scientist and doctor. Born of a noble Beneventan family, he showed extraordinary promise as a student at Naples University, where he joined the medical faculty and came to be reckoned a precursor of modern biochemistry. His religious commitment was shown in both a vow of chastity and whole-hearted care of incurables at Santa Maria del Populo. The eruption of Vesuvius in 1906 and an outbreak of cholera in 1911 proved his charity still further. His scientific research continued, he exercised his medical profession to relieve suffering, not to make profits, and he used to retire regularly for long periods of prayer. Three years after his death his relics were translated to the church of Gesu Nuovo. He was beatified in 1975 and canonized in 1987. Feast. 16 November.
