As the World is shrinking due to Globalization, learning a foreign language is an undoubted asset. While it is not a problem to communicate in English at research institutes in Germany, there are still plenty of good reasons for at least having a basic knowledge of German. Language is not only a window to scientific journals or technical books, but it is also a window to its culture and people. It can help you integrate more easily into everyday life. Hence, it would be helpful to learn the basics before your research stay. For natural scientists and engineers, good knowledge of English or German is sufficient. Scholars in the humanities and social sciences should have profound knowledge of German for the successful completion of a research project in Germany. In the case of physicians, especially if the research involves work with patients, the candidate must have a good knowledge of German.
