In their deep-rooted love for learning, they sometimes ventured even beyond the German boundaries, into countries whose language and customs had little in common with theirs. Padua continued to be the resort of Russo-Polish Jews that it had been before 1648. Moses Hayyim Luzzatto found an ardent admirer and zealous propagandist of his principles in the young medical student Jekuthiel Gordon (ab. 1729), who wrote concerning his master to friends in Vienna and Vilna.[31] Judah Halevi Hurwitz (d. 1797), whose work _'Ammude Bet Yehudah_ (Amsterdam, 1765) was highly recommended by Mendelssohn and Wessely, was a graduate of the same famous institution. In addition to his medical and philosophic attainments, he wrote a number of poems, and he was among the first to translate fables from German into Hebrew.[32] The story of Zalkind Hurwitz (1740-1812), "le fameux," as he was called by a French writer, is interesting. Starting, as usual, by going to Berlin, and succeeding, as usual, in gaining the friendship of Mendelssohn, he then visited Nancy, Metz, and Strasburg, and finally settled in Paris. Like Doctor Behr, he had to resort to peddling as a means for a livelihood. The rudiments of French he acquired from any book he chanced to obtain. Nevertheless, he soon became proficient in the language of his adopted country, and wrote his excellent _Apologie des juifs_, which, crowned by the Academy of Metz and quoted by Mirabeau, was largely instrumental in removing the disabilities of the Jews in France. Clermont-Tonnerre, the advocate of Jewish emancipation, said of him, _Le juif polonais seul avait parle en philosophe_. He was suggested as a member of the Sanhedrin convoked by Napoleon in 1807. Though for some reason he never enjoyed the honor of membership in it, he was, nevertheless, the ruling spirit in the august assembly, and later generations have paid him the homage he deserves.[33] Where Hurwitz failed, another of his countrymen was to succeed. Judah Litvack (1776-1836) removed from Berlin to Amsterdam, became prominent among the Dutch mathematicians, and wrote a Dutch work, _Verhandeling over de Profgetallen Gen. ii_ (Amsterdam, 1817), which appeared in a second edition four years after the first. The author was elected a member of the Mathesis Artium Genetrix Society, and appointed one of the deputation sent to the Sanhedrin (February 12, 1807), before which he delivered a discourse in the German language.
