Society: Arts and Science – September 2

The Nobel Prize is bestowed annually in categories as selected by Swedish and Norwegian committees in recognition of cultural or scientific advances. The 1895 will of Swedish inventor Alfred Nobel established the prizes.
Friedrich Wilhelm Ostwald was born on this date in 1853. He was a Baltic German chemist. He received the Nobel Prize in Chemistry in 1909 for his work on catalysis, chemical equilibria and reaction velocities. Ostwald, Jacobus Henricus van ‘t Hoff, and Svante Arrhenius are usually credited with being the modern founders of the field of physical chemistry.
Frederick Soddy FRS was born on this date in 1877. He was an English radiochemist who explained, with Ernest Rutherford, that radioactivity is due to the transmutation of elements, now known to involve nuclear reactions. He also proved the existence of isotopes of certain radioactive elements. He received the Nobel Prize in Chemistry in 1921 and the same year he was elected member of the International Atomic Weights Committee. A small crater on the far side of the Moon as well as the radioactive Uranium mineral Soddyite are named after him.
