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. Land surveying and meteorology were encouraged as was astronomy: observation, measurement and classification during the Age of Enlightenment were the expression of a rational understanding of the world.
In the 18th century, cosmic events were mathematically described as verifiable and predictable physical processes. For instance at the famous Mannheim Observatory. Its historic inventory is kept at the TECHNOSEUM – apart from numerous instruments, you can also marvel at globes of the earth, the skies and the moon alongside 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 palace, the former seat of its patron, Carl Theodor.
