The Comedian Harmonists were an internationally acclaimed all-male German close harmony ensemble that performed from 1928 to 1934. The group was founded by Harry Frommermann, who was inspired by the American group The Revelers. The original members included Harry Frommermann (tenor buffo), Asparuh "Ari" Leschnikoff (first tenor), Erich A. Collin (second tenor), Roman Cycowski (baritone), Robert Biberti (bass), and Erwin Bootz (pianist).

The group became one of the most successful musical acts in Europe before World War II, known for their ability to blend their voices seamlessly and their diverse repertoire, which included folk, classical, and popular songs of the day. They gained fame not only in Germany but also internationally, performing in the United States and appearing in 21 films.

However, their success was curtailed by the rise of the Nazi regime, which imposed restrictions on Jewish artists and banned the group due to its Jewish members. Their last concert in Germany was in March 1934. Subsequently, Frommermann, Collin, and Cycowski fled Germany and formed a new group in Vienna, while the remaining members continued in Germany as "Das Meistersextett." Neither group could replicate the original success of the Comedian Harmonists.

Despite their disbandment, the Comedian Harmonists left a lasting legacy with their recordings and performances, influencing future generations of musicians. Their story has been depicted in films and stage productions, highlighting their unique contribution to music and their struggle against the oppressive political climate of their time.
