Books On Famous Scientists for Children

I am currently reading a biography on Einstein and His Life. J was curious about what I am reading, but the book is not suitable for him. But I have found some books which are suitable for J:

Galileo Galilei (1564-1642):

Isaac Newton (1643-1727):

   

Benjamin Franklin (1706–1790)

Thomas Edison (1847-1931)

Albert Einstein (1879-1955)
