1415 South Sawyer is on the near west side, which was the big Jewish
immigrant area in the late 1800's and early 1900's. It is 2 blocks south of
Roosevelt Rd. and between Kedzie and Kimball (bigger streets would be
California and Pulaski). There were scads of synagogues around there.
Sinai Congregation (reform) still exists, but it moved to downtown Chicago.
Try writing to the Asher Library (Dan) at Spertus Institute of Jewish
Studies, 618 S. Michigan, Chicago, IL 60605, and ask them, or look in the
yellow pages of a Chicago phone book >from 1936.
