Seth Lipsky found this quote about Herr Ahlwardt, the German anti-Semite whose visit to New York in 1895 caused an uproar among the city's appropriately upset Jews. Apparently Roosevelt was ready for the controversial appearance:
"While I was Police Commissioner an anti-Semitic preacher from Berlin, Rector Ahlwardt, came over to New York to preach a crusade against the Jews. Many of the New York Jews were much excited and asked me to prevent him from speaking and not to give him police protection. This, I told them, was impossible; and if possible would have been undesirable because it would have made him a martyr. The proper thing to do was to make him ridiculous. Accordingly I detailed for his protection a Jew sergeant and a score or two of Jew policemen. He made his harangue against the Jews under the active protection of some forty policemen, everyone of them a Jew! It was the most effective possible answer; and incidentally it was an object-lesson to our people, whose greatest need it is to learn that there must be no division by class hatred, whether this hatred be that of creed against creed, nationality against nationality, section against section, or men of one social or industrial condition against men of another social and industrial condition. . . .
