Adolf Hitler's hatred for Jews stemmed from his belief that a Jewish doctor poisoned his mother, a new book by Joachim Riecker claims.

In a Monday report in the British Daily Telegraph, Riecker claims that the future dictator believed his mother, who died of breast cancer at the age of 47, was in fact poisoned by her physician, Dr. Eduard Bloch.

“Hitler never forgave the Jewish doctor. In conversations with aides such as Josef Goebbels he referred to the Jews as being like TB and himself as a ‘healer’ who had to stamp it, and consequently them, out,” Riecker says in the book.

The arguments in the book, titled "November 9: How World War One Led To The Holocaust," contradict other views that Hitler respected and liked Dr. Bloch, even helping him to emigrate from Austria to the US in 1940.

Riecker chose to focus on November 9 as a key date for Hitler since on that day in 1918, the Weimar Republic was formed. Hitler staged an attempted coup in 1923 and the Kristallnacht pogrom against Jews happened on the same date in 1938.
