Albert of Brunswick-Grubenhagen
Albert of Brunswick-Grubenhagen (c. 1284 – after 1341) was a son of Duke Henry I “the Miraculous” of Brunswick-Grubenhagen and Agnes of Meissen, and a nephew of the Teutonic Order's grand master Luther von Braunschweig.
He is documented as a professed knight of the Order from 1320/21, served as Komtur of Mewe on the Vistula in 1332/33, and rose to Landkomtur, holding that rank in Prussia and in 1335–1338 in the Ballei an der Etsch, the Order's bailiwick in the Tyrolean Adige valley.
