Martín de Porres was born in Lima. There are two versions of his early life.
In one, he was the son of an unknown father and a free African-Peruvian mother, adopted when he was eight by a Spanish nobleman.
According to another story, his father was a Spanish nobleman who abandoned his mother, Martín and his sister because of their color, but returned when Martín was 15 to help support them.
Martín was trained as a barber-surgeon, and entered a Dominican monastery as a lay helper. Nine years later he joined the order officially. He was canonized in 1962 by Pope John XXIII because of his great purity and his love for all people, and is the patron saint of social action.
