 And now it's time to turn to our Living on Earth contributor, Peter Dykstra. He's got a few stories from the history books that we're going to take a look at now. Hey, Peter, what do you have for me this week? Hi, Ainsley. The first one comes on July 12, 1817, which was the birth date of Henry David Thoreau. That's the way it apparently was pronounced back in the 19th century, even though we say Thoreau these days.
