What languages did Joseph Pulitzer speak?

Joseph Pulitzer was born in Hungary and emigrated to the United States at a young age. He spoke Hungarian as his native language and learned English after arriving in America.

It's highly likely he also had some fluency in German, as it was a prominent language in many parts of Europe at the time, and the German language was influential in the development of Hungarian. However, there's no concrete evidence that he was fluent in German.

So, we know for certain that Pulitzer spoke Hungarian and English. It's possible he also spoke German, but we can't be sure without further evidence.
