Udo Jürgens (born Udo Jürgen Bockelmann; 30 September 1934 – 21 December 2014) was an Austrian-Swiss composer and singer of popular music whose career spanned over fifty years. He won the Eurovision Song Contest 1966 for Austria, composed close to 1,000 songs, and sold over 100 million records. In 2007 he additionally obtained Swiss citizenship.

He is credited with broadening German-language pop music beyond the traditional postwar "Schlager" (hit song) in the 1950s by infusing it with a modern pop appeal and French chanson style.
