1417

The Münchner Brauhaus on the corner of Sendlinger- and Hackerstreet mentioned in 1417 as the first place where Hacker beer is brewed. Today we find the "Alte Hackerhaus" (old Hacker house) at the place where the beer was once brewed.

1781

Peter Paul Hacker takes over the Hacker brewery from his father Simon Hacker, who had been leading the company since 1738.

1793

The 23-year-old farmer’s son Josef Pschorr, who had been working as a brew laborer, marries Therese Hacker, the daughter of his "brew master" (the owner of the brewery) and buys the brewery from his father-in-law. In the following 15 years, the small Hacker Brewery becomes Munich's top brewery among the 50 existing Munich breweries, due to the hard work and skill of Josef Pschorr.
