Josef Groll (21 August 1813, Vilshofen an der Donau – 22 November 1887, Vilshofen) was a Bavarian brewer, best known for being the first brewer of Pilsner beer.
He is sometimes called "the Father of the Pilsner".
The world's first-ever pale lager, Pilsner Urquell was highly successful, and served as the inspiration for more than two-thirds of the beer produced in the world today.
