Édourd Aidans began his career in the magazine Spirou, where he illustrated some 'Belles Histoires de l'Oncle Paul' in 1955. A year later, he started making several short stories for the magazines Line and Tintin. He became one of the main artists of Tintin in 1960, when he drew the continuing story 'Le Dossier Vert'. The same year, he created the humorous reporter 'Bob Binn' with scripts by André-Paul Duchâteau and later Jacques Acar. In addition to the comics, 'Bob Binn' became a regular character in Tintin's games section.

In 1962, Aidans came up with the realistic pre-historical comic 'Tounga', for which he also wrote the texts. Aidans started a third series in 1963, 'Marc Franval', which was scripted by Jacques Acar and later Yves Duval. While continuing to work for Tintin, Aidans drew 'Alex Vainclair' for Pilote scripted by Duchâteau in 1965. He teamed up with Greg and began 'Les Panthères' in Tintin in 1971. Four years later, he began 'Gour le Ba-Lourh' in Achille Talon Magazine.
Aidans joined the magazine Super-As in 1979, where he created the series 'Tony Stark' with scripts by Jean Van Hamme. For the publishing house Dargaud, he came up with the historical saga 'La Toile et la Dague' from 1986 (text by Jean Dufaux).
Again with Greg, he created new stories with 'Bernard Prince' at the publishing house Blanco from 1992. In 1995, he began producing 'Les Saintes Nitouches' in the erotic magazine Klin Deuil, adapting the pseudonym Hardan. The same year, he began producing new stories for the series 'Tounga'.
