Most Rev. Boniface Krug, O.S.B., S.T.D., was a student at St. Vincent's from 1849-1856. He went to Rome to study, transferred his vows to Monte Cassino Abbey, and in 1888 became its Abbot-Ordinary. Before his death, in 1909, he had become known as the great rebuilder of the modern Monte Cassino. It was Abbot Boniface who entertained the American poet Longfellow on his visit to Monte Cassino and Longfellow pays tribute to him in his poem "Monte Cassino."
