I enjoyed reading this book. E.T. Bell focuses on the character and story of each person who contributed greatly to the field of Mathematics. The descriptions were for the most part interesting and informative.

I struggled a little with the overall word usage in the book. Also, there were times while reading that I had to skip ahead because the same page put me to sleep more than once.

Overall I enjoyed the read, but would have liked to read more about their specific contributions than the lifestyles each person lived. That not being the author's purpose in writing the piece, I evaluated this book on the first two paragraphs of this comment giving it an overall 4 out of 5 stars.
