Ernest Rutherford, 1st Baron Rutherford of Nelson, OM, FRS (30 August 1871–19 October 1937) was a New Zealand chemist and physicist who became known as the father of nuclear physics. He discovered that atoms have a small charged nucleus, and thereby pioneered the Rutherford model (or planetary model, which later evolved into the Bohr model or orbital model) of the atom, through his discovery of Rutherford scattering with his gold foil experiment. He was awarded the Nobel Prize in Chemistry in 1908. He is widely credited as splitting the atom in 1917 and leading the first experiment to "split the nucleus" in a controlled manner by two students under his direction, John Cockcroft and Ernest Walton in 1932.


Later years

He was knighted in 1914. In 1916 he was awarded the Hector Memorial Medal. In 1919 he returned to the Cavendish as Director. Under him, Nobel Prizes were awarded to Chadwick for discovering the neutron (in 1932), Cockcroft and Walton for an experiment which was to be known as splitting the atom using a particle accelerator, and Appleton for demonstrating the existence of the ionosphere. He was admitted to the Order of Merit in 1925 and in 1931 was created Baron Rutherford of Nelson, of Cambridge in the County of Cambridge, a title that became extinct upon his unexpected death in hospital following an operation for an umbilical hernia (1937). Since he was a peer, British protocol at that time required that he be operated on by a titled doctor, and the delay cost him his life. He is interred in Westminster Abbey, alongside J. J. Thomson, and near Sir Isaac Newton.

Legacy

Rutherford's research, along with that of his protégé Sir Mark Oliphant, was instrumental in the convening of the Manhattan Project to develop the first nuclear weapons.

Many items bear Rutherford's name in honour of his life and work:

  • The crater Rutherford on the Moon, and the crater Rutherford on Mars
  • The Rutherford Award at Thomas Carr College for excellence in VCE Chemistry, Australia
  • Image on New Zealand $100 note.
  • Rutherford was the subject of a play by Stuart Hoar.
  • On the side of the Mond Laboratory on the site of the original Cavendish Laboratory in Cambridge, there is an engraving in Rutherford's memory in the form of a crocodile, this being the nickname given to him by its commissioner, his colleague Peter Kapitza. The initials of the engraver, Eric Gill, are visible within the mouth.
  • The Rutherford Foundation, a charitable trust set up by the Royal Society of New Zealand to support research in science and technology.
