Martin de Porres Velázquez, O.P. (December 9, 1579 – November 3, 1639), was a lay brother of the Dominican Order who was beatified in 1837 by Pope Gregory XVI and canonised in 1962 by Pope John XXIII. He is the patron saint of mixed-race people, barbers, innkeepers, public health workers, and all those seeking racial harmony. He was noted for work on behalf of the poor, establishing an orphanage and a children's hospital. He maintained an austere lifestyle, which included fasting and abstaining from meat. Among the many miracles attributed to him were those of levitation, bilocation, miraculous knowledge, instantaneous cures, and an ability to communicate with animals.
