all who are interested in the case. And yet the harvest is exceptional!

At that time (as early as 1948) Priore obtained very appreciable results with a much more modest recovery apparatus: the apparatus is held on a small table! The study of the characteristics common to the complex assemblies that the inventor will evolve during the next ten years is very instructive.

She appeals to the memories of her close friends, her early companions, the craftsmen of the beginning, the staff later put at her disposal, etc. All modest, admiring Priore to whom he did not shade, the one It shared with them good and bad moments and sometimes poured out. These particularly valuable testimonies confirm the simplicity of the basic process used ("it is so simple that they" will never find "), simple process but a delicate application and which will be more and more as and when Measuring the power increase of the devices.

Key data will be collected on Priore's primary experiments and on some "tricks" used for his adjustments.

Nb: When he later proposed this information to the physicists of the Faculty, Dr. Murzeau heard himself answer: "We do not work with amateurs!" The lesson was learned. Some time later seeing himself again dismissed he will deposit under the mat a few documents in case ...

The second lesson is the incredible poverty of Priore's scientific culture.
Certainly he was an excellent technician capable of performing complex radio mounts, but he was astounded by the basic questions he was shed by certain specialists. This theoretical desert often leads him into unlikely confusions of terms and understanding between the properties of electric fields, magnetic fields, electrons, particle radiations, various forces ... In no case could his results come from elaborate hypotheses or from Scientific calculations. He tried to build a "sticky" theory to his mysterious discovery.

Nevertheless, this absence of knowledge makes it possible to take an interest in the work of Priore without having an important theoretical background.

Forgotten documents
Stroke of luck ! A briefcase belonging to dr. Fournier, the first learned companion of Priore, was exhumed from the granary of a notary. Maurice Fournier from the first hour had experimented with Priore and threw for him the scientific bases of the effects. Its contents were very instructive for those who knew how to read. Besides numerous notes on the functioning and the biological hypotheses, one learns there belonging to Roses-Cross, sect to the smoky theories to which Priore was initiated. This illuminates certain "vibratory" aspects of his delusional theories. Once again, it was only a matter of explaining his results.

Dr. Berlureau, a veterinary surgeon, who had come a little later, had recorded a host of elements of all kinds. No theory but abundant and original documents recounting the essence of the experiments.

Numerous other documents of various origins are collected together with a precise state of the hundreds of experiments carried out throughout this epic.

Priore's theories concerning the internal functioning and mode of action of his apparatus, as well as how to improve them, however absurd, inform the method he applied.

It is therefore by studying these sources, comparing them with other methods of electrotherapy in vogue at the beginning of the century (lakhovsky), but also by analyzing the failures of all attempts to reproduce the apparatuses Can finally reveal the main features of this enigma. This work is tedious but it can not be saved because there are enormous misinterpretations. The failure of the best teams is an illustration of this.

3 - The laboratory
In the beginning: practical work

In order to complete the specifications, the construction of an apparatus combining the main functions of the machines of Priore, synthesis of previous studies, is undertaken. It is only a question of "practical work" in order to improve the understanding of the ill-defined role of a particular component often found.

As the problems raised by any prototype were overcome, thanks to numerous tests, different questions were answered. The obligation to design parts (especially the plasma tube), special assemblies, and to make work in harmony unusual energy sources leads in some way in the footsteps of Priore. Incentive to push construction further.

Progressively one comes to complete a consequent apparatus associating radio waves, radar, magnetic field, plasma, etc in Faraday cage. As the work progresses, certain principles of operation emerge and it is obvious that the design of the apparatus does not allow it to produce the Priore effect. It was conceived only as a study material.

This brings us to the end of the first epoch. The thorough investigation carried out, the documents compiled, the technical part cleared no candidate will accept to resume the deal! Too heavy to maintain the association goes into an apparent sleep. Ten years, the study of documents, the deepening of knowledge, complementary investigation and follow-up of recent work will not slacken.
