Borosini created numerous leading roles in the operas of Francesco Bartolomeo Conti and Johann Joseph Fux at the imperial court in Vienna and was the first great Italian tenor to appear in London.
[1][2] Borosini was born in Modena and was schooled in singing by his father, Antonio Borosini, a tenor and composer active in Venice and Modena who later became a singer at the imperial court in Vienna.
Francesco is thought to have made his debut in 1709 in Venice singing in Antonio Lotti's Il vincitor generoso.
Like his father, he was appointed as a singer to the Viennese imperial court and performed there from 1711 until 1731 with intermittent sojourns to Italy and London where he worked closely with Handel.
He created the role of Bajazet in Handel's Tamerlano, one of several which the composer wrote or rewrote expressly for Borosini's voice.
