This article aims to investigate Nazi's practices and discourses about deaf people during World War II, from 1939 to 1945.The methodological approach adopted here was a qualitative one and it was carried out through a review of the bibliographical literature, mainly considering the American authors Biesold (1999) and Ryan & Schuchman (2002).Studies report that during the Nazi period, thousands of deaf people were subjected to eugenia, euthanasia and sterilization, caused by racial hygiene or cleansing policy, hoping they would not compromise future Aryan generations.Examining news stories and school materials of the time, it was discovered that the teachers and principals of these institutions were the main contributors to finding and identifying candidates for extermination, as it was considered wasteful to educate those people, perceived as "inferior".About 2,000 deaf children died from lethal injection or starvation during the Holocaust.The deaf-born were separated from their parents and taken to special rooms where they were killed by poisonous gas.Forced abortions have also been done on women suspected of being deaf children.Marriages between the deaf were not allowed.Based on this information, our results offer some historical knowledge about deaf people's past during World War II.More research is need, though.
