One of the great things about this work is survey of the history of Jewish scholarship. It is worth noting the number of Jewish scholars mentioned who have been largely ignored. In particular, I was struck by the way Klausner discusses the way Albert Schweitzer’s seminal survey of the history of Jesus research pays hardly any notice to the work of Joseph Salvador, Jésus Christ et sa doctrine: histoire de la naissance de l’église, de son organisation et de ses progrès pendant le premier siecle (2 vols., Paris: A. Guyot et Scribe, 1838; 2nd ed., Paris: M. Lévy Frères, 1864–65).
The neglect cannot simply be chalked up to the fact that the work was originally written in French--as Klausner suggests--since Salvador’s work had been translated into German by the time of Schweitzer’s writing [cf. Das Leben Jesu und sein Lehre: die Geschichte der Entstehung der christichen Kirche, ihrer Organisation und Fortschritte während des ersten Jahhunderts (Dresden: Walther’s Buchhandlung, 1841)].
Strikingly, not only is Salvador’s work badly mischaracterized and mentioned only in passing, appearing under the section, "Further Imaginative Lives of Jesus," but Schweitzer even misspells his name (“Salvator”)! See Schweitzer's, The Quest for the Historical Jesus, 162.
By the way, a great antidote to this kind of neglect is Donald A. Hagner, The Jewish Reclamation of Jesus: An Analysis and Critique of Modern Jewish Study of Jesus (with a foreword by G. Lindeskog; Grand Rapids: Zondervan, 1984).
