New research confirms that Beethoven had lead poisoning -- but it didn't kill him
WASHINGTON, May 6, 2024 /PRNewswire/ -- To this day, no one knows for certain what caused the liver and kidney disease that led to Ludwig van Beethoven's untimely death. However, a new letter to the editor in the Association for Diagnostics & Laboratory Medicine's (ADLM's, formerly AACC's) journal Clinical Chemistry rules out one popular theory, showing that the composer was exposed to lead levels that were high — but not high enough to kill him.
- High lead levels are commonly associated with all of these conditions — and are also associated with other traits of Beethoven's, such as his infamous temper, memory lapses, and chronic clumsiness.
- However, further studies eventually found that that lock of hair belonged to a woman, not Beethoven.
- Rifai's group analyzed the locks for lead using two different versions of a highly accurate testing technique known as mass spectrometry.
- From this, the researchers were able to estimate that Beethoven's blood lead concentration would have been 69 to 71 µg/dL.
