Researchers
using Argonnes Advanced
Photon Source (APS) have confirmed that composer Ludwig van
Beethovens years of chronic illness were due to lead poisoning.
This toxin also may have contributed to the 19th-century composers
death.
Chemical analysis
showed extraordinarily high levels of lead in strands of Beethovens
hair, according to William Walsh, chief scientist for the Health
Research Institute in Naperville, Ill. The institute performs
chemical analysis of trace elements in the hair of children and
adults and relates it to nutritional and biological conditions that
contribute to behavior disorders and mental illness. Walsh led the
Beethoven hair study in collaboration with Argonne physicists.
The team performed
nondestructive X-ray beam experiments involving side-by-side testing
of six Beethoven hairs, a standard hair of known lead composition
and a thin film of standard "lead glass" with a known
lead composition.
They found elevated
lead levels that averaged about 60 parts per million (ppm) in the
six Beethoven hairs, confirming earlier findings at Chicagos
McCrone Research Institute. According
to Walsh, average Americans today have 0.6 ppm of lead in their
hair, about 100 times less than Beethoven.
Researchers
performed the elemental X-ray fluorescence analysis at the APS Synchrotron
Radiation Instrumentation Collaborative Access Teams (SRI-CAT)
beamline. SRI-CAT focuses on developing new instrumentation
and techniques for the synchrotron radiation community as well as
providing beam time for experiments.
Researchers
will continue studying the hair. "The APS is the only machine
in the country where we can perform the research we have planned,"
said Ken Kemner, one of the group of Argonne researchers involved
in the project. The group plans to use microimaging to look at the
distribution of lead in and on the hair to identify the presence
of any surface effects and to determine the degree of recent lead
exposure. "The hair is a timeline of exposure," Kemner
said. "Well be able to determine his exposure during
the last six months of his life since that is about the amount of
hair we have. We hope to determine if the lead levels were due to
diet, and if there were multiple high doses or high background amounts."
"Beethoven
saw physician after physician in search of a cure for his physical
ailments," said Walsh. "He suffered from bad digestion,
chronic abdominal pain, irritability and depression. Since he died
in 1827 at age 57, there has been much speculation but no proof
of the cause of his illnesses and death."
Lead poisoning
could explain his life-long illnesses. "It would also have
had an impact on his personality and could have contributed to his
death," said Walsh. Walsh doubts that lead poisoning caused
his deafness, but research continues.
The source of
the lead poisoning is unknown but could have been from drinking
mineral water at spas, from dishes or wine stored in lead-lined
flasks or lead crystal.
"You can
learn a great deal about a person from hair analysis," said
Walsh. He looked for distinctive trace-metal patterns associated
with genius, irritability, glucose disorders and malabsorption and
found they were not present in the Beethoven samples.
He also looked
for the presence of mercury, which would have suggested that Beethoven
received medical treatment for syphilis, which was usually treated
in that period with mercury compounds, and which some Beethoven
scholars suspected he had contracted. No mercury was found.
