# bio (long form, separated for readability)
bio: |
  Artturi Ilmari Virtanen was born on 15 January 1895 in Finland, trained as a chemist, and turned his attention to a problem farmers knew too well: fodder spoils, cows go hungry, milk dries up. He developed AIV silage, a preservation method that kept feed fresh longer and lifted milk production wherever it spread. He also worked out a way to preserve butter using AIV salt, which opened export routes and put Finnish butter on foreign tables. The Nobel committee gave him the prize in Chemistry in 1945 for his research and inventions in agricultural and nutrition chemistry. He died on 11 November 1973.
