Roger Dommergue (full name Roger Dommergue Polacco de Menasce; b. 1923), is a French speaking Jewish professor, philosopher, and essayist, known for his writings concerning alternative medicine and his Holocaust scepticism.
Dommergue is a critic of contemporary claims concerning the Holocaust, Hitler, and National socialist Germany. He is especially critical of the claim that the number of Jews killed in the Holocaust was six million, as he claims that there were not even this number of Jews living in Germany or occupied Europe.
Dommergue is a critic of brit milah, claiming that infant circumcision performed on the 8th day after birth constitutes an infantile trauma and negatively affects hormone development, as Dommergue claims that the 8th day after birth is the beginning of the first puberty which lasts for 21 days thereafter. He claims that the endocrinologist Dr. Jean Gautier has given evidence of this.
