Saint Alphonsus Liguori was a great moral theologian as well as the founder of the Redemptorists.  Unlike most of the young men of his day, he did not pursue a military career because he had asthma and horrible eyesight.  So he studied.  And studied.  The man became a lawyer when he was still a teenager. He never lost a case for almost 10 years, until one day he did lose a case. He then said, “The heck with this,” and went to seminary.  He wanted to become an Oratorian (YES!!!), but his father wouldn’t have it. They compromised and he became a parish priest.  His preaching was incredible — he said he’d never preach a homily the poorest peasant couldn’t understand.  Eventually God led him to found a new order, the Congregation of the Most Holy Redeemer.  Cardinal Tobin is a member of this order of course, and he was the pastor of the Church of St. Alphonsus Liguori in Rome before he became a bishop.  The original Our Lady of Perpetual Help icon is there.
