Gerard Croiset

If, one day, you go to Utrecht, you can ask the first person you see to indicate Gerard Croiset’s house.  This man is known to all Dutch people, but also to all the police forces in the world for the thousands of pieces of information he has given on missing persons and objects.

He retained his youthful vanity and sometimes could be heard to say:

“I am Croiset the Great”.

But he could also be very down-to-earth.

“Everyone has the same gifts as I have.  With me, they are only a bit more developed.  Everyone is in contact with other people, I just feel these contacts a bit more intensely.”

He was not without humour either, and he loved to laugh.  In 1958, he was coming back from Milan by air with Professor Tenhaeff.  The aeroplane was supposed to land in Amsterdam.  But, because of fog, it was announced that it would be landing in Bruxelles.

In his seat, Croiset bursts out in great guffaws of laughter.  His neighbour, thinking that he has gone mad, shrinks away from him.  He says to her:

“Don’t worry, Madam…  Do you know who I am?   I am the Great Croiset!”

The lady is suitably impressed.

“You are the famous Dutch clairvoyant?”

“I am, Madam.  And, this evening, the Great Croiset was not capable of forseeing that we weren’t going to land in Amsterdam!”


Professor W. H. C. Tenhaeff (left) of the University of Utrecht, studied the case of Gerard Croiset (right).

Holland’s Institute of Parapsychology is one of the best in the world.  Situated in Utrecht, it maintains permanent relations with the principal organisms which, in diverse countries – above all America – deal with extra-sensory perception.

It possesses several thousands of dossiers on Croiset’s clairvoyances, and thousands of attestations from police forces in Holland, Germany, the United States, etc.  The man who is at the origin of the Institute’s great prestige, and whose works are probably a generation ahead of those of his collegues, is Professor W. H. C. Tenhaeff.  This scholar who is, with Doctor Rhine of Duke University in the United States, the greatest specialist in the world of extra-sensory phenomena, devoted the latter part of his life to the Croiset case and participated in all of the Dutchman’s clairvoyancy seances, in particular the famous chair tests.


The chair test is an experiment which, because it is renewable, permitted Tenhaeff to realise certain essential progress in the knowledge of extra-sensory faculties.  It is in fact the possibility of repetition which is the first condition of scientific proof.

The number of a seat in a room where there is to be, in the future, a public meeting of some kind, is chosen at random.  The seats are never reserved and sometimes Croiset does not even know the town where this meeting is to be held.  Infallibly, he manages to guess, up to twenty-six days ahead, who is going to sit on this seat when the time comes, with many details which go from the complete physical description of the spectator to the relation of more or less important incidents in his personal life.  For example, he will say:

“This will be a young, slim man, in a dark suit, with short hair, like a crew-cut.  He has a little handkerchief showing from his breast pocket and has fallen on his left leg where he has a scar on the knee.  On his left, a middle-aged woman is seated.  She has a son who wears a sailor’s uniform.  This woman has lost a member of her family in a torpedoing off the Atlantic coast…”

The chair test has been repeated and verified hundreds of times, with an extremely low margin of error.


Over seventeen years of experimentation with Croiset and the chair test, this “precognition” which has nothing to do with telepathy, which simplifies the problem, indicates that real “secret gulfs” exist in the human mind.  If official science wanted to sound them, the extra-sensory gifts of primitive races – prescience of certain dangers, communication without words, capacity to heal, etc. – could be understood, and these gifts restored in the mechanised, diminished man of today.

This could then be used to accede to a greater knowledge of the Universe, of this hidden world, which, for the moment, is not accessible to our known senses.  A world where time and space are abolished and where thoughts and memories would have their own reality.


In the last period of his research, Einstein was more and more interested in extra-sensory perception…
