Comment by tonytran2015: The figure 6 million may even have arrived from documents from 1939:
The Evening Independent, St Peterburg Florida, Wednesday, February 22, 1939.
The Palm Beach Post, Tuesday Morning, June 28, 1940.
Boston University’s director of the Elie Wiesel archive, Bar-Ilan University’s Institute of Holocaust Research historian Joel Rappel has discovered the origin of the infamous “6,000,000” number: a 1944 meeting of Zionist pioneering organizations in what is now known as the state of Israel.
For years, supporters of the Holocaust narrative have held that the number first appeared at the Nuremberg trials using highly discredited testimony by Auschwitz commandant Rudolf Hoss. The 6,000,000 figure was again repeated by Adolf Eichmann, who was kidnapped by the Mossad and forced to participate in an internationally televised 1962 show trial in Israel.
According to documents in the Central Zionist Archive, the first mention of the 6 million claim was at a meeting of high ranking Zionist political figures in Palestine on January 19th, 1944 — more than a year before the war in Europe ended and a census could be taken, and a year before the Red Army entered Auschwitz.
