Why: the translator described it this way: There's a novel by Robert Löhr called The Secrets of the Chess Machine about the famous chess-playing automaton that caused a sensation at the court of Maria Theresa. Löhr's flight of fancy is that there was a dwarf who supposedly operated the machinery. It's a very funny book, and I spent a lot of my time trying to persuade the English-speaking public that, contrary to popular opinion, the Germans do have a sense of humour.
