Born in Naples, Porpora's first major professional appointment was as Kapellmeister to the Landgrave of Hesse-Darmstadt from 1711-1725, during which time he taught Hasse. In 1733 Porpora moved to London where for the next three years he competed with Handel as composer of operas for the English royals. Following his London sojourn Porpora returned to Italy alternating time between Naples and Venice where he taught voice. In 1747 Porpora became singing teacher to the Electoral Princess in Dresden and in 1751 he moved to Vienna where he taught Haydn. Porpora composed 50 operas, chamber music, violin sonatas, Masses, motets, oratorios, and cantatas.
