The epic is widely credited to Turold because at the of the end of song is this:

"So ends the tale which Turold hath conceived."  
(My copy is translated by C. K. Moncreiff.)

But it's still generally considered as an anonymous Old French epic  I hope you could read a translation of D.R.R. Owen, where in his introduction, he discussed who could be the author of the epic.
