Not sure, but "eingebröselte" is a typical North-German word - that wouldn't be applied in South-Germany, Switzerland or Austria
The likely best and authentic kitchen in German speaking areas IMO is Elsass (Alsace) and their Schnitzel are fantastic - looking at some timelines e.g. Wienerschnitzel around 1845, Cordon Bleu (The bread crumb idea in Alsace) 1760 - I would assume that the Paniertes (breadcrumb) Schnitzel drives from Alsace and then spread through Schwitzerland - Baden - Bavaria - Austria, then into Germany and Europe.(Thanks to Napoleon) Whilst in Bavaria and Baden additional variants were created - like Jägerschnitzel, Zigeuner, Holzfäller, Altbayrisch and e.g. Nackerts Schnitzel.
