Born in [http://en.wikipedia.org/wiki/Lucknow Lucknow], [http://en.wikipedia.org/wiki/India India] to Rev. Joseph & Sarah Jane (Lauck) Parson, Alfred received his BS in chemistry from Oxford University. Between 1913 and 1915 he was a visiting graduate student at Harvard and the University of California, Berkeley, where coincidentally [http://en.wikipedia.org/wiki/Gilbert_N._Lewis Gilbert N. Lewis] was working as the chair of the department of chemistry. During these years, [http://en.wikipedia.org/wiki/Gilbert_N._Lewis Lewis] read a paper by Parson, which argued that the electron, in the [http://en.wikipedia.org/wiki/Bohr_model Bohr model], might be a ring of negative electricity spinning with a high velocity about its axis and that a chemical bond results from two electrons being shared between two atoms. Parson published the final draft of his theory in 1915.[http://en.wikipedia.org/wiki/Alfred_Lauck_Parson#cite_note-magneton-0 [1]] Stimulated by this paper, [http://en.wikipedia.org/wiki/Gilbert_N._Lewis Lewis] published his famous 1916 article "[http://dbhs.wvusd.k12.ca.us/webdocs/Chem-History/Lewis-1916/Lewis-1916.html The Atom and the Molecule]", in which a chemical bond forms owing to the sharing of pairs of electrons.[http://en.wikipedia.org/wiki/Alfred_Lauck_Parson#cite_note-1 [2]] Several other physicists of the time, including [http://en.wikipedia.org/wiki/Arthur_H._Compton Arthur H. Compton], [http://en.wikipedia.org/wiki/Clinton_Davisson Clinton Davisson], Lars O. Grondahl, [http://en.wikipedia.org/wiki/David_L._Webster David L. Webster],[http://en.wikipedia.org/wiki/Alfred_Lauck_Parson#cite_note-2 [3]] and [http://en.wikipedia.org/wiki/H._Stanley_Allen H. Stanley Allen], developed the [http://en.wikipedia.org/wiki/Toroidal_ring_model Parson magneton] further using a [http://en.wikipedia.org/wiki/Toroidal_ring_model toroidal ring model] for the atom. Parson himself returned to England, where he served in World War I. Suffering from severe shell shock, he did not pursue an academic career, but years later published papers and books on astronomy and related topics. He died 1970 in Allonby, England.
