During the summer of 1965, an informal seminar in geometric topology was held at the University of Wisconsin under the direction of Professor Bing. Twenty-five of these lectures are included in this study, among them Professor Bing’s lecture describing the recent attacks of Haken and Poincaré on the Poincaré conjectures, and sketching a proof of Haken’s main result.
