Radis was first documented in 1378 under the name Rodiß.
The Papsthaus ("Pope House"), located in a wooded area about 2 km west of Radis, was where Johann Gottfried Galle (1812–1910) was born. With his startling discovery of the planet Neptune, among other things, he became one of Germany's most important astronomers.
