In 2019, Alexander von Humboldt was very present in the media, as his 250th birthday was celebrated. Television programs, newspapers, and new books euphorically reported on a man who had achieved superhuman things.

This glorification and hero worship sometimes degenerated into a completely exaggerated cult of saints. But saints, as we know, are often fictitious creatures or hypocrites.

Or was he not sexually active during the five years of his journey?
