Reading Level: Middle Grades, ages 8-10

Recommended for: ages 7-11

Our story begins in the Netherlands, the 17th-century commercial center of the world. Dutch ships travel the globe planting colonies and trade empires and the scientific revolution is well underway. The curious son of a cloth merchant, Antony van Leeuwenhoek is following in his father’s trade, but with an interesting, and in time all-consuming, hobby. Lens grinding is a relatively new technology and curious gentlemen have been using it to explore the world of small things. But Antony has some ideas that will improve the simple magnifying glass and give human eyes the capability of seeing much smaller things. Even tiny animals in pond water whose existence no one suspected!

This engaging biography introduces third-through-fifth-graders to an age when any curious gentleman (or lady, like Maria Merian–see link below) could make breakthrough discoveries. The colorful, winsome illustrations are just right for drawing young readers into the story. Though Van Leeuwenhoek’s faith is not specifically mentioned, his sense of wonder comes through clearly.
