[2] Aendenboom started drama training in 1960 at the then very young Studio Herman Teirlinck, which was not officially recognized at the time.

He experienced his breakthrough as a stage actor in 1974 with his portrayal of The Poor Killer by Czech author Pavel Kohout directed by Walter Tillemans.

On television, he starred, among others, in the successful series Lili en Marleen (1994-2010), in which he played the character Rik, the rag-and-bone man and owner of the house with the café on Koolkaai in Antwerp.

[4] When he announced his retirement from his long and rich career in theatre, television and films on 3 September 2014, he did so with a certain professional detachment.

In fact, he largely saw it purely as a way to make a living, and then said a final goodbye to big business and to his successful career of almost 55 years.
