This is the bookstamp of “Sa’adat Bahurim,” a society established in 1760 as a framework to support students of poor financial standing attending the Bet ha-Midrash de Ashkenazim be-Amsterdam ʻEts Ḥayim (house of learning for Ashkenazim) in Amsterdam, whose stamp also appears in the Brisman collection. Eventually this society became the financial branch of the Beit Midrash and used some of the funds to purchase books for the library.
The society continued to operate when the Beit Midrash was converted into a theological seminary and later assumed the name Nederlandsch Israëlietisch Seminarium te Amsterdam (as evidenced by one of the stamps pictured here).
Two versions of the society’s bookstamp appear in the Brisman collection. One is an ink stamp with Sa’adat Bahurim printed in the center in Hebrew. The second is an embossed stamp with Sa’adat Bahurim printed in the center in Hebrew surrounded by Nederlands Israelitisch Seminarium in Dutch.
