Beethoven's DNA Reveals a Surprise 200 Years Later

A 2023 genetic study of authenticated Beethoven hair found evidence of hepatitis B and inherited liver-disease risk.

The DNA analysis did not identify a clear genetic cause for Beethoven’s deafness or gastrointestinal illness.

Researchers also showed that a famous hair sample linked to lead poisoning was not Beethoven’s hair, weakening that theory of his death.
