Eduard Zimmermann (4 February 1929 – 19 September 2009) was a German journalist, television presenter and security expert.

Eduard Zimmermann was born on 4 February 1929 in Alte Heide in the borough of Schwabing-Freimann in Munich, Germany to a teenage mother who worked as a waitress. Shortly before the Second World War Zimmermann moved to his grandparents house in Ottobrunn. At the end of the war Zimmermann moved to the city of Magdeburg where his mother had remarried to a hotelier, and where Zimmermann was first employed at his stepfather's hotel.

Following the Second World War the man who would later be known as a 'criminal hunter' and 'crook's bane' eked out a living as a thief and black market trader, for which he served a sentence at Fuhlsbüttel Prison. With a false identity and diploma he finally found work as a roadworks engineer in Sweden.

Zimmermann returned to the Soviet occupation zone in Germany on an assignment for Dagens Nyheter newspaper. There he was charged with espionage in 1950 and sentenced to 25 years in prison. He served five years of his sentence in Bautzen and was released early on 17 January 1954 under the Viermächtekonferenz (Conference of the Four Powers).

Diether Krebs (11 August 1947 in Essen, Germany – 4 January 2000 in Hamburg) was a German actor, cabaret artist and comedian.

Diether Krebs was born on 11 August 1947 in Essen, the son of a stationery shop owner. His godfather was Diether Posser, a lawyer, SPD politician and erstwhile Minister for Justice and Finance for North Rhine Westphalia. Krebs gained his first experience in the theatre at school at the Humboldt Gymnasium in Essen.

Of these, his most noteworthy appearance was in the film Zoff (1971) in which he played alongside well-known actors such as Jürgen Prochnow and Claus Theo Gärtner.

From 1973, Krebs became famous for his role as "Michael Graf" in the legendary comedy series Ein Herz und eine Seele, the German version of Til Death Us Do Part.
