This is not merely a great book. It is an important piece of chess history, because the author, Hans Kmoch, visited the Rubinstein Family Home in 1933 in an effort to get the great grandmaster of chess to return to active play. When Rubinstein could not be induced to return, his family who was living in dire poverty asked Kmoch for help in raising funds. The result was an ad placed asking to finance this book on a subscription basis. The result was this book.
