    Extractions: Virtanen was educated at the university in his native city of Helsinki, where he obtained his PhD in 1919, and at the universities of Zurich and Stockholm. He worked from 1921 to 1931 as director of the Finnish Cooperative Dairies Association Laboratory and from 1924 at the University of Helsinki where, in 1931, he became director of the Biochemical Institute. In 1945 Virtanen was awarded the Nobel Prize for chemistry for his method of fodder preservation. This AIV method, as it became known, named for his initials, was designed to stop the loss of nitrogenous material in storage. By storing green fodder in an acid medium he hoped to prevent spoilage and still retain nutritious fodder. After much experimentation he finally found that a mixture of hydrochloric and sulfuric acid was adequate as long as its strength was kept within certain precise limits. Specifically, this demanded a pH of about four. In 1929 Virtanen found that cows fed on silage produced by his method gave milk indistinguishable in taste from that of cows fed on normal fodder. Further, it was just as rich in both vitamin A and C.

    Extractions: Virtanen, Artturi Ilmari Le premier prix Nobel finlandais est né à Helsinki le 15 janvier 1895. Après avoir étudié la chimie à l'Université de sa ville natale, il obtient en 1918 le grade de docteur, ayant préparé sous la direction du professeur O. Aschan une thèse sur les acides résineux dans laquelle il établit la constitution de l'acide abiétique de la colophane du pin. Jugeant sa formation insuffisante, il étudie les techniques et les méthodes chimico-physiques et biochimiques à l'occasion de voyages "post-doc" en Suisse, en Allemagne et en Suède. En 1921, il accepte le poste de chef de laboratoire de l'organisation centrale des laiteries coopératives finnoises, la Valio. Virtanen est alors nommé maître de conférences à l'Université d'Helsinki (1924-1939); il enseigne également au cours de cette période (1931-1938) à l'Ecole Technique Supérieure d'Helsinki. Pédagogue original, il fait participer les étudiants les plus avancés aux travaux de recherche de l'Institut dont il assure la dierection. Il occupe ensuite, de 1939 à 1948, la chaire de biochimie à l'Université d'Helsinki. Tenant de la recherche fondamentale, Virtanen n'a jamais perdu de vue qu'elle devait pouvoir déboucher sur des applications techniques, lors même qu'elle semble s'en éloigner. Evoquant son entrée à la Valio, où son travail porte sur les problèmes pratiques posés par l'industrie laitière (détermination des taux de matière grasse, dosage de l'eau, mesure du pH), il écrit:

He studied the Classical Lyceum at Viipuri, Finland. After he finished school, he studied chemistry, biology, and physics. In 1939 he became Professor of Biochemistry at the Finland Institute of Technology at Helsinki and at the University of Helsinki in 1939. His research included partially synthetic cattle feeds, nitrogen-fixing bacteria in the root nodules and improved methods of butter preservation. In 1945 Virtanen became Nobel Prize Laureate in Chemistry, for his research in agricultural and nutrition chemistry, especially for his fodder preservation method (AIV Fodder). The method – which he had published 1943 - improved the storage of green fodder that is important during long winters. Process includes adding dilute hydrochloric or sulfuric acid to newly stored grain. Increased acidity stops harmful fermentation and has no adverse effect on the nutritive value of the fodder or animals that eat it. Books about 'Artturi Ilmari Virtanen' at: amazon.com
