Person: Wilson (2), John
John Wilson is best known for Wilson's theorem: If $p$ is prime then $1 + (p  1)!$ is divisible by $p$.
Mathematical Profile (Excerpt):
 Before he took his final examinations Wilson had already gained a strong reputation and he had also attracted considerable attention by defending Waring, who was the Lucasian Professor of Mathematics, from strong attacks which had been made on him as a result of his text Miscellanea analytica Ⓣ(Miscellaneous analysis).
 On 7 July 1764 Wilson was elected a Fellow of Peterhouse and he taught mathematics at Cambridge with great skill, quickly gaining an outstanding reputation for himself.
 Almost certainly Wilson's theorem was a guess made by him, based on the evidence of a number of special cases, which neither he nor Waring knew how to prove.
 Almost certainly Wilson's interest in mathematics continued during his legal career for he was elected a fellow of the Royal Society on 13 March 1782.
 At the time that Wilson served on this body it was one of three courts which dealt with commonlaw business.
 The marriage, however, was not to be a long one for Wilson died only five years after his marriage.
Born 6 August 1741, Applethwaite, Westmoreland, England. Died 18 October 1793, Kendal, Westmoreland, England.
