[1] Karl Dall left school after the 10th grade and accomplished an apprenticeship as a typesetter in a print shop in the town of Leer, East Frisia.

From 1983 until 1990, Dall used to appear in the hidden camera comedy show Verstehen Sie Spaß?, playing for example a chaotic film presenter or a telephone prankster.

From 1991 until 1993, Dall presented the game show Koffer Hoffer on television channel Tele 5.

On 23 October 2020, precisely a month before his untimely death, Dall evaluated his participation as the lead in the upcoming theater-farce WIN=WIN about social distancing during the COVID-19 pandemic.

According to its author-producer Roger Steinmann, he seemed fit and eager, "having read the entire play within five hours".
