Jules Feller created the Feller system [wa] of spelling for the Walloon language. This is also used for writing the Picard language since a consensus arose between universities in favour of the written form known as Feller-Carton (based on the Walloon spelling system – which was developed by Feller and adapted for Picard by Prof. Fernand Carton).

He represented Verviers in the Walloon Assembly [fr] from 1919 until his death. He was a member of the Royal Academy of French Language and Literature in Belgium.
