Lead poisoning linked to death
Lead poisoning linked to death The Vancouver Sun October 19, 2000 "Lead poisoning
linked to death" Ludwig von Beethoven, the famous composer, may
have died from lead poisoning. Beethoven, who died at the age of 57
in 1827, suffered from severe abdominal pain, depression and
irritability, which are all symptoms of lead poisoning. A four year
study of Beethoven’s hair found high concentrations of lead
–more than 100 times the amount found in healthy human hair.
However, the source of the lead contamination remains a
