Anton Schindler
Ludwig van Beethoven's 1802 Piano Sonata No. 17 in D minor, Op. 31, No. 2, was given the subtitle "The Tempest" some time after Beethoven's death because, when asked about the meaning of the sonata, Beethoven was alleged to have said "Read "The Tempest"". But this story comes from his associate Anton Schindler, who is often not trustworthy.
