# Wilson's Theorem/Generalization/Historical Note

This generalization of Wilson's theorem was demonstrated, according to Donald E. Knuth: The Art of Computer Programming: Volume 1: Fundamental Algorithms (3rd ed.), by Ludwig Stickelberger in $1890$.
It is supposed that this appears in Stickelberger's $1890$ article Ueber eine Verallgemeinerung der Kreistheilung (Math. Ann. Vol. 37: 321 – 367) during the course of his proof of Stickelberger's Theorem.
