1920: Bizarre royal death of the year: that of Alexander, king of the Hellenes. On 2 October, the king and his dog Fritz encountered two pet monkeys playing in a garden on the royal estate at Tatoi, near Athens. The monkeys scampered over, screaming, and one of them attacked Fritz. The king tried to separate the animals, whereupon the second monkey intervened, and in the ensuing scrimmage the king was severely bitten on the legs and belly. The wounds were not properly cleaned, infection set in, and on 25 October the king died of sepsis.
