a Roman Catholic prelate of Austria, was born April 6, 1811, at Partheuen. In 1853 he was made bishop of Linz, and died November 24, 1884. Ridiger was one of those prelates who opposed all measures of the Austrian government which tended towards depriving the Church of any of her prerogatives. Riidiger only knew one government, the supremacy of the Church. When the dogma, of the Immaculate Conception was proclaimed he celebrated that event by building a splendid cathedral at Linz, and erecting monasteries throughout his diocese. (B.P.)
