'Alexander Altmann's monumental new biography not only supersedes the Kayserling study but should also serve as a turning point in the historical re-evaluation of Mendelssohn's role in the process of Jewish emancipation . . . The happy combination of all these qualities in Professor Altmann makes his work a major achievement of scholarship.'
Jacob Katz, Commentary
'There is an overpowering effect on the reader in studying the results of Professor Altmann's facts compiled as a biography and emerging as so much more: as history, as a record of controversies over religious adherence and strict and faithful Jewish observance, as theological disputation, as remarkable reporting on the philosophic discourses with noted Christians as well as Jews, as commentary on Jewish laws by the hero of the book whose piety and Jewish devotions are respected to this day . . . Altmann's creative work excels in many respects. It is history par excellence. It is thorough research. It is unsparing in criticism and it recognizes the merits of controversy. It will rank as an indestructible work and will be among the classics in biographic literature.'
Detroit Jewish News
'An influential educator and author of many monographic studies in the history of Jewish philosophy, Professor Altmann has here presented what may indeed become the definitive biography of Mendelssohn . . . even our fast-moving generation will find the reading of this lucidly written and often eloquent volume highly rewarding.'
Salo W. Baron, Jerusalem Post Magazine
'This monumental work is now required reading for everyone interested in Jewish intellectual history and in the spiritual, cultural, and religious development of the Jewish people in modern times.'
Moshe Pelli, Jewish Quarterly Review
'Generally, Judaica books published by university presses are definitive studies certain to be "classics" a hundred years from now. Among these is Alexander Altmann's biography . . . This is a definitive biography . . . it is written in a beautiful style . . . I predict that one hundred years from now . . . Moses Mendelssohn will be read and studied in new and reprinted editions.'
Jewish Spectator
'Admirablement équilibrée, faisant sa juste part aussi bien au récit "événementiel" qu'au tableau psychologique et � l'analyse doctrinale, l'étude de Manfred Altmann peur se prévaloir, parmi d'autres qualités dont l'érudition proprement judaïque n'est pas la moindre, de la maîtrise totale, chose bien rare, que l'auteur possède tant de sa langue d'origine que de sa langue d'adoption . . .'
G. Vajda, Revue des Etudes Juives
'Altmann . . . hat mit seiner großen Mendelssohn-Biographie wohl für mehere Generationen ein Standardwerk geschaffen, an dem kein Philosophiehistoriker, kein Geistesgeschichtler, Religionswissenschaftler oder Judaist vorbeigehen darf, der sich künftig mit Mendelssohn, seinem Kreis und seiner Epoche beschäftigen will.'
