Saint Dominic Savio (†1857) was an Italian student of Saint John Bosco who was noted for his piety and devotion to the Catholic faith and was eventually canonized. He was studying to be a priest when he became ill and died at the age of 14, possibly from pleurisy. Bosco regarded Savio very highly and wrote a biography of his young student, The Life of Dominic Savio. This volume, along with other accounts of him, were critical factors in his cause for sainthood. Despite the fact that many people considered him to have died at too young an age – fourteen – to be considered for sainthood, he was considered eligible for such singular honor on the basis of his having displayed "heroic virtue" in his everyday life. Savio was canonized as a saint in 1954, by Pope Pius XII, making him the youngest non-martyr to be canonized in the Catholic Church. He is considered a patron saint of choirboys, falsely accused people, and juvenile delinquents. His feast day is celebrated on 6 May.
