Johannes Andreas Grib Fibiger

Johannes Andreas Grib Fibiger was a Danish physician and professor of anatomical pathology at the University of Copenhagen. He was the recipient of the 1926 Nobel Prize in Physiology or Medicine "for his discovery of the Spiroptera carcinoma". He demonstrated that the roundworm which he called Spiroptera carcinoma could cause stomach cancer in rats and mice. His experimental results were later proven to be a case of mistaken conclusion. Erling Norrby, who had served as the Permanent Secretary of the Royal Swedish Academy of Sciences and Professor and Chairman of Virology at the Karolinska Institute, declared Fibiger's Nobel Prize as "one of the biggest blunders made by the Karolinska Institute."
