4 Stars Out Of 5
This is a great simple read of Mueller's life
January 15, 2013
Initially, I was disappointed because I thought the book was an "adult-level" book; once I started reading it, however, I found it simple, yet well written and a concise summary of his life and work. I enjoyed its simplicity. I would highly recommend this for junior/senior high students or as a great family-read book for younger children.
