The idea had already been expressed by Reuss, but since Graf was the first to introduce it into Germany, the theory, as developed by Julius Wellhausen, has been called the Graf–Wellhausen hypothesis.
Idén hade redan uttryckts av Édouard Guillaume Eugène Reuss, men eftersom Graf var den förste som framförde den i Tyskland har teorin, som den utvecklades av Julius Wellhausen, kallats Graf-Wellhausen-hypotesen.
