NPR book critic Glen Weldon, author of Superman: The Unauthorized Biography, has created a witty, intelligent cultural history of Batman's popularity through the ages, and what his story tells us about ourselves. Thurber House is pleased to host Weldon to discuss his new book, The Caped Crusade. Since his creation, Batman has been a two-fisted detective; a planet-hopping gadabout; a campy pop-art sensation; a pointy-eared master spy; and a grim and gritty ninja of the urban night. He has cycled from a figure of darkness to one of lightness and back again. It's this endlessly mutable quality that has made him so enduring. And, Batman's fundamental nerdiness - his gadgets, his oath, even his lack of superpowers - resonates with fans who are fiercely protective of him. With humor and insight, Weldon lays out Batman's 78-year cultural history and shows why his legacy remains so strong.
