The Threepenny Opera in the context of "Kurt Weill"

Eugen Berthold Friedrich Brecht (10 February 1898 – 14 August 1956), known as Bertolt Brecht and Bert Brecht, was a German theatre practitioner, playwright, and poet. Coming of age during the Weimar Republic, he had his first successes as a playwright in Munich and moved to Berlin in 1924, where he wrote The Threepenny Opera with Elisabeth Hauptmann and Kurt Weill and began a life-long collaboration with the composer Hanns Eisler. Immersed in Marxist thought during this period, Brecht wrote didactic Lehrstücke and became a leading theoretician of epic theatre (which he later preferred to call "dialectical theatre") and the Verfremdungseffekt.

When the Nazis came to power in Germany in 1933, Brecht fled his home country, initially to Scandinavia. During World War II he moved to Southern California where he established himself as a screenwriter, while also being surveilled by the FBI. In 1947, he was part of the first group of Hollywood film artists to be subpoenaed by the House Un-American Activities Committee for alleged Communist Party affiliations. The day after testifying, he returned to Europe, eventually settling in East Berlin where he co-founded the theatre company Berliner Ensemble with his wife and long-time collaborator, actress Helene Weigel.

Captain Macheath is a fictional character who appears both in John Gay's The Beggar's Opera (1728), its sequel Polly (1777), and 150 years later in Bertolt Brecht's The Threepenny Opera (1928).

"Mack the Knife" or "The Ballad of Mack the Knife" (German: "Die Moritat von Mackie Messer") is a song composed by Kurt Weill with lyrics by Bertolt Brecht for their 1928 music drama The Threepenny Opera (German: Die Dreigroschenoper). The song tells of a knife-wielding criminal of the London underworld named Macheath, the "Mack the Knife" of the title.

The song has become a popular standard recorded by many artists after it was recorded by Louis Armstrong in 1955 with translated lyrics by Marc Blitzstein. The most popular version of the song was by Bobby Darin in 1959, whose recording became a number one hit in the US and UK and earned him two Grammys at the 2nd Annual Grammy Awards. Ella Fitzgerald also received a Grammy for her performance of the song in 1961.
