The world renowned composer Ludwig van Beethoven was infected with hepatitis B when he died , concord to the first ever desoxyribonucleic acid analysis of the deaf instrumentalist ’s corpse .
The genetic depth psychology , conducted on five locks of Beethoven ’s fuzz taken as souvenir from his head during the last seven yr of his life , also revealed that he had a mellow risk of liver disease . This genetic risk along with the hepatitis B infection , which likely also damaged his liver , may have played a persona in his death . The find contradicts the wide - conceive suggestion that the composer die from lead poisoning , but does not drop twinkle on how he came to lose his hearing .
A portrait of Ludwig van Beethoven by Karl Joseph Stieler
Born in 1770 , Beethoven began to drop off his ability to hear in his mid - to - late-20s , becoming completely indifferent by his late-40s . He also suffered from more and more severe GI problem throughout his life , experience at least two attack of jaundice , a symptom of liver disease .

In 1802 , as his ailment grew in severity , Beethoven asked his doctor friend Johann Adam Schmidt to uncover and publicize the strange disease he was suffering from , but Schmidt died 18 year before Beethoven . After Beethoven ’s death in 1827 , a post - mortem revealed that he had terrible liver scarring , also love as cirrhosis . Now , the new research , publish Wednesday ( March 22 ) in the journalCurrent Biology , has find the genetic and viral basis for his illness , fulfilling the composer ’s petition at long last .
" We can not say emphatically what kill Beethoven , but we can now at least confirm the bearing of significant inheritable risk and an infection with hepatitis B virus , " study co - authorJohannes Krause , a professor of genetics at the Max Planck Institute for Evolutionary Anthropology , read in a statement . " We can also eliminate several other less plausible transmitted cause . "
To crack the great composer ’s genetic computer code , the researchers first arrange about enter out if the eight locks of his hair they had obtained from compendium in the U.S. and Europe were authentic . After usingDNAanalysis to determine the age of the lock ; comparing the deoxyribonucleic acid taken from each ; and assessing the results alongside the paperwork for each one , the researcher reason out that five of the locks came from Beethoven . Among the three ignore locks was the hair’s-breadth antecedently studied to evoke that he go bad of lead poisoning ; but the lock chamber is now think to have make out from an Ashkenazi Jewish woman .

Further DNA analytic thinking of the locks break the composer ’s high risk of liver disease , possibly because of a hereditary disorder called patrimonial iron-storage disease . The risk factor did not exceed one that would go unnoticed by most mass , but the investigator ’s believe Beethoven ’s well - documented love of alcoholic drink , alongside his transmission with hepatitis B — a computer virus which can damage the liver — could have caused him to acquire liver disease .
" demand in sight of the cognise medical story , it is highly probable that it was some combination of these three factors , include his alcohol pulmonary tuberculosis , acting in concert , but succeeding enquiry will have to clear up the extent to which each component was involved , " study lead authorTristan Begg , a geneticist and doctorial nominee of Biological Anthropology at the University of Cambridge in the U.K. , said in the instruction .
The study also revealed a strange enigma in Beethoven ’s category history . Comparisons made with the composer ’s living relatives showed that , though some shared a parental ancestor , their DNA did not match the Y - chromosome get hold in Beethoven ’s authenticated fuzz . The researcher say this is likely the result of an extracurricular intimacy somewhere in Beethoven ’s ancestral line that begat offspring .
" We hope that by making Beethoven ’s genome publicly available for researchers , and perhaps adding further authenticate locks to the initial chronological series , remain questions about his health and family tree can someday be answer , " Begg said .
