LOS ANGELES (CBS) — A letter which first revealed Adolf Hitler’s radical anti-Semitic views is now on display for the first time, here in Los Angeles.

The Simon Weisenthal Center recently obtained the original “Gemlich Letter”, which is now on display at The Museum Of Tolerance.

Hitler wrote the letter in 1919 — six year before his famous manifesto “Mein Kampf” and 20 years before the Holocaust. It’s one of the earliest revelations of his deep anti-Semitism and his plan to eradicate the Jewish people.

In the letter, Hitler wrote that Jews were a threat to Germany during World War I and about using the government to remove Jews altogether.

When Hitler rose to power he went through with his plan, rounding up and exterminating millions of Jews across Europe by placing many of them in concentration camps.

Established in 1993, the Museum Of Tolerance engages visitors through interactive exhibits to “become witnesses to history and explore the dynamics of bigotry and discrimination that are still embedded in society today.”
