Beethoven had many problems when his brother Caspar Carl died, leaving a 9-year-old son. The boy’s mother may have been incapable of looking after him, but Beethoven had to prove this in a court of law. For several years he looked after his nephew, but it was a difficult relationship and it involved a lot of legal letters and quarrels with people. In 1826, Karl tried to shoot himself. He survived, but people persuaded Beethoven to stop being his guardian. Karl went into the army.
