Milton Meltzer wrote 110 books, five of which were nominated for the National Book Award. With Langston Hughes, he co-authored A Pictorial History of Black Americans, now in its sixth edition. He received the 2001 Laura Ingalls Wilder Award for his contribution to children's literature, the 1986 Jane Addams Peace Association Children's Book Award, and the 2000 Regina Medal. He died in New York City of esophageal cancer at age 94.
The only reason this has two stars is because Meltzer did an amazing job explaining the origin of the Bill of Rights. I have to give him credit. However, in the second half of the book, Meltzer became highly politicized in the second portion or "What It Means" section. Instead of giving the reader a chance to think on what each of the 10 amendments means or even providing all arguments for or against amendments, he explained events and interpretations that were entirely one sided. Per the first amendment he does have to right to express himself anyway, however, if you are hoping to provide a neutral presentation of the Bill of Rights for your child to think and reason on their own, you will have to find another book.
