On Wikipedia it mentions "en wordt wereldwijd gezien als een van de grootste internationale dichters van de 20e eeuw." [1]

Translated to English (Stan is Dutch), that means that there's a Dutch consensus that this is seen worldwide as one of the biggest international poets of the 20th century. It should come to no surprise that a Dutch citizen who went to high school knows about such. It really sounds like something I'd have learned during CKV [2]
