Ludwig van Beethoven was taught by his father Johann.
 Beethoven then gained a reputation as a virtuoso pianist, and he was soon patronized by Karl Alois, Prince Lichnowsky for compositions, which resulted in his three Opus 1 piano trios (the earliest works to which he accorded an opus number) in 1795
 His mother died in 1787, shortly after Beethoven's first visit to Vienna, where he stayed for about two weeks and almost certainly met Mozart
