Ramsey Nasr

Ramsey Nasr (1974) is one of the most versatile artists in the Netherlands, known for his acting, poetry and writing. He has performed on stage in productions including The Fountainhead and A Little Life, on television in series such as IM, Het jaar van Fortuyn and Oogappels, as well as in films such as Alles op Tafel (2021). In his acclaimed collection of essays De Fundamenten (2021, De Bezige Bij), Nasr takes stock of the Netherlands during the coronavirus pandemic and makes an artists’ entreaty for a radical revision of our place on earth and our idea of happiness. Nasr regularly adds his voice to the debate on the value of art and culture within Dutch society, including in a poem he wrote as Poet of the Fatherland at the time of the wave of funding cuts in the cultural sector; a line from this serves as his personal motto: “out of unnecessary necessity / art created humanity”.
