Helge Hansen began his career drawing for Dansk Familieblad in the 1930s. For this magazine, he created the comic strip 'Styrmand Rask' with writer Paul Hilsø in 1942. The strip, a romantic adventure comic set in Africa, was created as a replacement for 'Flash Gordon'. The series ended in 1958. It also ran in Lektyr in Sweden from 1945 to 1954. By then, he started 'Ann - Jungletemplets Gåde', a series written by Helge Hall's brother Arne Hall Jensen. This strip ran in the Ude og Hjemme supplement Ugemagasinet from 1951 to 1955, and was continued in the regular pages of Ude og Hjemme until 1962.
Hansen's final comic was the western serial 'Præriedoktoren', that appeared from scripts by Arne Hall in Ude og Hjemme in 1962 and 1963. Hansen is best known as anillustrator for Danish 'Sherlock Holmes' novels and the book series 'Jan'. Until his retirement in the 1970s he also worked as a magazine illustrator and cartoonist for the P.I.B. agency. He passed away in the early 1990s.
