Bibiana Steinhaus became the first woman to referee a men's match in one of Europe's biggest leagues when she was the main referee in 2017 in the Bundesliga meeting between Hertha Berlin and Werder Bremen.
Yesterday, the final of the German Super Cup was played between Bayern Munich and Borussia Dortmund.
Bayern won the match 3-2.
That match was Steinhaus' last in his career.
Earlier yesterday, she had revealed that she does not intend to continue refereeing football.
- I will tell you about the reason in the future, she says to the German Football Association's website.
On a daily basis, Steinhaus works as a police officer.
