Rune T. Kidde was a multi-talented artist and has released both humorous cartoons, poems, novels, children's books and biographies.
In 1979 he co-founded the cartoon studio Gimle together with fellow cartoonist Peter Madsen and in 1984 was a founding member of Tegneserieværkstedet (the comics workshop).
Rune T. Kiddes own debut as cartoonist was the albums "Rune T. Kidde" and "De siger så meget" (They say so much) in 1980 and up through the 1980s he released a number of comics, as well as the illustrated handbook "Øldrikkerens Lille Grønne" (The Beer Drinker's Little Green – a pun on chairman Mao's Little Red Book).
Still, Rune T. Kidde continued to produce comics and picture books, where other artists – especially Jørgen Mogensen – drew according to his directives.
From 1980–1981 he worked as an editor at the comic book publishing company Interpresse, where he edited The Phantom, Beetle Bailey, Komix and Underground.
The insecure upbringing was, Rune T. Kidde himself thought, a strong contributing factor to the fact that at the age of 15 he suffered from severe depression, which plagued him until he turned 30.
But there was another side of the coin, a black sense of humour, which - as he eventually gained control of his creative urge - enabled him to live with his depressions.
Kidde made his debut as a playwright in 1983 with the play "En måge over Ejer Bavnehøj" (A seagull over Ejer Bavnehøj) at Det Danske Teater and as an actor in 2005 in Jon Bang Carlsen's English language movie Blinded Angels which takes place in Cape Town in South Africa.
