Ernest Rutherford, 1st Baron Rutherford of Nelson, OM, PC, FRS (30 August 1871 – 19 October 1937) was a
New Zealand physicistwho became known as the father of nuclear physics. He pioneered the orbital theory of the atomthrough his discovery of Rutherford scatteringoff the nucleus with his gold foil experiment. He was awarded the Nobel Prize in Chemistryin 1908.
Ernest Rutherford was the son of James Rutherford, a farmer, and his wife Martha (born Thompson, originally from
Hornchurch, Essex, England).

Ernest was born at Spring Grove (now Brightwater), near Nelson, New Zealand. His first name was mistakenly spelt "Earnest" when his birth was registered.

After gaining his BA, MA and BSc, and doing two years of research at the forefront of electrical technology, in 1895 Rutherford travelled to Englandfor postgraduate study at the Cavendish Laboratory, University of Cambridge(1895–1898), and he briefly held the world record for the distance over which electromagnetic waves could be detected. During the investigation of radioactivityhe coined the terms alpha and beta to describe the two distinct types of radiation emitted by thoriumand uranium.
In 1898 Rutherford was appointed to the chair of physics at
McGill Universityin Montreal, Canada, where he did the work that gained him the Nobel Prize in Chemistryin 1908. In 1900 he gained a DScfrom the University of New Zealand, and from 1900 to 1903 he was joined at McGill by the young Frederick Soddy( Nobel Prize in Chemistry, 1921) and they collaborated on research into the transmutationof elements. Rutherford had demonstrated that radioactivitywas the spontaneous disintegration of atoms. He noticed that a sample of radioactive material invariably took the same amount of time for half the sample to decay – its " half-life" – and created a practical application using this constant rate of decay as a clock, which could then be used to help determine the age of the Earth, which turned out to be much older than most of the scientists at the time believed.
In 1900 he married Mary Georgina Newton (1876-1945); they had one daughter, Eileen Mary (1901-1930), who married
In 1907 Rutherford took the chair of physics at the
University of Manchester. There along with Hans Geigerand Ernest Marsdenhe carried out the Geiger-Marsden experiment, which demonstrated the nuclear nature of atoms. It was his interpretation of this experiment that led him to the Rutherford modelof the atom, with a very small positively- charged nucleus orbited by electrons. In 1919 he became the first person to transmute one element into another when he converted nitrogeninto oxygenthrough a nuclear reaction14N(α,p)17O. In 1921, while working with Niels Bohr(who postulated that electrons moved in specific orbits), Rutherford theorized about the existence of neutrons, which could somehow compensate for the repelling effect of the positive charges of protons by causing an attractive nuclear forceand thus keeping the nuclei from breaking apart. Rutherford's theory of neutrons was proved in 1932 by his associate James Chadwick, who in 1935 was awarded the Nobel Prize in Physics for this discovery.
He was knighted in 1914. 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 required that he be operated on by a titled doctor, and the delay cost him his life. [cite web | author=D.A.

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