How did the world know about the Nazi holocaust?

Answer 1

From December 1941 onwards information reached Britain from the Polish underground and was passed on to the US. It seems that initially there was much skepticism about the accuracy of the reports. However, in November-December 1942 there was some discussion in the press in Britain of what, if anything, could be done to help the Jews, and it was at this time that a newspaper - the (London) New Chronicle - first used the word holocaust to describe what was happening in Poland and other parts of Eastern Europe.

For reasons that are unclear, public attention shifted elsewhere and very little of this information 'stuck' in the awareness of the general public.

Answer 2

The world began to find out about the Nazi Holocaust through several sources. British intelligence intercepted German reports of the Holocaust, escaped survivors from the concentration camps told their stories, and eyewitnesses.

Sources included the Jewish Socialist Bund Party, Gerhard Riegner, Jan Karski, and civilians from prisoner exchanges.

When the Soviets started to invade Nazi-German on there way to Berlin they would liberate country and as liberating they found concentration camps and with the survivors told the story to the Soviets, which told the world also.

There where a lot of other ways people found out but those where the most common.

In 1942 the Allies declared that they would try to end the extermination.

____________

The main source was reports from the Polish resistance, and these were for a long time treated with skepticism by the British government, though confirmed by British intelligence intercepts of wireless messages. The point above about the Allies in 1942 needs some comment. By late in 1942, the Allied governments in the West were aware that the Nazis were carrying out killings of civilians on a vast scale, but they were not at that stage aware that there was a policy of extermination.
