Born in Buenos Aires, Argentina, as a young man Bergoglio worked for a time as a bouncer and a janitor before getting training as a chemist, and working as a technician in a food science laboratory. After a recovering from a severe illness, he was inspired to join the Society of Jesus (the Jesuits) in 1958. He was ordained a Catholic priest in 1969, and from 1973 to 1979 was Argentina's provincial superior of the Society of Jesus (Jesuits). He became the archbishop of Buenos Aires in 1998 and was created a cardinal in 2001 by Pope John Paul II. He led the Argentine Church during the December 2001 riots in Argentina. The administrations of Néstor Kirchner and Cristina Fernández de Kirchner considered him a political rival. Following the resignation of Pope Benedict XVI on 28 February 2013, a papal conclave elected Bergoglio as his successor on 13 March. He chose Francis as his papal name in honor of Saint Francis of Assisi. Throughout his public life, Pope Francis has been noted for his humility, emphasis on God's mercy, international visibility as pope, concern for the poor and commitment to interreligious dialogue. He is credited with having a less formal approach to the papacy than his predecessors, for instance choosing to reside in the Domus Sanctae Marthae guesthouse rather than in the papal apartments of the Apostolic Palace used by previous popes.
