Once upon a time, taking a picture was a big deal, and a photographer named Israël Kiek became so famous that his name became a word for 'picture' in the Netherlands.
Kiek was known for taking funny photos of students, even though he didn't like their silly behavior.
Even today, Dutch people still use the word 'kiekjes' for 'pictures', even though most have forgotten where it came from.
In Leiden, there's a special place that remembers Kiek and his funny photos.
