# A Generalization of Wilson’s Theorem (due to Gauss)

John Wilson (1741-1793) was a well-known English mathematician in his time, whose legacy lives on in his eponymous result, Wilson’s Theorem.

In this post, we’ll generalize Wison’s Theorem to non-prime modulus (and a few other generalizations) and give credit to Gauss for beating us to it by two hundred years.
