I would love to see a collection with German inventions. I picked some examples from this list: https://www.wiwo.de/erfolg/trends/erfindungen-aus-deutschland-17-beruehmte-deutsche-erfindungen/26701472.html

Letterpress by Johannes Gutenberg

Motorcycle and Car by Gottlieb Daimler und Carl Benz

X-radiation by Wilhelm Conrad Röntgen

35 mm camera by Oskar Barnack (Leitz Camera)

TV by Manfred von Ardenne

Computr bei Konrad Zuse

On the list in the link there are some more but that was my pick.
