Society: Arts and Science – April 25


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.
Guglielmo Marconi, 1st Marchese of Marconi was born on this date in 1874. He was an Italian inventor and electrical engineer, known for his pioneering work on long-distance radio transmission and for his development of Marconi’s law and a radio telegraph system. Marconi is often credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun “in recognition of their contributions to the development of wireless telegraphy”. An entrepreneur, businessman, and founder in 1897 of The Wireless Telegraph & Signal Company (which became the Marconi Company), Marconi succeeded in making a commercial success of radio by innovating and building on the work of previous experimenters and physicists. In 1924, the King of Italy ennobled Marconi as a Marchese.
Wolfgang Ernst Pauli was born on this date in 1900. He was an Austrian-born Swiss theoretical physicist and one of the pioneers of quantum physics. In 1945, after having been nominated by Albert Einstein, Pauli received the 1945 Nobel Prize in Physics for his “decisive contribution through his discovery of a new law of Nature, the exclusion principle or Pauli principle.” The discovery involved spin theory, which is the basis of a theory of the structure of matter.
