After the Fast, a bookdealer at Wollstein, a friend of his, who usually kept him informed about new books on Jewish subjects, sent Graetz the “Nineteen Letters by Ben Usiel,” which he had longed to possess. The book again electrified him, and he conceived the idea of offering himself as a disciple to its author, whose identity had meantime been revealed. Samson Raphael Hirsch appeared to him to be the ideal of a Jewish theologian of the time and of the confidence-inspiring teacher for whom he had yearned, to obtain from him guidance and, if possible, a solution of the manifold problems occupying his mind. Accordingly, Graetz wrote to the District Rabbi (_Landesrabbiner_) of Oldenburg. He did not conceal his views, but clearly and frankly laid bare the state of his feelings and the course of his intellectual development. He was successful. After a short time, Hirsch addressed the following letter to him: “My dear young Friend:--With pleasure I am ready to fulfill, as far as in me lies, the wish expressed in your letter to me. You know the sentence of our sages, יותר משעגל רוצה לינק הפרה רוצה להניק {Hebrew: Yoter mishe’egel rotzeh linak, haparah rotzah l’hanik},[6] and if, as I should gladly infer from your letter, the views therein expressed are more than an evanescent mood; if it is your resolute determination to study _Torah_ for its own sake, you are most cordially welcome, and I shall expect to see you after פסח הבע''ל {Hebrew: Pesach haba aleynu l’tovah}.[7] But I have one request to make. In the ardor of your feelings, you have conceived an ideal picture of the author of the ‘Letters’ by far exceeding the real man in size. Reduce the picture by half, by three-fourths, indeed, and ask yourself whether you are still attracted by it. Do not expect to find an accomplished master, but a student occupied with research. If your heart still says _yes_, then come. I should like to be informed as soon as possible, whether I may expect you after _Pessach_, as I shall have to modify another relation accordingly. Be kind enough, too, if you have no objection, to let me know how you expect to support yourself here. I trust that you will neither take umbrage at this question nor misconstrue it. It was put only because I wanted to express my willingness to assist you as much as I can during your stay here, if it should be necessary. Therefore, I beg you to be as frank and unreserved in your answer as I ventured to be in my question. With kindest regards, etc. OLDENBURG, December 26, ’36.”
