johannes andreas grib fibiger -lrb- 23 april 1867 -- 30 january 1928 -rrb- was a danish scientist , physician , and professor of pathological anatomy who won the 1926 nobel prize in physiology or medicine .
fibiger had claimed to find an organism he called `` spiroptera carcinoma '' that caused cancer in mice and rats .
he received a nobel prize for this discovery .
later , it was shown that this specific organism was not the primary cause of the tumors .
moreover , katsusaburo yamagiwa , only two years later in 1915 successfully induced squamous cell carcinoma by painting crude coal tar on the inner surface of rabbits ' ears .
yamagiwa 's work has become the primary basis for this line of research .
because of this , some consider fibiger 's nobel prize to be undeserved particularly because yamagiwa did not receive the prize .
`` encyclopædia britannica '' 's guide to nobel prizes in cancer research mentions yamagiwa 's work as a milestone without mentioning fibiger .
