Research assistant Ernst Ziegler is an Helga's archeology team member mentioned in Gottfried Winkler's note in Wolfenstein: The Old Blood.
On 28 February 1946 he was burned to death while performing an experiment on object #12-1 from the Wulfburg dig. His death forced Gottfried Winkler to wrote a letter to Ziegler's wife and to improve safety procedures before continuing experiments with the object.
