Slightly off topic but I always found it interesting and, being a Romanov fan, heartening, to hear that Frenchwoman Jeanne Calment, the longest living person ever recorded (1875-1997) considered the execution of the Russian Imperial Family to be the most significant historical event in her lifetime.
This is someone who met Vincent Van Gogh, saw the invention of electricity, the automobile and airplane, lived through two World Wars and was still around when the World-Wide Web was first launched...and yet it was the death of the Romanovs that stood out above all else. Pretty impressive!
