Antonio Salieri was a classical composer, conductor, and teacher born in Italy in 1750. He spent his adult life in the Habsburg monarchy and was a pivotal figure in the development of late 18th-century opera. He helped develop and shape many of the features of operatic compositional vocabulary, and his music was a powerful influence on contemporary composers. Salieri dominated Italian-language opera in Vienna as the director of the Italian opera from 1774 until 1792. He also wrote works for opera houses in Paris, Rome, and Venice, and his dramatic works were widely performed throughout Europe. He was also an influential teacher whose pupils included Franz Liszt, Franz Schubert, Ludwig van Beethoven, and others. Salieri's fame declined after his death but was revived in the late 20th century due to the fictionalized depiction of him in Peter Shaffer's play Amadeus. There were rumors that Salieri had poisoned Wolfgang Amadeus Mozart, but it is likely that they were respectful peers.
