Wilhelm Roentgen

Wilhelm Roentgen was a German physicist who lived between 1845-1923. He discovered x-rays, a type of radiation which can pass through material that ordinary light cannot.

X-rays have many important uses in medicine, allowing us to view the inside of something, like a body, without having to open it. Today, we use x-rays to locate bone fractures, cancerous tumors, or tooth cavities.
