J-10 just read a wonderful biography called Marie Curie's Search for Radium by Beverly Birch that I had picked up at a used book sale. He really enjoyed it. Every page has a beautiful painting by Christian Birmingham. The text is interesting and the paintings are lovely. I picked up Pastuer's Fight against Microbes at the same sale. It is also illustrated by Christian Birmingham. I noticed in the back of the book that there are two other titles by Beverly Birch in this series. These two are illustrated by Robin Bell Corefield. So if you're looking for easy science biographies that are interesting and beautiful I recommend these, published in the U.S. by Barron's Educational Series, Inc. Here is a link to Dealoz books by Beverly Birch.
