Nobel Prizes

In 1901, at the first Nobel Prize Award Ceremony, the king of Sweden distributed the first Nobel Prizes, in accordance with the will of inventor Alfred Nobel. The day was the anniversary of Nobel's death. The Royal Swedish Academy of Sciences had decided on 10 Nov 1901 to award the first Nobel Prize in Physics to Wilhelm Röntgen for his discovery of X-rays and the first Nobel Prize in Chemistry to Jacobus H. van't Hoff for his work on rates of reaction, equilibrium and osmotic pressure. The first Nobel Prize in Physiology or Medicine was given to Emil von Behring, for his work on serum therapy, particularly for its use in the treatment of diphtheria. His Nobel diploma was dated 30 Oct 1901, signed by staff at Karolinska Institutet in Stockholm.«
