Jakob Meyer zum Hasen (1482 in Basel – 1531 in Freiburg im Breisgau) was the bürgermeister of the city of Basel from 1516 to 1521. A money changer by profession, he was the first bürgermeister of Basel to be a tradesman, belonging to a guild[1] rather than a member of the aristocracy or a wealthy family. He is known as a patron of the painter Hans Holbein the Younger, having commissioned the Darmstadt Madonna and a double portrait from him.[2]
