In 1898, a pair of lions known as the Tsavo Man-Eaters temporarily put a massive British railway project in Kenya on hold when they began pulling workers from their tents at night. Accounts vary as to the total number of victims, with some going as high as 135, although scientific tests conducted by the Chicago Field Museum, which has the taxidermied lions on display, has indicated that they probably didn’t actually consume more than thirty-five of their victims.
