Günter Wilhelm Grass (born 16 October 1927) is a Nobel Prize-winning German author and playwright.
He was born in the Free City of Danzig (now Gdańsk, Poland). Since 1945, he has lived in West Germany (now Germany), but in his fiction he frequently returns to the Danzig of his childhood.
He is best known for his first novel, The Tin Drum, a key text in European magic realism. His works frequently have a strong left wing, socialist political dimension, and Grass has been an active supporter of the Social Democratic Party of Germany. In 2006, Grass caused a controversy with his disclosure of Waffen-SS service during the final months of World War II.
