Auschwitz-Birkenau Museum historian Franciszek Piper denies that Hollerith machines were used to keep records at the camp. Edwin Black states that IBM assisted Hitler in carrying out the destruction of the Jews. Black makes the assertion in his book IBM and the Holocaust, published simultaneously in 20 countries in mid-Feburary. One of the most powerful images from American writer Edwin Black's IBM and the Holocaust is that of a Hollerith machine, using punch cards produced by IBM, standing in the Auschwitz administrative offices. Yet Franciszek Piper, director of the Research Department at the Auschwitz-Birkenau State Museum denies that there was such a machine at the camp. Nor were punch cards used to keep records on prisoners at Auschwitz, states Piper.
