I was in a bookstore and was reading a book about a man that lived about a century ago or longer and was fluent in over 70 languages. This man, whose name I forget, would be able to learn a language he had never heard before within a week. The book was apparently going to speculatively break down how he was able to do this. I didn't buy the book as I was just killing time, but I'd really like to find this book again. Kind of an anticlimactic story I suppose, and a little bit of a Hail Mary to anyone that knows what book I'm talking about.

Cheers!
