Founder of the Redemptorists, born at Naples of a noble family; bred to the law, but devoted himself to a religious life, received holy orders, lived a life of austerity, and gave himself up to reclaim the lost and instruct the poor and ignorant; was a man of extensive learning, and found time from his pastoral labours to contribute extensively to theological literature and chiefly casuistry, to the extent of 70 volumes; was canonised in 1839; the order he founded is called by his own name as well (1696-1787).
