Konrad von Dürrach
Konrad von Dürrach was Schultheiss (chief magistrate) of the imperial city of Solothurn in 1328/29–1333/34 and again in 1336/37–1339/40, when the office was a pawned imperial fief before passing to election by the citizenry around 1344. Other members of the Dürrach family held the same office down to 1411 and led the city's pro-Bern party.
During Konrad's second tenure Solothurn troops marched in Bern's relief army and fought at Laupen on 21 June 1339, when the allies raised the eleven-day siege by the army of Freiburg, the bishop of Basel and the Burgundian lords.
