Beethoven was born in 1770 in Germany and showed early musical talent, though he had an abusive father who forced him to practice for hours. He moved to Vienna in his early 20s where he met and impressed Mozart, though was never able to formally study with him. Beethoven went deaf in his 30s but continued composing profoundly, including his famous 9th Symphony. Though ill-tempered and eccentric, Beethoven was considered a musical genius and revolutionized classical music with his innovative and emotional compositions.
