Odd Boy Out: Young Albert Einstein by Don Brown
This is the first picture book about Einstein that I have seen and enjoyed. It really is wonderfully written and illustrated to capture the most interesting parts of his life, without skipping the important ones :o)
For example, "The Einsteins move to the large city of Munich. There, Albert's parents encourage his independence and take the unusual step of allowing four year old Albert to wander the streets unattended." Accompanied by a 2-page illustration showing a bustly town and little Albert standing there . . .
