This chapter book biography shows how a self-taught scientist was the first to observe the microbial life in and around us. By building his own microscope, Antony van Leeuwenhoek advanced humanities understanding of the oft-invisible world around us.

Readers will learn about the science behind the discovery of germ theory and how germs spread.

Text and photographs show young readers how scientists use microscopes and hand lenses to make up-close observations.

Describes the work of Dennis Kunkel, a microscopist from Hawaii, and provides illustrations of microscopic worlds of plants, bugs, and mites.

Invisible microbes cause sickness by invading our bodies and multiplying. But doctors didn't always know that sickness was caused by germs. Most people thought diseases came from smelly, damp air. But over time, those ideas changed. A Dutch scientist saw bacteria through his microscope. Doctors realized that when they washed their hands, fewer people died. And a doctor in London recognized that disease could spread through contaminated water. Because of these discoveries, people eventually learned that hygiene was the key to stopping disease. Hospitals used clean surgical instruments, and cities developed trash removal and sewage systems. Learn more about the discovery and defeat of bacteria!.
