Artturi Ilmari Virtanen (1895–1973) was a Finnish chemist and Nobel laureate known for his significant contributions to biochemistry. He was born on 15 January 1895, in Helsinki, Finland, and passed away on 11 November 1973.
Virtanen's most notable work was in the field of agricultural and food chemistry. He developed a method for preserving green fodder, known as the AIV (Artturi Ilmari Virtanen) method, which involved treating silage with dilute solutions of acids. This innovation revolutionized the preservation of animal feed, particularly during times when fresh forage was not readily available.
In recognition of his groundbreaking work, Artturi Ilmari Virtanen was awarded the Nobel Prize in Chemistry in 1945. The Nobel Committee specifically acknowledged his research on the fermentation of agricultural products and his discoveries concerning the effects of vitamins on animal physiology.
Apart from his scientific contributions, Virtanen also had a notable career in academia and public service. He served as a professor of biochemistry at the University of Helsinki and was involved in various scientific and administrative roles in Finland.
Artturi Ilmari Virtanen's legacy extends beyond his individual achievements, as his research had a lasting impact on agriculture and food preservation, benefiting both animal nutrition and human health.
