Visited Julius Zichlinsky
Julius Zichlinsky was the brother of Brooklyn's own Jack Zichlinsky, and both were, I am told, members of Papa's Zionist fraternal organization, Order Sons of Zion (a.k.a. B'nai Zion).
As we've discussed before, such groups provided essential services to immigrants like Papa; B'nai Zion sold affordable life insurance, guaranteed its members a proper Jewish burial, and ran a credit union that Papa and Jack helped organize. I'm not sure if fraternal orders guaranteed friendship among its members as well, but Julius and Jack were two of Papa's closest companions in 1924 and, in fact, remained so for the rest of their lives.
