Hugo Wilhelm Ludwig Kaun was a German composer, conductor, and music teacher. Kaun was born in Berlin, and completed his musical training in his native city. In 1886 (or 1887), he left Germany for the United States and settled in Milwaukee, which was home to a well-established German immigrant community . As the conductor of local choral societies such as the Milwaukee Liederkranz and the Milwaukee Men's Choir, Kaun quickly acquired an important influence over the city's musical life. He also taught at the conservatory, where his colleagues included Wilhelm Middelschulte. Kaun's eldest son, Bernhard Kaun, later became a composer of film scores in Hollywood.
