Ernest Rutherford Death and Legacy


Death and Legacy

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, the Large Hadron Collider started smashing atomic particles in May 2010. It has since been used to answer fundamental questions about physics, by scientists who share in Rutherford’s tendency toward forward-thinking and his relentless quest for proof through scientific exploration.

Ernest Rutherford Research and Discoveries



Research and Discoveries

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
of gases, resulting in a paper about dividing atoms and molecules into ions. While Thomson went on to examine what would later be called an electron, Rutherford took a closer look at ion-producing radiations.
Focusing on uranium, Rutherford discovered that placing it near foil resulted in one type of radiation being easily soaked up or blocked, while a different type had no trouble penetrating the same foil. He labeled the two radiation types “alpha” and “beta.” As it turns out, the alpha particle was identical to the nucleus of a helium atom. The beta particle was, in fact, the same as an electron or positron.
Rutherford left Cambridge in 1902 and took up a professorship at McGill University in Montreal.
