Jacob Schiff
Beth Hamedrash Hagodol had 175 member families by 1908, and the synagogue's annual revenues were $10,000 (today $). In 1909, the synagogue was the site of a mass meeting to protest the 20th Central Conference of American Rabbis, described as "the malicious misrepresentation of Judaism by the so-called reformed rabbis in conference in this city", and in 1913 the synagogue was the site of a "historic mass meeting" to raise funds for the first Young Israel synagogue, at which Jacob Schiff was the guest speaker. Membership had fallen to 110 families by 1919.
