Ludwig van Beethoven was a prodigious composer. He’s credited with 722 particular person works, together with symphonies, sonatas, and choral music — creations that pushed the boundaries of composition and efficiency, and helped usher within the Romantic period of music. However away from the fortepiano, Beethoven’s life was tormented by deafness, debilitating gastrointestinal troubles, and jaundice.
A little bit greater than a yr in the past, scientists introduced that they’d sequenced Beethoven’s genome from preserved locks of his hair. They discovered genetic danger elements for liver illness, however nothing else terribly conclusive.
However some researchers have lengthy puzzled whether or not among the solutions lay past his genes — particularly, whether or not toxicity from heavy metals may need had one thing to do along with his many illnesses.
Now, after testing just a few extra strands of the composer’s hair, a workforce of scientists recommend within the journal Medical Chemistry that Beethoven was virtually definitely uncovered to guide — and that it might have contributed to the well being points that have been such a characteristic of the storied composer’s life.
The struggles of Ludwig van Beethoven
Lead is a poisonous steel that’s naturally discovered within the Earth’s crust. Nevertheless, “its widespread use has resulted in intensive environmental contamination, human publicity and vital public well being issues in lots of components of the world,” in keeping with World Well being Group.
“Lead has no helpful goal within the physique,” says Howard Hu, a physician-epidemiologist on the College of Southern California. “However sadly, it additionally mimics among the different extra important parts. It’s an imposter. It will get included into varied enzyme and molecular constructions within the physique after which screws them up.”
And that may result in all types of points, from mind harm to hypertension to kidney issues.
Beethoven started shedding his listening to in his mid to late 20s and was totally deaf by his mid 40s. As well as, he suffered from jaundice and crippling GI issues. At one level he wrote his brothers a letter, now named the Heiligenstadt Testomony, asking that his well being issues be described after his demise.
“He had wished the world to know the reality behind the reason for his illnesses,” explains Paul Jannetto, the director of the Metals Laboratory on the Mayo Clinic.
The Metals Laboratory normally assessments blood and urine samples for publicity to heavy metals, like lead, mercury, and arsenic. “Clinically, our take a look at menu is actually the periodic desk,” says Jannetto. Among the many lab’s typical obligations is screening children for result in attempt to decide if a affected person’s signs is perhaps attributable to heavy steel toxicity.
So Jannetto vividly remembers the second a colleague despatched him a really completely different request: Would he be prepared to check Beethoven’s hair for heavy metals?
These two locks of Beethoven’s hair have been examined for lead in 2023.

When somebody is uncovered to guide, among the dangerous steel will get deposited of their hair. Which means even with no blood pattern, scientists can use somebody’s hair to find out their lead ranges posthumously.
So the proprietor of two separate locks of Beethoven’s hair put one thing like two or three dozen strands in a particular assortment package and shipped it to the Mayo Clinic — the place Sarah Erdahl, Technical Coordinator on the Metals Lab, acquired it.
“I used tweezers,” says Erdahl, who mentioned she felt zero temptation to the touch the composer’s hair together with her naked arms. “My coronary heart was fluttering and I used to be like, ‘Oh my goodness, that is so vital.’ When you’ve gotten that small quantity of hair, each strand counts.”
Jannetto agreed, including that this strategy is one which extends to the lab’s customary, residing sufferers.
“Behind each pattern — whether or not it’s blood [or] hair — is an individual,” he says. “And that’s why it’s valuable and we deal with it with care.”
Erdahl rigorously rinsed and handled the hair earlier than working it by means of the instrument that measures heavy metals. The degrees of arsenic and mercury in Beethoven’s hair have been barely elevated.
The lead ranges, however, have been a startling 64 to 95 instances greater than the hair of somebody at present.
It was a dramatic reveal — which may clarify why, in that second, the opening bars of Beethoven’s fifth Symphony crashed by means of Erdahl’s mind:
“Dun dun dun dun.”
“That is a lot extra elevated than another affected person samples we’re seeing,” she remembers pondering. “That is extraordinarily vital.”
The place classical music meets heavy steel
That substantial buildup of the poisonous steel doubtless got here from the goblets and glasses Beethoven drank out of, sure medical remedies of that age, and his consumption of wine.
“We do know Beethoven beloved his wine,” says Jannetto. “And again then, it was not unusual to truly add lead acetate to the inexpensive wines as a result of it binds the acids so as to add a sweeter taste to the wine.”
Jannetto says that even for folks of his time interval, the lead ranges in Beethoven’s hair would have been about 10 instances greater than common. “What this confirmed is he had a continual publicity to excessive concentrations of lead,” he says.
The lead wouldn’t have killed him, however it doubtless contributed to his well being issues.
“A whole lot of these documented illnesses that Beethoven had,” says Jannetto, “these are conventional indicators and signs {that a} neurologist or clinician may see in a affected person that was uncovered to guide.” These embrace liver illness (which might have been aggravated by his genetic danger issue, common ingesting, and an infection with hepatitis B), gastrointestinal challenges, and listening to loss.
Hu, who wasn’t concerned within the analysis, praised the work.
“That’s some good science,” he says. “I feel it was fairly darn rigorous.”
Hu has studied lead publicity and toxicity for nearly 40 years, together with within the context of some low- and middle-income international locations the place lead contamination can nonetheless be an issue.
“It’s nonetheless a significant downside globally,” he says, “due to lead contamination in spices and cookware and all kinds of different sources all over the world.”
Nonetheless, Hu can’t assist however mirror on how Beethoven managed his virtuosic composing despite the lead.
“It makes you much more awestruck by what he was in a position to accomplish,” Hu says.
He wonders whether or not maybe the very battle along with his well being helped form the emotional contours of a few of Beethoven’s compositions.
“I don’t know,” Hu chuckles. “It’s enjoyable to invest about it.”
