Nena rose to international fame in 1983, when her single "99 Luftballons" became a hit in many countries. The song was written by Uwe Fahrenkrog-Petersen and produced by Dieter Bohlen, who also produced many other hit songs for German artists in the 1980s. "99 Luftballons" was originally released in German, but was also translated into English and other languages.
