Ernest Rutherford Biography (Atomic Theory)


Posted: 11 Jun 2012 07:51 AM PDT
Chemist and physicist Ernest Rutherford was born August 30, 1871, in Spring Grove, New Zealand. A pioneer of nuclear physics and the first to split the atom, Rutherford was awarded the 1908 Nobel Prize in Chemistry for his theory of atomic structure. Dubbed the “Father of the Nuclear Age,” Rutherford died in Cambridge, England, on October 19, 1937 of a strangulated hernia.
In 1895, as the first research student at the University of Cambridge’s Cavendish Laboratory in London, Rutherford identified a simpler and more commercially viable means of detecting radio waves than had been previously established by German physicist Heinrich Hertz.
Also while at Cavendish Laboratory, Rutherford was invited by Professor J.J. Thomson to collaborate on a study of X-rays. German physicist Wilhelm Conrad Röntgen had discovered X-rays just months before Rutherford arrived at Cavendish, and X-rays were a hot topic among research scientists. Together, Rutherford and Thomson studied the effects of X-rays on the conductivity of gases, resulting in a paper about dividing atoms and molecules into ions. While Thomson went on to examine what would
Rutherford was awarded with countless honors during his career, including several honorary degrees and fellowships from organizations such as the Institution of Electrical Engineers. In 1914 he was knighted. In 1931, he was elevated to the peerage, and granted the title Baron Rutherford of Nelson. He was also elected president of the Institute of Physics that same year.
On October 19, 1937, Baron Rutherford died in Cambridge, England at age 66 from the complications of a strangulated hernia. The scientist, who had been nicknamed “Crocodile” by his colleagues for always looking ahead, was buried at Westminster Abbey.
Years before he died, during World War I, Rutherford said he hoped scientists would not learn how to extract atomic energy until “man was living at peace with his neighbors.” The discovery of nuclear fission was, in fact, made just two years after his death, and eventually resulted in what Rutherford had feared—the use of nuclear power to build wartime weapons.
Many of Rutherford’s discoveries also became the basis of the European Organization for Nuclear Research’s construction of the Large Hadron Collider. The largest and highest-energy particle accelerator in the world and decades in the making,
