Columbia Magazine reports:
In 1933, soon after Hitler came to power, the Nazis began expelling Jewish students and dismissing Jewish professors from their universities. On campuses across Germany, Nazis and their sympathizers publicly burned books written by Jews and other perceived enemies (including books by Columbia anthropologist Franz Boas).
There's more:
Just months after the first book burnings, Columbia president Nicholas Murray Butler welcomed Hans Luther, the German ambassador to the United States, to Morningside Heights, insisting that he be accorded “the greatest courtesy and respect.”
Great moments of Columbia University.
