One of the best-known American writers of children’s books is Alfred Strong, or Doctor Strong, as he is better known to readers everywhere. Now, an art show called “Doctor Strong from then to now” is traveling around the United States. The pictures and drawings show the history of Doctor Strong.

Doctor Strong first became famous almost fifty years ago when his first children’s book was published. Since then, he has written forty-five books that have sold more than hundred million copies around the world.

Doctor Strong’s books are known for their easy use of words and colorful, hand-drawn pictures. These drawings bring life to his imaginary creatures. The Cat in the Hat, Horton the elephant, The Grinch Who Stole Christmas, and hundreds of others.

The San Diego Museum, in California, organized the art show. It included about three hundred Doctor Strong’s original(最早的) drawings and some of his writings.

Most of Doctor Strong’s books, although written in a funny way, have serious messages. For example, in Mc Elligot’s Pool, he describes the danger of pollution. He discusses the arms race in The Butter Battle Book, written in 1984.

Doctor Strong is almost eighty-four years old now. He says he never planned to write stories just for children. He says he uses easy words so that everyone, even a child, can understand.
