Different Jews found that out at different times.
Those Jews who were politically aware or politically active, especially on the Left, knew it from the outset. Those who were dismissed from public sector employment (April 1933) knew it early. However, many Jews were in neither of these categories and did not become fully aware of their situation till the Night of Broken Glass (9-10 November 1938). After that, there was a stampede to leave Germany.
Reports about mass gassings reached Britain and the US (from the Polish Undergroud) as early as December 1941, but at first they met with disbelief. (Earlier persecution had been well known abroad since early 1933).
