Saint Giuseppe Moscati (†1927) was an Italian doctor, scientific researcher, and university professor noted both for his pioneering work in biochemistry and for his piety. Moscati remained true to his faith his entire life, taking a vow of chastity and practicing charity in his daily work. He viewed his practice of medical science as a way of alleviating suffering, not as a way of making profits, and would retire regularly for prayer. He attended Mass daily, and would sometimes use a patient's faith, as well as the sacraments, in his treatments. He refused to charge the poor for their treatment and was known to sometimes send a patient home with a prescription and money in an envelope. Moscati was canonized by the Catholic Church in 1987; his feast day is 16 November.
