Joseph Haydn
After he was released from his duties with the Esterhazys, Haydn travelled to London. Even at the age of 60 he was still active and wrote some of his most famous symphonies there. While in London, he heard Handel's Messiah, and was inspired to write two oratorios of his own, The Seasons and The Creation. While working on these oratorios in Vienna, Haydn gave lessons to Ludwig van Beethoven. Beethoven had first wanted to study with Mozart, but by the time Beethoven was ready to study in Vienna, Mozart had died.
