The Librarian Who Measured the Earth
This is a fascinating story, told for children and fully illustrated (beautiful full color pictures with interesting and at times humorous details) of the Greek Scientists, Mathematician and Astronomer - Eratosthenes. (Don't worry - the author does help you to pronounce the name). Eratosthenes was born in the 3rd century B.C. in the country we now call Libya to Greek parents. There he was educated in the classical Greel tradition and developed a keen interest in the world around him. As a young man he was sent to Athens to study where he became known as a scholar and historian.
