Yeh, I always thought it was Fr-OH-bell but my university tutor says its FrOI-bell and a girl in my class pronounces it FrUH-bell. Was just wondering which, if any, of these were correct!
The sound of � doesn't really exist in English; however, if you know how to pronounce the French word for beef...ie boeuf...you've pretty-well got it, I'd say. Just put that in for the oe in Froebel.
