Nobel Prize in Chemistry Recipient. Hans von Euler-Chelpin received world-wide recognition for receiving the 1929 Nobel Prize in Chemistry, according to the Nobel Prize committee, “for their investigations on the fermentation of sugar and fermentative enzymes." He received the coveted award jointly with Englishman, Arthur Harden. Born the son of a German military officer in the Royal Bavarian Regiment, his grandmother played a huge part in his childhood years. After finishing his early educations as serving an one-year volunteer in the Bavarian first Field Artillery Regiment, he wanted to pursue a career in art. He studied at Munich Academy at 1891 and 1893. While researching the problems of the spectrum of colors, he was led to study science. At this point, he entered the University of Berlin studying under acclaimed scientists such as Nobel Prize recipients as Emil Fischer and Max Planck. After studying in Berlin, he studied at the University of Göttingen from 1896 until 1897 under Nobel Prize recipient, Walther Nernst. In 1897 he accepted a position in the laboratory of Swedish Nobel Prize recipient Svante August Arrhenius in Stockholm. In 1899 he was appointed a Privatdozent in physical chemistry in the Royal University at Stockholm. Between 1899 and 1900 he studied with Nobel Prize recipient Jacobus van’Hoff. All these highly learned men greatly influenced his scientific growth. In 1923, he taught Artturi Virtanen, who had an interest in fermentation, and using his acquired knowledge to discover a means for better preserving the nutrients in have, benefitting countries with long, cold winters. This discovery led to Virtane’s 1945 Nobel Prize. He published many papers and textbooks including “Biochemistry of Tumors” in 1942 and “The Chemotherapy and Prophylaxis of Cancer” in 1962. Using his knowledge of colors, he researched colored vegetables comparing which color had what vitamin. In 1941 he formally retired, yet continued to do research. He married twice and had a total of nine children: With his first wife, Astrid Cleve, five children were born. The couple divorced in 1912. With his second wife, who he married in 1913, Elisabeth Baroness of Ugglas, four children were born. Both of his wives, who were scientist, collaborated with him in his research. His son Ulf von Euler was the 1970 Nobel Prize co-recipient in Physiology and Medicine, his son Georg von Euler was a judge, daughter Karin Stople was an author, and the remaining children excelled in their career fields.
