title: Aspects of the history of the nerves: Bell's theory, the Bell-Magendie law and controversy, and two forgotten works by P.W. Lund and D.F. Eschricht.
abstract: The French physiologist François Magendie showed, in 1822, that the anterior roots of the spinal nerves are motor and the posterior sensory. The English anatomist Charles Bell claimed the discovery, but his claim was based on republications of papers in which the wording had been altered to be consistent with Magendie's findings. Bell also appropriated Herbert Mayo's discoveries of the functions of the fifth and seventh cranial nerves. Bell repeated his claims in a number of influential publications, supported by his brothers-in-law John and Alexander Shaw. And for a century and a half, Bell figured as the discoverer in most references to the subject. During this period, several reviewers did go back to Bell's original papers, disclosing Bell's falsifications in the republished texts. But Magendie was not definitely acknowledged as the discoverer of the function of the spinal nerve roots until Cranefield's (1974) treatise. Cranefield, as did all other reviewers, overlooked accounts from 1825 by P.W. Lund and F.D. Eschricht. They critically reviewed Bell's early publications and reached conclusions similar to those of Cranefield concerning the roles of Bell and Magendie in the discovery of the function of the spinal nerve roots.
