Johanne is the third child born in Saint-Omer, in the north of France. She studied art in Augsburg and naturopathy in Munich. 

It was through naturopathy that she met the great Munich naturopath Josef Angerer, with whom she worked for many years, illustrating his books and writing them under his supervision. She became his private assistant. Angerer finally commissioned her to write and edit the seventh and final volume of his pioneering work "Die Ophthalmotrophe Phänomenologie" and "Die Ophthalmotrophe Umwelt". 

It was in this way that Johanne discovered the Essene Gospel, which she recognised as the authentic message of the holy man who travelled through Palästina in the first century AD.

Years later, she realised that the Gospel of the Essenes was a precursor to the New Testament, that it had served as a model for the writing of the latter and that it had been deliberately falsified according to a precise principle and intention. 

The trilogy 'The Secret of the Gospel of the Essenes' is the result of these seven years of intensive research and proves, with the help of historical documents, the authenticity and antiquity of the Gospel of the Essenes, which, according to Edmond Szekely, is kept under lock and key in the secret archives of the Vatican. 

In 2017, Johanne met Professor Max Ludwig Fischer, a friend of the Szekely family, who advised her to write a short version of the trilogy. That same year, the study "The Essene Gospel and its falsification" was published in German and English.

A year later, thanks in part to the commitment and efforts of Professor Fischer, a large number of theology professors in the United States examined Johanne's work.
