Blessed Albert Berdini of Sarteano was a Franciscan Friar and missionary, born in Tuscany in 1385. He entered the order of Minor Conventuals in 1405, but later, attracted by St. Bernardine of Siena, whose fame was spread throughout Italy, and desirous of following more strictly the rule of St. Francis, he passed over to the Friars Minor and became one of the companions of the great Apostle of the Holy Name.
Under the masterful guidance of St. Bernardine his fame as an orator became so renowned that he was commonly known as the "King of Preachers" (Rex Praedicatorum); Pope Eugene IV commissioned him as one of his legates to negotiate with Greek schismatics and induce them to be present at the council held in Bologna in 1453.
Though the title of Blessed has always been accorded to Albert of Sarteano, principally on account of the fact, as one of the earlier chroniclers of the order tell us, of the numerous miracles he worked after his death at Milan, his cultus has never been explicitly approved by the Catholic Church. Active steps have, however, been taken for his formal beatification.
