Funny, I'm Dutch and have an arts degree so obviously the name Van der Heyden is familiar to me, but I didn't know he was also an engineer who modernized our firefighting systems.

Having said that, "Dutch golden age painter invented better way to pump water out of the Amsterdam canals" sounds more like someone tried to cram as many stereotypes about the Dutch into a sentence than an accurate summary of something that actually happened, haha. I'm surprised it's real history.
