The facade of the Our Lady of Mercy college in the Flores neighborhood in Buenos Aires, where Jorge Mario Bergoglio, elected on the eve as Pope Francis, went as a child in the kindergarten, on March 14, 2013. Bergoglio, chosen Wednesday to lead the world's Roman Catholics, is a humble rail worker's son who became a Jesuit priest and who is seen as true to his working-class roots.AFP PHOTO / ALEJANDRO PAGNI
