"Keneally wrote the Booker Prize-winning novel in 1982, inspired by the efforts of Poldek Pfefferberg, a Holocaust survivor. In 1980 Pfefferberg met Keneally in his shop, and learning that he was a novelist, showed him his extensive files on Oskar Schindler. Keneally was interested, and Pfefferberg became an advisor for the book, accompanying Keneally to Poland where they visited Kraków and the sites associated with the Schindler story. Keneally dedicated Schindler's Ark to Pfefferberg: "who by zeal and persistence caused this book to be written." He said in an interview in 2007 that what attracted him to Oskar Schindler was that "it was the fact that you couldn't say where opportunism ended and altruism began."
