Jorge Mario Bergoglio (fourth boy from the left on the third row from the top) at age 12, while studying at the Salesian College (c. 1948-49)
Jorge Mario Bergoglio was born on 17 December 1936 in Flores, a neighborhood of Buenos Aires. He was the eldest of five children of Mario José Bergoglio (1908–1959) and Regina María Sívori (1911–1981). Mario Bergoglio was an Italian immigrant accountant born in Portacomaro (Province of Asti) in Italy's Piedmont region. Regina Sívori was a housewife born in Buenos Aires to a family of northern Italian (Piedmontese-Genoese) origin. Mario José's family left Italy in 1929 to escape the fascist rule of Benito Mussolini. According to María Elena Bergoglio (b. 7 February 1948), the Pope's only living sibling, they did not emigrate for economic reasons. His other siblings were Alberto Horacio (17 July 1942 – 15 June 2010), Oscar Adrián (30 January 1938-deceased) and Marta Regina (24 August 1940 – 11 July 2007). Two great-nephews, Antonio and Joseph, died in a traffic collision.
In the sixth grade, Bergoglio attended Wilfrid Barón de los Santos Ángeles, a school of the Salesians of Don Bosco, in Ramos Mejía, Buenos Aires. He attended the technical secondary school Escuela Técnica Industrial N° 27 Hipólito Yrigoyen, named after a past President of Argentina, and graduated with a chemical technician's diploma. He worked for a few years in that capacity in the foods section at Hickethier-Bachmann Laboratory where his boss was Esther Ballestrino. Before joining the Jesuits, Bergoglio worked as a bar bouncer and as a janitor sweeping floors, and he also ran tests in a chemical laboratory. Bergoglio was initially stated in media reports to having obtained a master's degree in Chemistry, although this was later determined to be false.
In the only known health crisis of his youth, at the age of 21 he suffered from life-threatening pneumonia and three cysts. He had part of a lung excised shortly afterwards. Bergoglio has been a lifelong supporter of San Lorenzo de Almagro club. Bergoglio is also a fan of the films of Tita Merello, neorealism, and tango dancing, with a fondness for the traditional music of Argentina and Uruguay known as the milonga.
