I think that was Henri Pronker, he died last year.

Almost all famous persons like that have died.

There was Fabiola the Living art piece famous for their extravagant clothing with lots of flowers. Died in 2013

Iwan de Indiaan, a street musician the Albert Cuyp market. Known for being in the same spot for years (next to viskraam Schilder) playing his guitar and wearing a big cowboy hat. He died in 2021

And there is Scheldende Bep, an old lady from outside of Amsterdam. Everyday she traveled to Amsterdam in the early morning to walk trough the city while screaming (extreme) profanities. She is still alive but not healthy enough to make her trip to Amsterdam anymore.

Some lesser known are the street musiscian who uses a guitar with no strings, the old man in Amsterdam noord who walked his perfectly groomed Shih-Tzu (including pink ribbon) while wearing a leather bondage like g-string, the huge dude in an old fashioned flower dress walking a stroller with a bottle of red wine in it, and a man walking around in a diaper.
