Fackenheim's affirmation of his Jewish heritage, although embraced by many other Holocaust survivors, was by no means universal. Physicist Lise Meitner had been born and brought up Jewish. She rejected newspaper attempts to characterize her as a Jew following the bombing of Hiroshima when the press learned that she had been the first scientist to recognize nuclear fission. Decades before Hitler rose to power she had become a Lutheran. Although the Nazis stole her savings and ruined her career she refused to work on the bomb or let Hitler define her identity.
