Heinrich heine wrote the famous sentence "This is just a prelude. They burned books there, and they will eventually burn people there "(written in 1820, Bü cher Verblent, a Dortmund woman, and Auchamende Menschen, a Verblent man), just like a prophecy, the Germans proudly walked to the grave of the future.
Now in the center of Baerbel Square in Berlin, there is a book burning monument, and this sentence is engraved on the nameplate next to the monument.
There is such a passage that has been widely reproduced:
At the entrance of the concentration camp in Dachau, Germany, there is a famous warning from a poet in the17th century: "When a regime starts to burn books, if it is not stopped, its next step will be to burn people! When a regime begins to be silent, if it is not stopped, its next step will be to silence it! "
The entrance to the German concentration camp is generally only engraved with "Arbeit macht frei", that is, "labor brings freedom". The accuracy of this statement cannot be confirmed.
There is a blog post in Nazi May: "They burned books there and will eventually burn people there", which is a good reference for you.
