Johannes Baptist Franzelin (b. at Aldein, in Tyrol, 15 April 1816; d. at Rome, 11 December 1886) was an Austrian Jesuit theologian and Cardinal.
In 1850, he returned to the Roman college as assistant professor of dogma and lecturer on Arabic, Syriac, and Chaldean.
As a cardinal, his sole departure from strict adherence to the Jesuit rule was to omit the daily recreation.
His entire income as cardinal he distributed among the poor, the foreign missions, and converts whose property had been seized by the Italian government.
[1] From the first his works were recognized as a mine of rich material for the preacher; and for years he was accustomed to receive numerous letters from priests in all parts of the world, spontaneously acknowledging the great aid in preaching they had derived from his books.
