The Twelfth Doctor used the hypothetical non-existence of Beethoven in a story (which didn't happen) as an example of the "Bootstrap paradox", where a time traveller travelled back to 18th century Germany and copied out the concertos and symphonies he had brought with him and got them published after finding out no-one knew who Beethoven was, the time traveller essentially becoming Beethoven. He described Beethoven as a "[n]ice chap, very intense," and that he "[l]oved an arm wrestle." (TV: Before the Flood)
