1995 marked the 50th anniversary of Stefan Banach's death. Until now, the general English speaking public has had no access to an in-depth life story of a mathematician whose name is one of those most often encountered in modern mathematical research. This small volume, originally written in Polish by a well-known reporter, is an effort to fill that gap in the biographical literature. It is based on original archival sources, dozens of interviews with people who knew and remember Banach, and conversations with mathematicians who are familiar with Banach's work and its impact on modern mathematics. The author presents engaging descriptions of Banach's personality and the unusual milieu in which he worked. Further, Chapter V focuses on the famous Scottish cafe, which like Banach himself, has achieved a mythical dimension in mathematical lore. The English edition has been revised to include new materials and many photographs, and to reflect the interests of a broader international audience."
