They found significant genetic risk factors for liver disease, which in combination with documented heavy alcohol consumption and evidence of hepatitis B infection provides the most evidentially grounded account yet of why Beethoven’s liver failed. They found that the genetic evidence could not identify a clear cause of his deafness or his gastrointestinal problems, though they excluded several specific proposed causes. They found, through comparison with living relatives, a discrepancy in the paternal line that stretched across approximately seven generations of documented family history.
And they found themselves unable to answer the questions that have always been most interesting about Beethoven: why he heard what he heard, why he wrote what he wrote, how a deaf man composed music that other people have been unable to stop listening to for two centuries.
The Heiligenstadt Testament’s wish was to have the illness understood. That wish has been partially honored. The illness is better understood than it was before 2023. The man remains what he always was: largely opaque in the ways that matter most, and legible mainly through the work.
