I feel stupider for reading through this. Hemingway loved whisky, but also extreme sport adventures: he said "Only three real sports exist: bullfighting, motor racing, mountaineering; the rest are just games". Edison lamp was not even the most efficient of its *decade*, it was just cheap and well marketed. Marie Antoinette never said the "cake" phrase. And so on. It looks written by someone who know the characters just by a cursory Wikipedia reading.
