Query: A book of personalities

A student of philosophy will find this book interesting for its descriptions of prominent personalities (including Russell), but this book does not contain any particularly profound discussions of philosophy. The ideas of both Wittgenstein and Popper are given a shallow explanations; in addition the basic ideas of some other philosophical schools that came and went are discussed. However, the lives of these men are interesting, and the the author's commentary on the historical importance of the ideas of these men is also interesting. In addition this book gives Wittgenstein fans some helpful information on the evolution of Wittgenstein's ideas that may not be apparent from the paucity of documents that comprise Wittgenstein's writings.
