The work of Ludwig van Beethoven (1770-1827) has been called the culmination of the Classical era or the wellspring of the Romantic era in European music. Historians today see him as the heir of Haydn and Mozart, carrying their musical discoveries to a new level of complexity and integration. But the generations of composers that followed Beethoven saw him more as the headstrong radical, breaking the shackles of classicism and showing new possibilities for music.
