# John H. Smith

**John H. Smith** was responsible for defining the "Smith set" (among other accomplishments).

John Howard Smithis an American mathematician and retired professor of mathematics at Boston College.^{[1]}He received his Ph.D. from the Massachusetts Institute of Technology in 1963, under the supervision of Kenkichi Iwasawa.^{[1]}^{[2]}In voting theory, he is known for the Smith set, the smallest nonempty set of candidates such that, in every pairwise matchup (two-candidate election/runoff) between a member and a non-member, the member is the winner by majority rule, and for the Smith criterion, a property of certain election systems in which the winner is guaranteed to belong to the Smith set.

^{[3]}He has also made contributions to spectral graph theory^{[4]}and additive number theory.^{[5]}
