Saint Peter Tuan P.M. (†1838) - was Catholic martyr of Vietnam. A native priest, he was arrested by Vietnamese authorities and suffered such grievous tortures while in prison that he died before they could carry out the order of execution by beheading. Pope John Paul II canonized him in 1988, as part of the group of 117 Vietnamese martyrs. His feast day is celebrated on July 15th.
