Alfred Lauck Parson (October 24, 1889 – January 1, 1970) was a British chemist and physicist, whose "magneton theory" of the atom contributed to the history of chemistry.
Born in Lucknow, 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 Gilbert N. Lewis was working as the chair of the department of chemistry. During these years, Lewis read a paper by Parson, which argued that the electron, in the 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. Stimulated by this paper, Lewis published his famous 1916 article "The Atom and the Molecule", in which a chemical bond forms owing to the sharing of pairs of electrons. Several other physicists of the time, including Arthur H. Compton, Clinton Davisson, Lars O. Grondahl, David L. Webster, and H. Stanley Allen, developed Parson's ideas further using a toroidal ring model for the atom.
