Johanne was born the third child in Saint-Omer, northern France, where she studied art and naturopathy. During her exploration of naturopathy, she met the renowned naturopath Josef Angerer from Munich. She subsequently worked with him for many years, illustrating his books and writing her own texts under his guidance. She took on the role of his personal assistant and was eventually commissioned to write and design the seventh and final volume of his pioneering work, "The Ophthalmotrophic Phenomenology" and "The Ophthalmotrophic Environment."

In the course of her research, Johanne came across the Essene Gospel, which she recognized as the authentic message of the holy man who traveled through Judea in the first century A.D. After intensive study, she realized that the Essene Gospel served as a precursor to the New Testament and that it had been deliberately distorted according to certain principles and intentions.

The trilogy “The Mystery of the True Gospel” is the result of seven years of intensive research and, based on historical documents, proves the authenticity and antiquity of the Essene Gospel, which, according to Edmond Szekely, is kept in the secret archives of the Vatican.

In 2017, Johanne met Professor Max Ludwig Fischer, a friend of the Szekely family. He encouraged her to write an abridged version of the trilogy. That year, the study "The Essene Gospel and Its Falsification" was published in both German and English.

A year later, thanks in part to the support and efforts of Professor Fischer, John's work was examined by numerous theology professors from the United States. After months of analysis, they concluded that it had succeeded in proving the authenticity of the Essene Gospel.
