After the devastating conflict that was the Civil War, Americans began craving renewed contact with the natural world. One way this craving manifested itself as a national obsession with butterflies and craze for butterfly collection. Tune in this Thursday at 9PM for a conversation with Professor William Leach, author of the new book The Butterfly People: an American Encounter with the Beauty of the World, in which he chronicles the lives of the scientists and passionate amatuer collecters that formed the "butterfly movement" of the mid 19th century. In this interview Professor Leach discusses the book, his own childhood experience with butterfly collecting, and the ways in which people today can reconnect with the richness of the natural world.
