These were usually quite small, and a single synagogue might be associated with more than a few such organizations. Two of the most important of these merged in 1859 to form the Hebrew Benevolent and Orphan Asylum Society[1] (Jewish orphanages were constructed on 77th Street near 3rd Avenue and another in Brooklyn). In 1852 the "Jews' Hospital" (renamed in 1871 Mount Sinai Hospital), which would one day be considered one of the best in the country,[23] was established.[21]
