Aston, Francis William Francis William Aston was born in September 1877 at Harborne, Birmingham, England, the third of a family of seven children. He was educated at Harborne Vicarage School and Malvern College where his interest in science was aroused. In 1894 he entered Mason College, Birmingham (later to become the University of Birmingham) where he studied chemistry under Frankland and Tilden, and Physics under Poynting. His winning of the Forster Scholarship in 1898 enabled him to work on the optical properties of tartaric acid derivatives; the results of this work were published in 1901. Leaving academic life for a time, he worked for three years as a chemist in the laboratory of a brewery. At about this time, however, his interest in physics, rather than chemistry, began to predominate; his aptitude for mechanical contrivance showed itself in his design and construction of new types of pumps for evacuating vessels. From this stemmed his interest in gas discharge phenomena in evacuated tubes. In 1903 he obtained a scholarship to Birmingham University (as it had now become) to work on the properties of the Crookes Dark Space in discharge tubes. Within a short time he had discovered the phenomenon which is known as the Aston Dark Space. At the end of 1909 he accepted the invitation of Sir J.J.Thomson to work as his assistant at the Cavendish Laboratory, Cambridge, on studies of positive rays. It was during this period that he obtained definite evidence for the existence of two isotopes of the inert gas neon.

Francis William Aston (1877-1945) Francis William Aston, an experimental physicist, was born in Harborne, England, in September 1st 1877, and died in Cambridge, in November 20th 1945. He worked with Frankland in 1898, with Poynting in 1903, and with J.J Thomson in 1910. He had enormous experience in vacuum techniques what made possible the evidence of the isotopic constitution of a stable element. In 1913 he accomplished the partial separation of isotopes by the diffusion method. In 1922 he received the Nobel Prize of Chemistry. His work is explained in his book Mass Spectra and Isotopes

Trabalhou com Frankland em 1898, Poynting em 1903 e J.J Thomson em 1910. A sua larga experiência em técnicas de vácuo permitiu-lhe pôr em evidência pela primeira vez a constituição isotópica de um elemento estável por meio de análise dos raios positivos. Em 1913 conseguiu uma separação parcial de isótopos por um método de difusão. Obteve o Prémio Nobel da Química em 1922. Deixou a obra Mass spectra and Isotopes
