The name bundle of Türck has become synonymous with the temporopontine tract. As details concerning this pathway have been confusing and incomplete we reviewed the papers of Ludwig Türck (18101868) to determine what in fact he originally described. Türck's pioneering degeneration studies provided great detail concerning the corticospimal tracts. Charcot recognized his contributions and used the eponym bundle of Türck to denote the anterior corticospinal tract. Türck did not observe projections from the temporal lobe to the basis pontis, nor did he describe a temporopontine tract located at the most lateral aspect of the cerehral peduncle. The papers of Meynert, Flechsig and others reveal the origins of the current incorrect use of the eponym.
