Johann Adolf Hasse

Johann Adolph Hasse was an 18th-century German composer, singer and teacher of music. Immensely popular in his time, Hasse was best known for his prolific operatic output, though he also composed a considerable quantity of sacred music. Married to soprano Faustina Bordoni and a friend of librettist Pietro Metastasio, whose libretti he frequently set, Hasse was a pivotal figure in the development of opera seria and 18th-century music.
