Elector Carl Theodor (1724–1799) showed a keen interest in sciences and the fine arts. During his reign, Mannheim became a major centre for scientific research. Surveying and meteorology were encouraged as was astronomy – observation, measurement and classification during the Enlightenment era were valued as expressing a rational understanding of the world.
In the 18th century, celestial events were described mathematically as verifiable and predictable physical processes, e.g. at the famous Mannheim Observatory. Its historic inventory is kept at the TECHNOSEUM – apart from numerous instruments, you can also admire globes of the earth, the skies and the moon along with a model of the observatory itself. The original of the latter can also be seen in Mannheim’s city centre – of course within sight of Mannheim’s castle, the former seat of its patron, the elector.
