János Scheffler

János Scheffler (29 October 1887 – 6 December 1952) was a Hungarian-born Roman Catholic prelate who served as the bishop of two dioceses before acting as the Bishop of Oradea Mare. He was imprisoned due to opposing the Communist government policies and was killed while imprisoned. He had been noted during his episcopate for his attentiveness to vocations and for the defense of the faith from those forces that sought to disrupt it such as communism.
