In the final months of the war, Norbert Wollheim already was starting to make notes in shorthand about his time in the camp and about the death march, as his close friend Albert Kimmelstiel tells us. After his emigration to the United States in 1951, Norbert Wollheim lived in New York, where he told U.S. author John Hersey the story of his survival. Hersey used this account as the basis for his story “Tattoo Number 107,907,” published in Here to Stay, a collection of journalistic pieces, in 1963. In the 1980s and 1990s, Norbert Wollheim gave two oral-history interviews, which were videotaped and are also available in transcription.
