Yeah the people who were cataloging all the species of beetles in Germany were upper class types. Most people in 1820 were tilling fields or working in desperately terrible factories.
The 1800s gave us the likes of Michael Faraday the 2000s gave us the likes of Hank Green.
Came here to effectively say this. If we were people in 1820's Germany, 99% of us wouldn't have nearly enough spare time to even think about cataloging those beetles.
