“The text is well written. It contains a wealth of material previously published in several books and articles. An extended bibliography makes it possible to access the original references. As a final note, the book also contains a number of historical pictures of some of the main mathematicians related to the topics described.”  (Alessandro Perotti, Mathematical Reviews, July, 2017)
