Born 1945 in Stockholm, Sweden. Lived and worked in Vagnhärad, Sweden.

Zennström's oeuvre includes several of the arts core functions in society. It reveals, concerns and upsets. Zennström used an in many ways unique combination of abstraction and representation, which sometimes took purely organic forms, with which he reduced the world into a micro cosmos where chaos often reigned. Zennström's motifs show an artist that had a strong and sincere commitment against social, political and economic injustice. The work creeps under the skin of the viewer thanks to the tense mood and the black humor. Zennström's humor works more clarifying than evasive, which contributes to the agitative direction of his artistry. He has exhibited widely both in Sweden and abroad. His work makes part of several collections in Sweden such as Moderna Museet, Nationalmuseum, Borås Konstmuseum, Göteborgs Konstmuseum, Malmö Museum, Norrköpings Museum and in Samtidsmuseet in Oslo, Norway. 

Petter Zennström sadly passed away in 2014.
