Beethoven surely was an interesting character. He often had trouble finding apartments because he was such a difficult neighbor (and it didn't help that he played his piano as loud as possible, so that he could hear it). One time, he was arrested because he was creeping around Wiener Neustadt at night, dressed like a beggar, and peeping into living rooms. Nobody believed he was the famous composer, and a local organist had to be brought in to identify Beethoven. He also fought a long violent legal battle for custody of his nephew Karl after the death of his brother (Beethoven hated his sister-in-law) which lead to a suicide attempt of Karl, and the break-off of all contact. His sister-in-law in turn told the authorities that the "van" in Beethovens surname had nothing to do with nobility (as he seemingly had claimed), but was just a normal surname in in the Flemish region of his ancestors. What I also find highly fascinating are the entries in his conversation books which document how relatives tried to teach him basic math. It's strange to see that one of greatest composers in human history was unable to grasp multiplication or division.
