(born April 23, 1867, Silkeborg, Den.—died Jan. 30, 1928, Copenhagen) Danish pathologist. He found that rats that had suffered stomach-tissue inflammation caused by the larvae of a worm infecting cockroaches the rats had eaten subsequently developed stomach tumours, and he induced tumours in mice and rats by feeding them infected cockroaches. His work, for which he received a 1926 Nobel Prize, supported the prevailing concept that cancer is caused by tissue irritation and led to production of chemical carcinogens for use in cancer research.
