WebX-rays were discovered in the 1890s by German scientist Wilhelm Roentgen, who realized that photographs taken with X-rays allowed him to see through objects. Roentgen thought he'd gone insane when he saw this. But today we're all familiar with X-rays from trips to the dentist and doctor. Chemists don't use X-rays to see through things, however.
