The Institute of Legal Medicine, Innsbruck Medical University, has determined the "Friedrich-Schiller-Code". There were two skulls that have been reported to belong to Friedrich Schiller, the so-called "Fürstengruft-" and the "Froriep-skull". DNA analysis should identify the correct one.

The Friedrich-Schiller-Code

The Institute of Legal Medicine, Innsbruck Medical University harbours the Austrian Central DNA-Laboratory of the Ministry of the Interior, which is also known as an internationally renowned reference DNA laboratory. It is the first forensic DNA laboratory to be accredited (ISO 17025) in the German speaking field of legal medicine. Besides its core task as crime scene investigation laboratory it has successfully handled prominent identification cases.

The Friedrich-Schiller-Code

The "Friedrich-Schiller-Code" was determined by a team of 9 scientists and 4 technical staff members in a total of about 1,100 single DNA analyses.

For the identification of the "Friedrich-Schiller-Code" latest DNA technology was applied and the following DNA-systems were investigated:
Autosomal STRs (=Short Tandem Repeats) are inherited from both parents to their children and are therefore suitable for the analysis of paternity constellations. Due to their high variability autosomal STRs are also applied for human identification cases such as for stains found at crime scenes.

Y-chromosomal STRs are passed from fathers to their sons exclusively. By comparison relatedness within the male lineage can be tested and excluded with high certainty when the Y-STR profiles are not identical.

Mitochondrial (mt)DNA is passed from mothers to their children of both sex. By comparison relatedness within the maternal lineage can be tested and excluded with high certainty when the mtDNA profiles are not identical.

The Armed Forces DNA Identification Laboratory (AFDIL, Rockville MD) performed independent DNA anaylses on the samples. All DNA results between Innsbruck und Rockville were identical to each other. There were no differences in the investigated markers.

Research has been performed on two different skulls, on the assumed skull of Friedrich Schiller ("Fürstengruft"-skull), and on a skull attributed to Friedrich Schiller in former times ("Froriep"-skull).

The "Froriep"-skull from an adjoining room of the Fürstengruft harbours a female DNA-profile and is likely to originate from Louise von Göchhausen.

Let’s look at the results from the assumed skull of Friedrich Schiller ("Fürstengruft"-skull) and the detection of the Friedrich-Schiller-Code.

The Friedrich-Schiller-Code

The mtDNA of Friedrich Schiller's sister Christophine Reinwald matched the mtDNA of other maternal relatives buried in Möckmühl. Therefore, the mtDNA-Schiller-Code is established. The mtDNA of the "Fürstengruft-skull" is different and does either not belong to Friedrich Schiller or he and his sisters had different mothers (theory of the changeling).

The Friedrich-Schiller-Code

Schiller's sons Ernst and Karl and his son Ernst have the same Y-chromosomal DNA, which constitutes Friedrich Schiller's Y-Code. This one is different to the one of the "Fürstengruft-skull". Therefore, the skull can only be from Friedrich Schiller, if he was a changeling and not the biological father of the two brothers Ernst and Karl.

The Friedrich-Schiller-Code

The autosomal STRs analyses unambiguously demonstrate that Charlotte is the biological mother and Christophine Reinwald the aunt of Ernst and Karl. The two families are now linked by DNA which requires a direct male relative of Christophine to pass it to the next generation. Friedrich Schiller was the only possible person to pass the DNA, as there is no other male relative to be considered.

Thus, the "Fürstengruft-skull" cannot belong to Friedrich Schiller, as the Y-chromosomal DNA results do not match to the sons.
