Beethoven most likely died from liver failure related to cirrhosis , with alcohol use, hepatitis B, and genetic susceptibility all likely contributing. Some studies also found high lead exposure, but that is now seen more as a possible factor in his long-term illness than the sole cause of death.

What the evidence suggests

  • A medical review of his autopsy and later analyses concluded he had cirrhosis of the liver and probably died from liver failure, with kidney failure complicating the final stage.
  • A 2023 genome study found evidence of hepatitis B infection and a genetic risk for liver disease, pointing to a combination of factors rather than one single cause.
  • Older theories blamed lead poisoning, but newer research says lead exposure probably was not the direct cause of death, though it may have worsened his health.

In plain terms

The best-supported answer is that Beethoven died of severe liver disease , likely from a mix of chronic alcohol use, hepatitis B, and inherited risk.

Date

Beethoven died on March 26, 1827.
