Sergio Rubin is an Argentine journalist. He is the authorized biographer of Pope Francis, and wrote his only biography available at the time of his election, in March, 2013.
Rubin met Jorge Bergoglio in the 1990s, while conducting interviews with the Archbishop Antonio Quarracino. He wrote El jesuita, the first biography of Jorge Bergoglio, in 2010. Along with Italian journalist Francesca Ambrogetti, he decided to write the biography when Bergoglio got 40 votes at the 2005 Papal conclave, the highest number of votes ever obtained by a Latin American papabile.
He attended the 2013 Papal conclave along with 5,600 other journalists. Bergoglio was elected as Pope, and as his biographer, Rubin suddenly became highly requested for interviews by several international media.
