“For most of his life, Thomas Jefferson was obsessed with mammoths. (More correctly, he was obsessed with American mastodons, tree-chewing cousins of mammoths that lived in the Northern part of the continent—but at the time, he and the rest of the world thought they were mammoths.) He liked theorizing about mammoths, he liked talking about mammoths, he liked making his friends rack up exorbitant postage bills in order to mail him mammoth teeth. And for decades, from the mid-1760s onward, he was particularly dedicated to one surprisingly high-stakes activity—convincing a famous French naturalist that mammoths were still out there, tearing up the wild West with their tusks.”
I had no idea.
