Abraham-Leib ben Yitshak Monsohn (Hebrew: ר' אברהם-לייב ב' יצחק מאנזאהן/מונזון), known as “Avrom-Leib Shames” (1804-1870), was a member of the first Ashkenazi prayer quorum of Perushim in the Old Yishuv community of Jerusalem at the beginning of the nineteenth century. He was born in Mogilev, and according to family legend, made his way to Jerusalem on horseback in 1832 with other students of the Vilna Gaon. His first wife was Zelda; he later married Dahde, believed to have been of the Maghrebim or North African Jewish community of Hebron (or maybe the references are to the same woman, using different names). Abraham-Leib was the first beadle and caretaker (shamash) of the Menachem Zion and Rabbi Yehudah He-Hasid (Hurva) synagogues in the Old City of Jerusalem, and of Rachel's Tomb on the outskirts of Bethlehem. He was also an aid to community leader Shlomo Zalman Zoref and in 1836 accompanied him to Egypt to obtain the permission of Muhammad Ali to build the Hurva synagogue. Abraham-Leib's son, Yoel Yosef Shimon Monsohn (Jerusalem, c.1843-c.1907), called “Shimen Shames,” later assumed the communal tasks his father had performed, by commission of Sir Moses Montefiore. He was in contact with communal leaders of the time such as Yosef Yoel Rivlin, and in fact with all the Russian Jews of the Old Yishuv, since he distributed the Jewish mail for the Russian post office in Jerusalem. Shimen Shames was married to Gittel (née Yofe), whose family migrated to Hebron with fellow members of the Chabad hasidic movement in Shklov in the 1820s. Members of the Monsohn family also intermarried with other Old Yishuv families such as descendants of the Schwartz, Honig and Getz Hacohen families. Shimen Shames’ son, Abraham-Leib II (Jerusalem, c.1871-1930), together with his brother Moshe-Mordechai (Jerusalem, c.1870-1940), were sent to Frankfurt in 1890 to study lithographic printing. Upon returning to Jerusalem with a hand press, they established the A.L.
