In 1990, I, Peter Friedrich, purchased the Radar repertorization program from CSP, which included the "Synthesis." It was well known that this new repertory had been created by Dr. Frederik Schroyens (see copy of the invoice).
The computer version of the Synthesis program was continually elaborated, and these expansions were carried out by Dr. Frederik Schroyens.
From 1990 onward, we – Peter and Edeltraud Friedrich – worked on corrections to additions in the "Synthesis" and later contributed to the Materia Medica. Therefore, there was ongoing contact with Dr. Frederik Schroyens.
In 1993, the "Synthesis" was published in book form, also in German. This was the repertory by Dr. Frederik Schroyens.
In May 2003, the Archibel Teacher's Convention took place in Munich, moderated by Dr. Frederik Schroyens, who was presented as the "Editor of Synthesis” in the event materials (see copy).
From the very beginning it was known to us that the "Synthesis" repertory was created by Dr. Frederik Schroyens, and that he carried out the relevant revisions in collaboration with many homeopaths.
From our perspective and experience Dr. Frederik Schroyens is to be considered the "intellectual mastermind" of the "Synthesis" repertory.
