Johannes Fibiger, a Danish pathologist and bacteriologist who improved public health and research on cancer revitalized, was born that day
in 1867. early in his career, Fibiger discovered that there are two distinct forms of diphtheria, a disease that caused frequent epidemics in children and remains a problem in parts of the world. Based on the finding, Fibiger developed an antitoxin that was successfully tested in 1897.
At the turn of the century, cancer research has been stagnant because scientists did not know how to provoke cancer in laboratory animals. In 107 Fibiger noticed that some TB rats showed gastric tumors infested with tiny worms called nematodes. Intrigued, he investigated the source of the rats, a sugar refinery. Having collected cockroaches from the refinery, Fibiger fed them to rats that had been trapped elsewhere. When the first dead rat, he found stomach cancer. To create the first reproducible animal model of cancer, Fibiger received the Nobel Prize for medicine in 1926. He died two years later
